Peking University received 1 billion yuan personal donation legal report, Li Yongxin, founder and President of Peking University, the outstanding alumni of Peking University. Today, Peking University is the top university in the whole country. Every year, the top notch students in the whole country are admitted to Peking University, and Peking University has trained a group of outstanding students in the past, and the
has been trained by the University. It has trained generations of talents for the country
Li Yongxin was born in Jilin Province in Northeast China. He graated from the Department of political science and administration of Peking University in 1999. He is the founder and President of China public ecation group. He is the pioneer of China public examination and training, and now the president of China public ecation group. Li Yongxin, a pioneer in China's public examination and training instry, won the Sohu 60 years 60 people China Ecation Achievement Award in 2009 and the annual outstanding contribution ecation Figure Award in 2011. On March 3, 2021, his alma mater Peking University donated 1 billion yuan to establish Peking University public ecation development fund, which is the largest indivial donation since the founding of Peking University
Excavator usually say 60, 85, 200, 220, 250, 300 this number represents the model and bucket capacity
the model is 60, which means that the capacity of 6-ton bucket is about 0.3 cubic meters
the model is 85, which means that the capacity of 8-ton bucket is about 0.6 cubic meters
the model is 200, which means that the capacity of 20 ton bucket is about 0.8 cubic meters
the model is 220, which means that the capacity of 22 ton bucket is about 1.1 cubic meters
the model is 250, which means that the bucket capacity of 25 tons is about 1.2 cubic meters
the model is 300, that is, the bucket capacity of 30 tons is about 1.6 cubic meters
daily maintenance precautions of excavator:
daily inspection is an important link to ensure that the hydraulic excavator can maintain efficient operation for a long time, especially for the self-employed, daily inspection can effectively rece the maintenance cost
first, rotate the machine twice to check whether the appearance and the mechanical chassis are abnormal, and whether there is grease flowing out of the slewing bearing, then check the deceleration braking device and the bolt fasteners of the crawler, the tightening and replacement should be timely replaced, if it is a wheeled excavator, it is necessary to check whether the tires are abnormal, and the stability of the air pressure
check whether the bucket teeth of excavators have large wear. It is understood that the wear of bucket teeth will greatly increase the resistance in the construction process, which will seriously affect the work efficiency and increase the wear degree of equipment parts
check the stick and cylinder for cracks or oil leakage. Check the battery electrolyte to avoid being below the low level line. The air filter element is an important part to prevent a large amount of sty air from entering the excavator, so it should be checked and cleaned frequently. Often check the fuel, lubricating oil, hydraulic oil, coolant, etc., whether it needs to be added, and it is best to select the oil according to the requirements of the manual, and keep it clean
It's called a breaking hammer or a gun head
hydraulic breaking hammer has become an important operation tool of hydraulic excavator, and it is also installed on the backhoe loader or wheel loader. Hydraulic hammer is also called hydraulic breaker or hydraulic breaker
this term is often used in Japan and South Korea. It is also called hydraulic hammer, which is often used by companies in Finland and Germany. In China, some manufacturers and users call it hydraulic crusher, others call it hydraulic pick, hydraulic gun, gun machine, crushing head, woodpecker and so on. The term of our national standard is called hydraulic impact breaker
Although the names are various, they all refer to the same machine. This machine is driven by hydrostatic pressure to drive the piston to move back and forth. When the piston stroke, it impacts the drill rod at a high speed, and the drill rod breaks up solids such as ore and concrete
extended data
there are many kinds of hydraulic breaking hammers and many classification methods
according to the operation mode, the hydraulic hammer can be divided into two categories: hand-held and airborne. According to the working principle classification: hydraulic crusher is divided into three categories: full hydraulic type, liquid gas combined type and nitrogen explosion type
Most of the crushers belong to this kind of procts; According to the valve structure classification: hydraulic crusher is divided into internal valve type and external valve typein addition, there are other classification methods, such as stroke feedback crusher and pressure feedback crusher
According to the noise level, it can be divided into low noise crusher and standard crusher According to the type of shell, it can be divided into triangle and tower crusher According to the shell structure, it can be divided into splint crusher and box crushersource of reference: network crushing hammer
