Question 3: How to write the keywords and abstract in the paper? The abstract of a paper is generally about 100 to 200 words, and a large paper (such as a graduation thesis of 40,000 to 50,000 words) can also be about one page (700 to 800 words). It should explain what problem the paper aims to solve (i.e., its significance), Method, if there is an experiment, explain the basic method of the experiment, one to several conclusions drawn under the conditions of the research, and the last sentence summarizes the conclusion and generalization significance of the conclusion in a given scope of application. For example, something under a certain condition is very important, but the accuracy of measuring a certain parameter under a certain condition is not high. This article uses a certain method to measure a certain result under a certain condition. How accurate is it, within a certain limited range? What effects can this method have? Keywords must be content words. They are generally used to summarize one or more fields that your paper covers, as well as the research methods that you think are important. For example, the keywords of a paper about water treatment can be: drinking water, ultraviolet disinfection, and organic matter. This is fine. Of course, the specific wording involves the content of your paper.

The keywords of scientific papers are words or phrases selected from the title, hierarchical headings and text that can reflect the theme concept of the paper. Keywords are proposed to meet the needs of computer retrieval, and are placed after the abstract. As early as 1963, starting from Volume 58 of Chemical Abstracts in the United States, electronic computers were used to compile keyword indexes to provide a way to quickly retrieve the subject of literature materials. Today, with the rapid development of science and technology information, hundreds of thousands of scientific and technological papers are published every day around the world. The academic community has long agreed to use subject concept words to search for the latest published papers. If the author publishes papers without tagging keywords or descriptors, the literature database will not include such articles, and readers will not be able to search them. Whether the keywords are selected appropriately is related to the retrieval of the article and the utilization rate of the results. 1 Keyword classification Keywords include descriptors and free words. ? 1) Descriptors - refer to standardized words or phrases that are included in vocabulary lists such as "Chinese Thesaurus" and "MeSH" and can be used to index the subject concepts of documents. 2) Free words - newly created nouns and terms that reflect new technologies and new disciplines in the topic of the paper that have not been included in the thesaurus or words that cannot be found in the thesaurus. 2 Keyword Indexing In order to meet the needs of automatic computer retrieval, GB/T 3179-92 stipulates that modern scientific and technological journals should give 3 to 8 keywords (or descriptors) after the abstract of academic papers. The indexing of keywords should be based on the principles and methods of GB/T 3860-1995 "Document Thesaurus Indexing Rules" and selected with reference to various glossaries and reference books; important new disciplines and new technologies that are not included in the glossary Terminology, names of people and places in the title of the article can also be marked as keywords (free words). The so-called indexing refers to the process of subject analysis of documents and certain features with retrieval significance, such as research objects, processing methods and experimental equipment, and using the subject vocabulary to provide subject retrieval identifiers. The purpose of subject analysis of documents is to find out the basic elements that constitute the subject of the document from the document with complex content, so as to accurately index the required descriptors. Indexing is the prerequisite for retrieval. Without correct indexing, correct retrieval is impossible. Scientific papers should index keywords according to the descriptor indexing method, and standardize free words into descriptors as much as possible.

3 Basic principles that should be followed when indexing keywords 3.1 Principle of specificity A word can only express one topic concept, which is specificity. As long as the corresponding specific thesaurus is found in the thesaurus, the use of hypernyms (S items) or hyponyms (F items) in the thesaurus is not allowed; if no thesaurus directly corresponding to the subject concept is found, If the hypernym is indeed consistent with the theme concept, it can be selected. For example: "Aircraft fire protection" can find the corresponding specific word "special aircraft fire protection" in the thesaurus, so it must be selected first. The hypernym "fire prevention" shall not be used for indexing, nor shall the two subject phrases "aircraft" and "fire prevention" be used for indexing. ? 3.2 Principles of combination The combination of descriptors should be the combination of concepts. Concept combinations include 2 types: Cross combinations. Refers to 2 or 2...gt;gt;

Question 4: What does the iron stream mean? The iron stream refers to our dear and lovely *** soldiers, and we call them They are Tieliu because they have an iron will, and no hardships or obstacles can destroy them.

Problem 5: If the roof is broken, it is easy for the roof to fall off. The roof is very hard and difficult to fall off when the roof is lifted. It often destroys the coal mining face. What does this sentence mean? This means that once the roof is broken, it is easy to fall, but generally the roof will be pressed periodically. After the pressure is applied, the roof will crack. At this time, a large area will collapse, and the falling stones will crush the working surface. . .

