1. Go to the coal mine technology forum and ask
2. If the shearer can't be adjusted up or down, it must be caused by its lack of pressure or hydraulic pipe line.
3. In the 21st century, the whole world is calling for peace, so civil defense seems to be far away from us. In fact, civil defense is around us, and it needs our attention and attention
civil defense is an activity in which the government mobilizes and organizes the masses, takes anti air raid and disaster relief measures, carries out rescue operations, and prevents and reces disaster hazards. The purpose of civil defense is to protect the civilian population from harm, to help the civilian population overcome the direct effects of hostile actions or disasters, and to provide some or all of the following humanitarian tasks for the survival of the civilian population
leaders of all dynasties have made important expositions on the work of civil air defense, and the great Chairman Mao said; Digging deep, accumulating grain extensively, not seeking hegemony;, Deng Xiaoping, who founded and developed the theory of socialism with Chinese characteristics, once said; Civil air defense fortifications should be combined with peacetime and wartime, so that they can be reliable;. It can be seen that civil defense is closely related to the people and the country
we are the hope of our motherland tomorrow, but what can we do for civil defense? Protect your life. Only when we protect our lives can we be qualified to defend our country and our people. Therefore, the current primary and secondary school students should do their best to prevent and rece disasters and rece accidental casualties, so as to make some contributions to the strength of the motherland
in order to make the people understand and attach importance to civil defense, civil defense departments at all levels are making unremitting efforts to develop civil defense cause, actively organizing and carrying out civil defense ecation, so as to enhance the national defense concept and carry forward patriotic enthusiasm. I am glad for the progress of the civil air defense cause of our country. I am deeply worried about the phenomenon of ignoring the civil air defense work that still exists. I am deeply sorry for the indivial acts of damaging the civil air defense project. Today's world situation, peace and development has become the theme of the times, scientific and technological progress is changing with each passing day, and world multipolarization and economic globalization are highlighted. But at the same time, hegemonism is competing fiercely, regional hot spots emerge in endlessly, and there is still the danger of war. Therefore, our thoughts must always be highly vigilant, and we must unswervingly implement the strategic policy of "based on combat readiness, facing the market, combining peacetime with wartime, and developing civil air defense", implement the principle of coordinated development with economic construction and combining with urban construction, and strive to play a greater role in urban construction and urban management
I clearly remember such a sentence: "we should learn and love civil air defense, because loving civil air defense means loving national defense, and loving national defense means loving the motherland.". Whether a country is strong or not depends on whether its sovereignty is strong or not. If we want to have a strong sovereignty, we must have a strong national defense force as the backing. In today's society, some countries rely on powerful national defense forces to bully the weak, wantonly interfere in other countries' internal affairs and practice hegemonism, which is enough to show that national defense forces are an important standard to judge whether a country is strong or not
to actively do a good job in civil defense is to accumulate strength for the country, rece the burden of the motherland in the war, and provide reserve forces. We should make unremitting efforts to develop civil air defense to ensure the smooth progress of the socialist modernization of the motherland.

