The influence of the earthquake disaster and earthquake disaster mitigation measures analysis

There are three main reasons for the earthquake hypothesis , namely “ elastic rebound ”, “the magma shock to say” ' said phase change.“These three hypotheses have some reasonable, but what causes earthquakes, pending further study

The Characteristics of earthquake disasterissudden and strong, destructive big , serious secondary disasters , far-reaching social , defense difficult.Sudden strong make it difficult to predict and the effect of prevention becomes weak.His devastating is to see, such as the Tangshan earthquake which caused 24.2 million deaths , injuries 16.4 million.The Secondary disasters such as fires , floods , tsunamis , landslides , mudslides , gas leaks, pandemics, radioactive contamination is also very scary.2004 Indian Ocean tsunami, which has razed to the ground in several cities.Due to sudden strong earthquake , suffered heavy casualties, huge economic losses , tend to produce a chain reaction , causing a huge impact on a region or even a social life and the country 's economic activity , resulting in a profound impact on society.Compared with floods, droughts, typhoons and other weather disasters , earthquake prediction is much more difficult.At the same time , improve the seismic performance of buildings , requires a lot of capital investment , this is not a short period of time can do.Although it is difficult to predict the devastating earthquake , but there is a history of China successfully predicted miracle.At 19:36 on February 4, 1975 occurred in Liaoning Haicheng earthquake prediction is accurate , which makes more than 100 million people in southern Liaoning Province promptly evacuated their homes and workplaces.This success is due to the abnormal situation in a timely manner to collect a large number of earthquake precursors , and timely induction, analyze, summarize the results , thanks to good policies of prevention group prevention and measured.Haicheng earthquake prediction can be successful, professional workers contributed to the earthquake, but it was the implementation of ”mass monitoring and prevention" approach, also played a crucial role.Generally speaking, professional workers in the earthquake, earthquake forecasting long, medium, and have a good chance, but the short-term forecasting, grasp not so big.The earthquake disaster prevention, the short-term forecasting truly decisive.References:

1).The nature of artistic merit is less easy to define than to recognize.The writer need

not even pursue it to attain it.2).The test in individual cases would seem to be one of enduring satisfaction and, ofcourse, truth.3).By embracing literary theory, we learn about literature, but importantly, we are also

taught tolerance for other people’s beliefs.4).Although each reader’s theory and methodology for arriving at a text’sinterpretation differs, sooner or later groups of readers and critics declare allegiance

to a similar core of beliefs and band together, thereby founding schools of criticism.5).“History teaching by example” is one phrase that describes this use of a study of the past — a

study not only of certifiable heroes, the great men and women of history who successfully

worked through moral dilemmas, but also of more ordinary people who provide lessons in

courage, diligence, or constructive protest.6.The same aesthetic and humanistic goals inspire people to immerse themselves in efforts to reconstruct quite remote pasts, far removed from immediate, present-day utility.The method of conceptual analysis might sometimes seem picky, but unclarity or imprecision in our concepts is often what leads us into paradoxes and incoherence in our world views.Every claim, no matter where it comes from, is subject to scrutiny.Even common sense is not taken for granted, which leads

philosophers to put forward some very weird views.7.8.翻譯來自第六單元的A課文

第四篇：英語學術(shù)演講稿

Good morning everyone.Welcome to my presentation.My name is …My major is mechanical engineering.The research direction of my team is the robot, so I’ll talk something about applications of the teleoperator robot in our life with two examples.The main contents of my speech are the medical robot and the cooking robot.First of all, we should know what teleoperator robot is.Teleoperator robots are mainly used for various operations of non-industrial production, for example, the medical robot, the cooking robot and the cleaning robot.Let’s first see the medical robot.The main characteristics of the medical robot is remote control.The remote control lets people stride across the space-time barrier.It means that the doctor and the patient can be in different places, as is shown in the pictures.The patient is in Strasbourg while the surgeon is in New York.The display screen provides surgery scene to the surgeon.By operating the main operation terminal and inputting commands, doctors can control the robot to have surgery.Robots can also serve our daily life.Most of us may already know that the robot cooks in the university cafeteria of Beijing Jiaotong University.We all think that it’s very interesting.These pictures show us the process of the robot cooking.First, the chef puts raw materials into the robot, then choses the dish to cook in the display screen.Next, the robot starts to cook.In the cooking process, the chef follows the robot’s voice prompts to add spices.Just three minutes later, the robot pours the cooked dish into the prepared basin.The robot cooking not only takes less time but also uses less gas.It can save fifty percent of gas.As the above examples allude, teleoperator robots provide service for mankind and make our life more convenient.Meanwhile they save us a lot of time and sources of energy.I believe in the future teleoperator robots will be more widely used and provide better service to our life.That’s all.Thank you.

Abstract: Graphite-filled poly-vinyl alcohol(CG-PVA)membranes were prepared by the solution blending method and characterized with FTIR, SEM and XRD methods.The results showed that graphite was uniformly distributed in the membrane matrix, there was stronger interaction between PVA and graphite particle, the crystallinity of the membranes decreased after the incorporation of graphite.The swelling and sorption properties of CG-PVA membranes in benzene/cyclohexane mixtures were investigated.The free volume properties of CG-PVA membrane were analyzed by positron annihilation lifetime spectroscopy, and apparent fractional free volume was calculated, which showed the same tendency of charge as permeation flux.Finally, the effect of graphite content and particle size on pervaporation properties were investigated.The pervaporation results indicated that the CG-PVA membranes exhibited good separation properties for benzene/cyclohexane mixtures, and the benzene flux and separation factor could reach 90.7 g·m-2·h-1 and 100.1, respectively, for benzene/cyclohexane [50/50,%(mass)] mixtures.摘要:采用液相共混法制備了石墨填充聚乙烯醇膜,采用FTIR, SEM, XRD等對石墨填充聚乙烯醇膜的物理和化學結(jié)構(gòu)進行了分析表征,結(jié)果表明石墨與聚乙烯醇存在較強的氫鍵作用,石墨在聚乙烯醇中分散均勻,且具有一定的取向性.考察了石墨填充聚乙烯醇膜在苯和環(huán)己烷溶液中的溶脹和吸附行為.采用正電子湮沒壽命譜儀表征了石墨聚乙烯醇膜的自由體積特性,計算得到石墨聚乙烯醇膜的表觀自由體積分數(shù),并且與滲透通量進行關(guān)聯(lián)性對比.最后,研究了石墨含量和粒徑對滲透蒸發(fā)分離性能的影響,結(jié)果表明,石墨的引入有利于苯的優(yōu)先透過,石墨填充聚乙烯醇膜對苯和環(huán)己烷混合物具有良好的分離效果,苯的滲透通量和分離因子分別可達90.7 g·m-2·h-1和100.1.