Question 6: What is joint fire strike? Two or more military services use long-range firepower as the basic means to attack the enemy's combat system and other important targets. It is the main means of combat in high-tech local wars. Usually, the long-range precision strike force of various services and arms is mainly organized and implemented by comprehensively using information attacks, missile attacks, air assaults, special sabotage and space support and other means and methods. It has the characteristics of "non-contact operations". The purpose is to carry out sudden and violent firepower assaults on important targets in the enemy's combat system to weaken its military strength and war potential, destroy its will to resist, and create favorable conditions for subsequent operations. In the 1991 Gulf War and several subsequent modern local wars, the U.S. military has used joint firepower strikes as an important combat method to win the war.

Question 7: What does it mean that if Qin is destroyed, Chu must be destroyed? "If Qin is destroyed, Chu must be destroyed" means: Chu State will definitely destroy Qin State.

The Qin State was eventually destroyed by the Chu people. Chen Sheng, Xiang Yu, and Liu Bang were all Chu people.

"Although Chu has three households, if Qin is destroyed by Chu," this famous saying originated from the era of resistance to the violent Qin rule. It comes from "Historical Records of Xiang Yu" written by Sima Qian in the Western Han Dynasty. This means that even if there are only a few families left in Chu State, Qin State can still be destroyed. Although the metaphor is small, success can still be achieved with great determination. It represents an emotionally charged belief.

Regarding the national uprising that overthrew the rule of the Qin Dynasty, its historical materials are mainly recorded in "Historical Records", especially "The Chronicles of Xiang Yu", "The Chronicles of Gaozu", "The Moon Between Qin and Chu", " "The Chen She Family", "The Biography of Zhang Er and Chen Yu", "The Biography of Tian Dan", etc. are the most detailed. Hai was the first advocate of anti-Qin, and Chen Sheng's historical achievements were fully recognized at that time and in later generations. However, his fighting spirit and unswerving anti-Qin belief have not been clearly identified accordingly.

After Chen Sheng's death, the anti-Qin war took a turn for the worse. The Qin army led by Zhang Han was invincible with Lien Zhan and Lianjie, and the great cause of anti-Qin was about to be ruined. On this occasion, Xiang Liang, a native of Chu, accepted Chen Sheng's seal and led his troops across the Huaihe River, and incorporated Chen Ying, Qing Bu, Lu Chen, Liu Bang and other armies. In order to show that he was Chen Sheng's orthodoxy, Xiang Liang killed the Jingju tribe of Qin Jia, who was known as the king of Chu, and established Sun Xin, the king of Chu Huai, as king of Chu Huai. At that time, Chu's power was much inferior to that of Chen Sheng's heyday, but under the leadership of Xiang Liang, he actively sought to fight the main force of the Qin army. Soon, they defeated the Qin army in Dong'e (now northeast of Yanggu, Shandong), Chengyang (now northeast of Heze, Shandong), Puyang, Yongqiu (now Qixian, Henan) and other places, defeating the Qin army's arrogance. Due to the unstoppable momentum since his departure, Xiang Liang developed the paralyzing thought of underestimating the enemy and was defeated and killed by the reinforced Qin army. King Huai of Chu gathered the troops of Xiang Yu, Liu Bang, and Lu Chen and redeployed them to fight against Qin. At that time, Zhang Han, the commander-in-chief of the Qin army, thought that since Xiang Liang was defeated, Chu had nothing to worry about, so he moved his army to attack Zhao.

As a result, Julu in Zhaodi (now Pingxiang, Hebei) became the main battlefield in the war against Qin. After Xiang Liang's defeat, Chu's power was greatly weakened. Despite this, King Huai of Chu still drove his troops to the battlefield for a decisive battle with Qin: the main force of the Chu army was led by Song Yi to Zhao Chi for reinforcements, and the other branch was led by Liu Bang to the west to attack Qin. Judging from this move, Sima Qian was very far-sighted in putting Chen Sheng's career in place until Xiang Liang established Chu Huaiwang's heart.[9] This also fully proves that the Chu established by the Xiang family is indeed the legal basis of Chen Sheng's spirit and career. It was this decision made with the heart of the king that officially kicked off the destruction of Qin.