The main user name is lazy. Founder of Peking University Weiming station. After resigning in September 2001, he no longer participated in the station affairs management. Later, he was invited to continue to write code for Weiming BBS
yanglc, the most important technical station of Peking University Weiming station. Since taking office in September 2001, the company has maintained the normal operation of Weiming BBS for more than two years with one person until the beginning of 2004. No one has written more code for anonymous. It is said that when he was in office, he worked for Weiming for more than ten hours a day
Alessa, thdhys and Jarlaxle are the authors of Peking University's famous original RPG game biography of Peking University and the sequel biography of Peking University. The themes and characters of their works are partly taken from the stories of Peking University Weiming, and are widely spread in Peking University through Weiming. Among them, Alessa is a native of Nanchong, Sichuan Province, with a bachelor's degree of 04 in German Department of Peking University; Thdhys is a native of Tianjin, with a bachelor's degree of 04 and a master's degree of 08 in Peking University School of physics; Jarlaxle is a native of Changchun, Jilin Province, with a bachelor degree of grade 04 in Peking University
influential people
the famous people in Peking University may be the most noteworthy people on BBS, so it is necessary to give some examples. In order to avoid ranking disputes, the following is listed in the order of Latin alphabet and Chinese Pinyin:
Chievo, trying to keep up with yxtgh, once published a lot of news in the triangle every day. However, unlike yxtgh, which only publishes news but does not "irrigate water", Chievo also publishes a large number of "hydrologic" content unrelated to news on the whole station, which is jokingly called "the second generation news robot" because it "looks more intelligent". He is a 04 undergraate student in the Department of mathematics of Peking University and a master's degree student of grade 08. When he was in school, he was in charge of the football edition and so on. He has rarely published news
chuatu, whose main ID is tryto / Liubei, used to be the most famous one among the new generation of water tankers, grade 04 of Beida law school, Miao nationality. The number of irrigation words is usually no more than 10 words, and the whole station is flooded. Present no mm hungry state, is the station once the most affinity of a waterwheel. Although he has graated and left school to work in the south, he was still active on BBS and remembered by countless mm. The head picture is a cute little rabbit, and the level is the "chuatu" he proposed to set. The number of articles published exceeds 200000, which is the first waterwheel of Peking University's Weiming BBS. After the declaration of retirement, now rarely on the station, now in Guizhou Province as a village official. Recently, however, it has returned to the trend of irrigation in Weiming
photon, full name of union photon, also known as photon mm, was originally called uniphoton, and later mainly Glazer / Lazard / HenryFord, from Haikou, Hainan. When photonics was still in middle school, it became famous on the BBS such as ytht, BDWM and Tianya virtual community; On BDWM, I like to publish original articles on politics, finance, economy, foreign affairs, science and technology, national defense and other topics in many academic pages, and cause disputes. Because he often publishes articles that are meaningless and easy to cause controversy (that is, constitute "digging" behavior) in the triangle, although his writing is fluent and imaginative, he is often criticized and even banned severely. Even the user name of uniphone is included in the list of permanent prohibition after being punished by deleting users. One semester before graation, photonics mainly published some original posts about financial investment in the stock edition of three districts and various digging posts in the history edition, but rarely replied to other people's theme posts. After graation, photons have rarely visited the unnamed BBS, and there are almost no new articles in the triangle. He is a 03 undergraate of Guanghua School of management at Peking University and currently works in Shanghai
HAOGE, whose main user name is cyberia / Stavros, etc. As a technical and permanent station manager, he often participates in discussions related to the development of BBS software and hardware systems, and is very concerned about the future of Peking University. However, some important reforms and decisions sometimes lack consultation with other station management members, and he is sometimes accused of abusing his technical advantages to interfere in administrative management, During the period of Joke edition, all the articles that had been tagged were deleted one day after being not communicated with other editions. Although the layout of the articles was backed up in the essence area, they were still subjected to the ties and impeachment of the netizens.