Civil air defense (civil defense in foreign countries) is an important part of the Ministry of national defense and a long-term nationwide combat readiness work
it is an important strategic measure to prevent the enemy's sudden attack, protect the safety of people's lives and property, rece the loss of national economy, effectively preserve the war potential, and win the future anti aggression war
Young people are the future and hope of our country. It is the bounden ty of our civil air defense teachers to improve their national defense concept and air defense awareness. In recent years, Yao'an County People's Air Defense Office attaches great importance to the ecation of civil air defense knowledge in primary and secondary schools. It is the mission of the civil air defense law of the people's Republic of China to carry out civil air defense knowledge ecation for primary and secondary school students in the new situation, the important content of strengthening civil air defense construction in peacetime, and the important aspect of comprehensively improving the comprehensive quality of primary and secondary school students. In the process of carrying out civil air defense knowledge ecation in primary and secondary schools, we proceed from the objective reality, conscientiously implement the provisions of the higher authorities on strengthening civil air defense knowledge ecation for primary and secondary school students, and take effective measures, so as to improve the quality of civil air defense knowledge ecation in primary and secondary schools in our county Civil air defense refers to the measures and actions taken by the government to mobilize and organize the people to guard against enemy air attacks and eliminate the consequences. It is an important part of modern national defense, an important aspect of national economy and social development, an important content of modern urban construction, and a social public welfare undertaking beneficial to the country and the people5. In recent years, with the rapid development of economic construction and the accelerated pace of urban construction, people have ignored the organic combination of urban construction and civil air defense. When building houses, they don't pay attention to the construction of underground air defense facilities, especially the construction of middle school houses. There are basically no air defense facilities. Students have little awareness of civil air defense, Not even at all. Although it is a time of peace, it is necessary to strengthen civil air defense ecation in urban middle schools. In order to strengthen civil air defense ecation in urban middle schools, we should mainly focus on the following aspects:
first, we should take national defense ecation in middle schools as an opportunity to promote civil air defense ecation. Civil air defense is an important part of national defense. Civil air defense ecation should be combined with national defense ecation. Middle school teachers should integrate civil air defense ecation with national defense knowledge ecation, consciously put civil air defense ecation into national defense ecation, and strive to make students realize that a country can't have no defense for a day, and a strong country can ensure the safety of the people. In this way, the status and role of civil air defense can be recognized and understood by students. Teachers can also make use of the specific sensibility of national defense and students' closer understanding of national defense to carry out civil air defense teaching, which can not only expand students' knowledge, but also stimulate students' interest in learning. The national defense awareness and civil air defense concept of the future generation of the motherland will be further enhanced, and at the same time, it can stimulate students' patriotic enthusiasm
the second is to adhere to the combination of theoretical ecation and practical practice. It is of great strategic significance to strengthen the civil air defense ecation in middle schools. At the same time, it is also of great practical significance to strengthen students' practical exercises. Cities with conditions can make use of the air raid shelters ring the Anti Japanese War to increase the students' practical exercises of evacuation, escape and rescue, which not only breaks through the limitations of classroom teaching, but also improves the students' practical ability of applying what they have learned. It can also use the air defense basement of the building near the city to carry out the hidden evacuation exercise, and carry out the actual civil air defense exercise, so that students can get a real feeling< The third is to strengthen civil air defense knowledge ecation while carrying out civil air defense knowledge ecation. Today's middle school students have never experienced the smoke of war. The war is too far away from them. Even if there is a war like Iraq, it is difficult to narrow the distance and reality between the war and the students. Therefore, it is necessary to combine the fire fighting and escape, electric shock and emergency rescue, non meteorological disasters and emergency evacuation in civil defense ecation to teach students the protection knowledge and self-help and mutual rescue skills often used in daily life, improve students' interest in civil defense knowledge learning, enrich students' civil defense teaching content, and make the original simple textbook knowledge learning, Become practical knowledge closely related to students' life and family< The fourth is to actively carry out the work of civil air defense into the community and promote civil air defense ecation. Students can not live without the community. They are students at school and community residents at home. In view of this characteristic, we can try to carry out various forms of "civil air defense knowledge into the community" ecation activities in the community, consolidate and strengthen the classroom content of middle school students while ecating the community residents on the concept of national defense and civil air defense awareness. At the same time, we can use the city to carry out the anti air raid alarm trial exercise, enhance the students' basic skills of escape and self-help in the face of emergency, and promote the civil air defense ecation.

6. Today, our school organized all the fourth grade students to conct civil defense ecation in Fengxian District< When we arrived at the "base area", we found that there were so many exercises! There are so many "building escape", "road for the brave", "fire drill", "drowning self rescue" and so on. I think the most interesting thing is "the road of the brave"
some props on the road of the brave are very exciting, we all want to play. When a PLA uncle said to play for us, we immediately cheered. The PLA uncle also said that if the first person to cross the equipment and reach the destination, he is the winner. We can't wait for our uncle to give us orders. Uncle a command, we immediately action, I grab in the front, first over the "rolling wood", and then stomp on the small attic, through the small suspension bridge, climb down from the chain, and then run to the next target with the fastest speed - crawl
crawling is the most difficult joint. At first, I grabbed the net rope to climb up, but I couldn't do it as soon as I got to the flat slope. The hole in the net woven with the rope was very big. If I walked upright, it was easy to step into the big hole, so I had to climb slowly. Finally, I got to xiapo. Hey, Zhang Keqi was a few steps faster than me. I climbed down in a hurry. I couldn't help stepping on Zhang Keqi's hand, and she stopped in pain, I took the opportunity to slip down, said sorry to her, and flew away
I come to the last goal - walking the tightrope. This seemingly difficult thing in the circus is actually very simple, because there are handrails on both sides of the steel wire! Hee hee. I walked cautiously through the wire and ran to the end. I won. Yeah
although "the road of the brave" is the most fun, "building escape" is not bad. The PLA uncle selected ten people in our class, including me. Uncle first helped me fasten my seat belt, put on my gloves and took me upstairs. The floor is very high. There is a thick rope tied to the handrail on the roof. After my uncle taught me how to grasp the rope and slide down the stairs, I began to act. I firmly grasped the rope, and when I slid down, my right hand graally relaxed, slowly slid down, and finally fell to the ground, I gave a long breath. The coach touched my head and praised my standard action
today's drill is not only fun and exciting, but also teaches us how to save ourselves in times of crisis and how to minimize the danger. Today's play is very happy and meaningful!

