1. The relevant information was provided by OPP mining machinery. Because of the limitation of space, no compensation for low-level work-related injuries and space, I removed the content of Grade 10 rating. Instrial injury level identification standard is labor ability identification, which refers to the level identification of the degree of labor dysfunction and self-care disorder. Labor dysfunction can be divided into ten disability levels, the heaviest is level 1, and the lightest is level 10. There are three levels of self-care disorder: totally unable to take care of themselves, most unable to take care of themselves and some unable to take care of themselves. The standards for appraisal of labor capacity shall be formulated by the labor and social security administrative department of the State Council in conjunction with the health administrative department of the State Council

4. "About luck" I don't need any blood damage to prove the damage increased by luck, because there is also a problem of defense occurrence rate. The blood damage will not be the same. We can use Taoist's ghost shield to do experiments. My brother has a dish of luck plus 7 (186 bottles of oil!)+ Lucky plus 3 lantern (this is easier to do) now add up to lucky 10, you will find that his ghost shield is all the same number of seconds, all 276 seconds (this has something to do with his low Dao). This is his shield from the upper limit of Taoist art, which is the best proof. Also has played grandly should know the Rocha this grandly changes the weapon! Damage 15-0 unlimited curse to 10 when play 15-15 weapons, with the iris curse system equipment can play its power, this is also the best explanation of luck and curse
lucky algorithm: (upper weapon limit - lower weapon limit) × Lucky number × 10% and then add it to the lower limit of the weapon (the upper limit is positive and the lower limit is negative). This is the lower limit damage after the weapon is lucky, and the upper limit remains unchanged! For example, the algorithm of thunderbolt 8-34 luck plus 3 is (34-8) × three × 10% = 7.8, then the damage of thunderbolt is 15.8-34, that's it
curse algorithm: (lower weapon limit - upper weapon limit) × Curse number × 10% and then add it to the upper limit of the weapon (the higher the lower limit is a positive value and the higher the upper limit is a negative value). This is the upper limit destruction after the curse of the weapon. The lower limit remains unchanged! For example, the algorithm of thunder 8-34 curse plus 3 is (8-34) × three × 10% = - 7.8, then the damage after the thunder curse is 8-26.2, that's it
you must find that the algorithm of luck and curse is just the opposite! This has been confirmed by many people to be absolutely true! I hope you can have a better time with this formula
lucky algorithm: (upper weapon limit - lower weapon limit) × Lucky number × 10% and then add it to the lower limit of the weapon (the upper limit is positive and the lower limit is negative). This is the lower limit damage after the weapon is lucky, and the upper limit remains unchanged! For example, the algorithm of thunderbolt 8-34 luck plus 3 is (34-8) × three × 10% = 7.8, then the damage of thunderbolt is 15.8-34, that's it
curse algorithm: (lower weapon limit - upper weapon limit) × Curse number × 10% and then add it to the upper limit of the weapon (the higher the lower limit is a positive value and the higher the upper limit is a negative value). This is the upper limit destruction after the curse of the weapon. The lower limit remains unchanged! For example, the algorithm of thunder 8-34 curse plus 3 is (8-34) × three × 10% = - 7.8, then the damage after the thunder curse is 8-26.2, that's it
you must find that the algorithm of luck and curse is just the opposite! This has been confirmed by many people to be absolutely true! I hope you can have a better time with this formula

manual operation
import is generally more than two times of domestic Relatively weak, 2000-2500-3000 has high reliability
high degree of automation
from the perspective of instrial structure, domestic coal equipment enterprises are generally small in scale and scattered in layout, which means that superior enterprises will have greater comparative advantages in integrating the market, building supporting system, formulating instry standards, etc., and will be easier to stand out, And then grow into a coal equipment giant
from the perspective of equipment level, domestic coal equipment lags behind the international advanced level, and the indicators of equipment reliability, intelligence and informatization are obviously on the low side. However, in the past few years, domestic coal equipment has been continuously improved, and breakthroughs have been made in equipment manufacturing research and development, design and manufacturing
as a big coal country, the gap between domestic high-end coal mining machinery and foreign advanced level is narrowing in recent years, and the market share of domestic procts is also expanding. For example, the domestic hydraulic support market has a total market volume of 2 billion to 3 billion every year, of which the number of imported mechanical equipment is a relatively small part, and the vast majority are domestic equipment
the cost advantage provides domestic coal machinery manufacturers with strong competitiveness in the market. The average price is half cheaper than imported equipment, which is the reason why domestic coal machinery manufacturers can get sufficient orders in China. At the same time, China's coal machinery procts and manufacturers also have certain advantages over similar international companies in providing high-quality and perfect after-sales service, in-depth and detailed understanding of local customers' needs, and in the price and sales of accessories< br />5、 Ranking of domestic roadheader manufacturers

MD5 processes the input information in 512 bit packets, and each packet is divided into 16 32-bit sub packets. After a series of processing, the output of the algorithm is composed of four 32-bit packets, and a 128 bit hash value will be generated after cascading the four 32-bit packets
for messages less than 2 ^ 64 bits in length, SHA1 generates a 160 bit message digest. When a message is received, the message digest can be used to verify the integrity of the data
Thehash value is used as a unique value representing a fixed size of a large amount of data. A small change in the data can result in an unpredictable large number of changes in the hash value. The hash size of sha256 algorithm is 256 bits

extended data
the application of MD5 algorithm:
1, consistency verification
MD5 can proce an equally unique "digital fingerprint" for any file (regardless of its size, format and quantity). If anyone makes any changes to the file, Its MD5 value, that is, the corresponding "digital fingerprint", will change
MD5 algorithm is widely used in software download station, forum database, system file security and so on
2. The typical application of digital signature
MD5 is to generate fingerprint on a message (byte string) to prevent it from being "tampered"
for example, you can write a paragraph in a file called readme.txt, generate an MD5 value for the readme.txt and record it. Then you can spread the file to others. If others modify any content in the file, you will find that (the two MD5 values are not the same) when you recalculate MD5 for the file
if there is a third-party certification authority, MD5 can also prevent the "repudiation" of the file author, which is the so-called digital signature application
MD5 is also widely used in the login authentication of operating system, such as UNIX, login password of various BSD systems, digital signature and so on. For example, in UNIX system, the user's password is stored in the file system after hash operation with MD5 (or other similar algorithm)7.