Hydralisk III / Hydralisk and bieuyige / happy pavilion, the latter is a club layout created by the former. Because many members of the club are or later become station and district affairs, it is known as "the back garden of unnamed management". At the beginning of its establishment, it was named hydrahome, and the Chinese name of the page is said to have been given by netizen Aile. This edition mainly focuses on irrigation, and sometimes there are some activities such as edition killing. The atmosphere of the page is relaxed and active, and the snake is also known as the snake mm or CSMM. This edition also compiles a "happy pavilion dictionary", most of which refer to some behaviors and characteristics by the ID of friends. He is a native of Tianjin. He graated from the Department of computer science, Peking University. After graation, he studied in the University of San Francisco and worked in Beijing after obtaining a master's degree
Kama, whose main user name is KarlMarx, is from Yancheng, Jiangsu Province. In the early days, similar to United photonics, he liked to "dig holes" in the triangle, publish some controversial topics, and pay attention to current affairs. For a long time, he insisted on daily reprinting "today in history" in the triangle. Later, he seldom argued seriously with others, and his words were relatively mild. In addition, he insisted on "teasing" every "little mm" in many pages for a long time, so he was also welcomed by many ordinary users. He is an undergraate in the Department of electronics and a graate in the school of international relations at Peking University
Kelly, usually called sister orange, once ID yujioda, is the most dazzling one of the new generation of beautiful water tankers. She is very popular in Weiming. She is from Sichuan Province, and she is a Bachelor of grade 07 of Peking University. Because of her sweet and lovely appearance, she is quite like a girl next door. In addition, she is lively and cheerful, and dares to love and hate. Many Peking University boys like her very much and compare her to Peking University's "pure beauty". But it seems that she is single, so some netizens think her character and emotional experience are more similar to Ye Shannan. Orange has a strong interest in many fields other than learning, and is rated as the football version flower for her rare profound football knowledge among girls. She is also one of the unknown celebrities
Nash, whose main user name is globalnash / football, is from Beijing. School of foreign languages, Peking University, grade 02. Beida Weiming is a famous fat man and rich man. He is the founder of Xinxin DIY club in Pacific Electronics Market and one of the suppliers of Weiming hardware equipment. Nash is famous for its fierce and unreasonable management style, so it is often applied for arbitration by ordinary users. He is still running Shenshen club, which has not been affected by the 2008 economic crisis
queen refers to lovefaye / sleepy catpig / shmilyfu or lovefaye among them. All of them were once students of Peking University nursing college. They were named "Queen" only because they were female students but their words were "tough" and "strong". Lovefaye is the most outstanding one among the three. For a time, lovefaye often published articles on sex and reproction in the pages of joke, anonymous and medical department / HSC. Although it is academic, its words are too explicit. Therefore, lovefaye is often banned, and has aroused extensive discussion from the management of Weiming to ordinary users. Now "Queen" is also used to address other similar characters, such as ccup, smallchang, Evonne fan and so on. At present, lovefaye works in Beijing after studying in the UK, while the other two work directly in Beijing
Xiaoqiang, whose main user name is sq / Shenqiang, is from Jilin. Besides being young and senior, he is also famous for his legendary deeds. In Peking University, Xiaoqiang often participates in various intellectual problems and discussions about foreign language learning. He also likes to speak in languages that most users can't understand, such as Japanese, French, Portuguese, Spanish, etc. Xiaoqiang is good at using personal anthology. He used it to make a clever mud game, but he was punished for abusing the storage quota of anthology. The account sq was banned from sysop, guest, bmtest and other accounts in the killergame version, and published more than 300 screens of ASCII graphics "Tetris" in the blending version, so it was decided to kill the file after the discussion of the station affairs group. After the announcement was issued, it caused a heated controversy of the majority of waterwheel and strong dissatisfaction and query to the station regulations and station affairs group. This file killing decision was later withdrawn, and the version service and station management authority were revoked instead. He is currently working in Beijing. He is an undergraate of grade 00 in the school of Mathematical Sciences of Peking University. Later, he went to the Chinese Academy of Sciences for a master's degree
Xiaoxiao, the main user name is wnstanly (and smallchang are not the same person). The first "waterwheel" type senior user with more than 100000 articles was also called "God's man" in Hebei version because he was the first to show 10 points when he began to try the points system. He has been criticized for "watering" (Publishing too many chatting or meaningless articles)