Second, you need to find a place to prevent stray bullets. The air raid shelter is OK, but the modern civil air defense project will only be provided to some people in wartime ~
the underground civil air defense project in Wuhan should be transformed into a shopping mall in peacetime, and open an emergency way to the three defense public in wartime Things~

8. Thoughts on preparing for civil air defense in times of peace For survival: self help and mutual help in a critical moment, building a defense line for information security, and defending important economic goals, each of which lasts about 20 minutes< It is reported that the National People's Defense Office attaches great importance to the science and art of this series of science and ecation films, and specially organized an expert group to review the film It took two years to create this novel. After 12 manuscript revisions and 5 film revisions, it was finally approved by the expert group
according to the creator, in order to avoid the stereotyped preaching of previous science and ecation films, "be prepared for civil air defense in times of peace" adopts the combination of narrative narration and scientific interpretation, which makes the whole film more vivid and interesting. So as to attract the audience to watch and popularize the knowledge of civil air defense< On September 16, the scientific and ecational film "preparing for civil air defense in times of safety" was successfully broadcast on the comprehensive channel, economic channel and urban channel of Lankao County TV station. At the same time, our county organized the centralized screening in schools, communities, factories and squares, which set off the climax of Lankao County's civil air defense publicity and ecation this autumn
in order to conscientiously implement the spirit of the notice of the state civil air defense office and the State Administration of press, publication, radio, film and television on the organization of watching the scientific and ecational film civil air defense in times of peace, Lankao County planned ahead of time and organized carefully according to the work requirements of the Henan Provincial Civil Air Defense Office, In July, we successfully completed the preparation work of ordering and broadcasting the screening right of "be prepared for civil air defense in times of peace"
since September, Lankao County has carried out a variety of civil air defense publicity and Ecation Month activities in combination with national defense ecation day, air defense alarm day, centralized training of civil air defense professional teams and chemical defense and emergency rescue drills. From September 12 to 17, the county civil air defense professional team and factory workers were organized in Kaifeng ronghua chemical plant to conct civil air defense training and chemical prevention and rescue drill, and organized to watch "prepare for civil air defense in times of safety".

red maple in autumn, golden osmanthus fragrance. A few days ago, the screening of the film science and ecation film "preparing for civil air defense in times of safety" and the centralized publicity and ecation activities of civil air defense are in full swing, and have been widely praised by the public< The word "air defense" has never been touched in my mind and I don't know its importance. Because I grew up in a stable age, without war and hardship, I could not understand the importance of air defense. But after reading the book civil air defense, I realized: Oh! It turns out that air defense is so important. It symbolizes the prosperity of a country and defends its dignity
as the name suggests, air defense for human life refers to the action of letting the people work together to prevent and eliminate the enemy's air attack, which is called air defense for short. Civil defense is the combination of wartime air defense and peacetime disaster relief that people participate in. Civil air defense and civil air defense are the core part of China's national defense, an important factor in promoting the development of modern construction, and an important cause for the whole people to participate in. Because air defense is a task that needs to be prepared at all times, "long-term preparation, key construction, and combination of peacetime and wartime" are the three-point projects of civil air defense< According to China's civil air defense regulations, the tasks of civil air defense are to mobilize and organize the people to take protective measures according to the characteristics of modern war, fight against the enemy's air attack, protect people's lives, avoid or rece the loss of national economy, and maintain the potential of war. Civil air defense must implement the construction policy of "comprehensive planning, highlighting key points, combining peacetime with wartime, quality first". It can be seen that civil air defense is an implementation plan that our country attaches great importance to. Civil air defense can bring peace and tranquility to our people
civil air defense is a long-term combat readiness task, because as long as imperialism and hegemonism are still there, the danger of war will not disappear. So we can't let the present moment of peace paralyze our thinking, and the people's preparation for war can't stop. Due to the development of modern science and technology, the lethal power of weapons is also increasing, and the damage to residents in the future war is bound to be greater and greater. Therefore, under the condition of modern war, strengthening the construction of civil air defense is the need of today's nuclear era, which has important strategic significance. So we should be prepared for danger in times of safety
now, I believe that as long as we cooperate with the national civil air defense construction. In the near future, our motherland must be the most powerful. We can not forget the humiliation, blood and tears ring the Anti Japanese War, which was the price of our blood and the difficulties and dangers when we remolded new China with our flesh and blood. Now, we should be prepared for the future of our country, so that we can be prepared
close the book, the four words of "civil air defense" have been deep in my heart for a long time. For the future of the motherland, in order to go to the top of the world, we should seriously study, do a good job as a country's future master, we also need to constantly innovate, constantly strong physique, let our motherland stand on the top of the world. I firmly believe that people will pay more and more attention to civil air defense, and the motherland will be increasingly prosperous and developed
please accept if you are satisfied.

LVM is the abbreviation of logical volume manager (LVM). It is a mechanism of disk partition management in Linux environment. It is implemented by Heinz mauelshagen on Linux 2.4 kernel. At present, the latest versions are: stable version 1.0.5, development version 1.1.0-rc2, and lvm2 development version. When Linux users install Linux operating system, a common problem that is difficult to decide is how to correctly evaluate the size of each partition to allocate appropriate hard disk space. When a logical partition can't store a file, the file can't be stored across multiple partitions because of the limitation of the upper file system, so it can't be placed on other disks at the same time. When a partition runs out of space, the solution is usually to use symbolic links, or use the tools to adjust the partition size, but this is only a temporary solution, not a fundamental solution. With the emergence of Linux logical volume management function, these problems are solved, users can easily adjust the size of each partition without downtime