Originally Xiang Yu planned to march westward with Liu Bang to destroy Qin and avenge Qin for killing his uncle Xiang Liang, but King Huai refused. Xiang Yu was appointed as Song Yi's deputy and accompanied the army to rescue Zhao. Frightened by the power of the Qin army, Chu commander Song Yi stayed in Anyang (now southeast of Caoxian County, Shandong) for 46 days to avoid contact with the Qin army. Xiang Yu killed Song Yi and led the Chu army to the battlefield with Qin. Facing the Qin army that was gaining momentum, not only the princes supporting Zhao from all walks of life did not dare to use troops rashly, but even Zhao's own peripheral troops such as Chen Yu, Zhang Ao and other troops did not move. Only the Chu army, under the leadership of Xiang Yu, shared the same hatred with the enemy and without hesitation entered into a fight that would determine the fate of the world. In the battle, the Chu army fought bravely and skillfully, one against ten, and finally defeated Qin under the giant deer. Not only did it defeat the Qin army, but it also brought all the princes to their side. From then on, Xiang Yu, as the commander-in-chief of the coalition of princes, sent troops to pursue the Qin army and continued to win. In the end, the coalition forces completely destroyed the Qin army's fighting spirit in the Sanhushui area, and the main force of the Qin army surrendered to the coalition forces in July of the third year of Qin II. Without the bloody battle of the Chu army, and without Xiang Yu's decisiveness and good command, the victory of aiding Zhao and the overthrow of Qin would have been unimaginable.

Liu Bang's westward advance also showed Chu's determination to subjugate Qin. "The Chronicles of the Great Ancestor" records: "At that time, the Qin army was strong and often took advantage of the victory to drive north. The generals Mo Li entered the pass first." This shows that the move to the west is a risky move that is divorced from reality. With the main strategic goal of aiding Zhao, the number of troops Liu Bang led was extremely limited. For this reason, King Huai of Chu granted Liu Bang the authority to "acquire the scattered soldiers of King Chen and Xiang Liang". This is tantamount to letting Liu Bang try to solve the problem of troop sources by himself. The situation Liu Bang faced was to fight away from the base area, and his fighting method was to fight and go. The situation is similar to that of Zhou Wen's tribe during Chen Sheng's period, except that its strength is much inferior, and the vigilance and combat effectiveness of the enemies it faces are greater than those encountered by Zhou Wen. But these difficulties failed to scare Liu Bang and his troops. They marched westward with the Chu army's customary arduous spirit and determination to defeat Qin. The westward march did not go well. Liu Bang's troops won some battles, but also encountered some difficult enemies and difficult-to-attack cities. For example, several strategic locations such as Changyi (now northwest of Jinxiang, Shandong), Kaifeng, and Luoyang were not captured. In this case, heading west...gt;gt;

Question 8: What does centipede mean? Centipede: a multi-jointed and multi-legged reptile, ① another name for millipede. The body is long and slightly flat, more than an inch long, and is composed of many links, each of which has one or two pairs. Broken into two pieces, the head and tail can still walk independently. It is often used to describe the homeland, old home, or a person with a powerful position. ②The common name of centipede.

Example: Gao Yang's "The Complete Biography of Hu Xueyan? The Red Top Merchant": "I also know that the Songjiang Cao Gang is '~, dead but not dead' and unwilling to cause trouble."

Usage: as object and attributive; to describe bad forces.

Question 9: There is a popular saying on the Internet now, what does it mean to doubt life? Why doubt life? Because: Time wrinkles the skin, but old age can wrinkle the soul. Worry, fear, and even self-doubt can destroy the spirit and damage the vitality! However, listen to the motto of former US President Clinton: Youth is not a period of life, but a state of mind. Youth Inspiration - Clinton's motto Youth is not a period of life, but a state of mind. The essence of youth is not pink face and rosy cheeks, red lips and flexible joints, but firm will, rich imagination, full emotions, and a trace of coolness rippling in the sweet spring of life.

The connotation of youth is the courage to overcome cowardice and the spirit of daring to take risks, rather than being indolent. Many sixty-year-olds have more of this quality than twenty-year-olds. Although we are getting older, we are not aging; the cause of aging is giving up the pursuit of ideals! There is a radio station in each of us, and we have youth as long as we receive messages of beauty, hope, joy, courage, and strength from others and from the Creator. Once the antenna collapses, the spirit will be suppressed by the frost of cynicism and joy and sorrow. At this time, even a 20-year-old person will feel old. However, as long as the antenna is raised high and the optimistic radio waves are continuously received, then, Even if you are over 80 years old, you will still feel young.