the official name of sunshine pig should be the leader of yingguixuan. Sunshine pig and moonlight fairy are derived from the ID ygxz. The main user name is ygxz / RS, etc. Sunshine pig is famous for its obsession with BBS life in the closed mess and Beida Weiming. In 2005, the number of articles published by Yangguang Xiaozhu exceeded Xiaoxiao, becoming the largest number of users in the history of Beida Weiming at that time. In 2006, it faded out of Peking University. At present, ygxz has more than 170000 single ID documents, second only to tryto. He is a 2002 undergraate of Guanghua School of management, Peking University. He is from Zaozhuang, Shandong Province. He is now starting a business in Beijing< br />yxtgh The students of multiple, the former head of Weiming District 8, reprint all kinds of news from mainstream network media to Weiming's various pages, which are mainly based on triangle, all day long, which makes it convenient for users to obtain news information and also attracts criticism. Many people think that his reprinting behavior narrows the eyes of most anonymous users to obtain external information through reading Internet news reports. Some people believe that this user is not a natural person, but an automatic robot controlled by the "superior", or even a robot script written by HAOGE. Around this problem, we often discuss whether this ID is a robot. After many statements, we have banned such discussion. He is currently moving to Japan, where he works. Recently, e to the company's distribution, he returned to the Beijing Branch
public figures
there are some public figures who enjoy high popularity in the society outside the campus, such as sports stars, performing stars, etc. for various reasons, they may also appear in Peking University's unnamed BBS. Although most of them rarely show up, some still attract the attention of other users. Here are the following people who can be sure of their identity:
Zhang Peixiang, whose user name is flyingflower. Network writer, representative works "sell rice", "Dahua Honglou" and so on. He died of leukemia in July 2003
staff of Peking University
many teachers and staff of Peking University also log in to Peking University's unnamed BBS, but few of them actively participate in "irrigation" and communicate with students. The following are listed here:
Marquis Wen (the Marquis of Lu Bu in the Eastern Han Dynasty), whose user name is Wenhou. Teacher of chemistry college, real name Huang Jianbin. Mr. Huang not only plays with the students of the chemical college volleyball team, but also "irrigates water" with everyone on BBS, and even takes up the post of "the other side of the dream / dream"

I signed this girl some time ago, and I wrote such a et work, so I talked about the cooperation of this song. After listening to the demo for two nights, I felt that the voice temperament was pretty good. Besides, we could talk all the time, and the cooperation would be more pleasant. So the work started in an orderly way. This song was revised four times just by arranging music, and I also demonstrated and recorded three versions of the demo. It's true that there are many female singers with better singing skills than he Manting, but everyone has made a little progress. The music instry is the same as any other instry. When you have been in a position for a long time and a new graate is transferred to take over your class, do you choose to share some work experience with him or stay away from him to prevent him from surpassing you? This is a matter of mentality. In addition, I haven't seen any of Xiao He. The recording was done in both places and then mixed by me. "

exe network business card 1. EXE file executable program is an executable program that can float in the storage space of the operating system. In MS-DOS and MS-Windows, the extension of this kind of file is. Exe 2. The binary executable file in Windows operating system. There are two kinds of executable files. One is named. Com, the other is. Exe. [ In MS-DOS, the file extension is used to identify the executable file. After the user enters the file name without. Exe extension in the prompt line, press enter to run the executable program. 2. EXE file structure. Exe files are complex, and each EXE file has a header, The structure is as follows:
EXE file header information
--------------------------------
├ offset ᥤ meaning ᥤ
├ 00h-01h ᥤ MZ & # 39; Exe file mark Ⅻ
Ⅻ 02h-03h Ⅻ remainder of file length divided by 512 Ⅻ
Ⅻ 04h-05h Ⅻ quotient Ⅻ
Ⅻ 06h-07h Ⅻ number of relocation items Ⅻ
Ⅻ 08h-09h Ⅻ quotient of file header divided by 16 Ⅻ

. EXE file contains a header and A relocatable program image. The header contains the information MS-DOS uses to load the program, such as the size of the program and the initial value of the register. The header also points to a relocation table that contains a list of pointers to the addresses of relocatable segments in the program image. The form of the file header corresponds to the exeleader structure:
exeleader structure
exsignature DW 5a4dh Exe flag
exrabytes DW; The number of bytes in the last (partial) page
expages DW; All and some pages in the file
exreloctitems DW; The number of pointers in relocation table
exheadersize DW; File header size in bytes
exminalloc DW; Minimum allocation size
exmaxalloc DW; Maximum allocation size
exinitss DW; Initial SS value
exinitsp DW; Initial SP value
exchechsum DW; Complement check value
exinitip DW; Initial IP value
exinitcs DW; Initial CS value
exreloctable DW; The byte offset of relocation table is
exoverlay DW; The overlay number
exehead ends program image contains the initial data of processor code and program, immediately after the file header. Its size, in bytes, is equal to the size of the. EXE file minus the size of the file header, and is also equal to the value of the field of exheadersize multiplied by 16. MS-DOS copies the image directly from the file to the memory to load the.EXE program and adjusts the relocatable segment address specified in the location table.
the location table is an array of relocation pointers, each pointing to the relocatable segment address in the program image. The exreloctitems field in the file header indicates the number of pointers in the array, and the exreloctable field indicates the starting file offset of the allocation table. Each relocation pointer consists of two 16 bit values: offset and segment value. To load the. Exe program, MS-DOS first reads the file header to determine the. Exe flag and calculate the size of the program image. Then it tries to apply for memory. First, it calculates the sum of the size of the program image file plus the size of the PSP plus the memory size specified by the exminalloc field in the exehead structure, if the sum exceeds the size of the maximum available memory block. Then MS-DOS stops the loader and returns an error value. Otherwise, it calculates the sum of the size of the program image plus the size of the PSP plus the memory size specified by the exmaxalloc field in the exehead structure. If the second sum is less than the size of the maximum available memory block, MS-DOS allocates the calculated amount of memory. Otherwise, it allocates the maximum available memory block. After allocating the memory, MS-DOS determines the segment address, also known as the starting segment address, from which MS-DOS loads the program image. If the values in exminalloc and exmaxalloc fields are both zero, MS-DOS loads the image to the highest end of memory as much as possible. Otherwise, it loads the image next to the PSP domain. Next, MS-DOS reads the entries in the relocation table and adjusts all the segment addresses specified by the relocatable pointer. For each pointer in the relocation table, MS-DOS looks for the corresponding relocatable segment address in the program image and adds the starting segment address to it. Once the adjustment is completed, the segment address points to the code and data segments of the loaded program in memory. MS-DOS builds a 256 byte PSP in the lowest part of the allocated memory, and sets Al and ah to the values set when loading the. Com program. MS-DOS uses the value in the file header to set SP and SS, adjust the initial value of SS, and add the starting address to it. Finally, MS-DOS reads the initial values of CS and IP from the program file header, adds the initial segment address to CS, and transfers the control to the program at the adjusted address[ Three EXE file format DOS executable file: the simplest executable file format, can be run in dos and windows. It is identified by adding the ascii string "MZ" (4d5a in hexadecimal) to the file header“ "MZ" is the acronym of mark zbikowski, one of the developers of MS-DOS
16 bit new executable file: identified by adding the ascii string "ne" to the file header. It can only run on windows and OS / 2 system, but not on DOS
16 / 32-bit hybrid linear executable: identified by adding the ascii string "Le" to the file header. It is only used to replace VxD driver in windows 3. X and Windows 9x
32-bit linear executable: identified by adding the ascii string "LX" to the file header. Running in OS / 2 2.0 and later, it can also be used for some dos extensions
32-bit executable file: This is the most complex and popular executable file format. It is identified by adding the ascii string "PE" to the file header. It mainly runs in Windows 95, Windows NT and later versions of windows, and it can also run in beos R3
64 bit executable file: similar to the former, but with 64 bit CPU. Therefore, it can only run in 64 bit windows system, such as Windows XP 64 bit edition and Windows Server 2003 64 bit edition.
