Karst areas are distributed in Southwest China, accounting for nearly 1 / 3 of the total area of Southwest China. The landform of karst area is complex, and the development of karst has the characteristics of uncertainty and concealment. Therefore, it is very difficult to carry out the geological survey of engineering construction in karst area. Karst may induce the corresponding geological disasters, which brings not only the construction difficulties on the terrain, but also need to be taken seriously in the specific engineering construction.

  Karst is the general name of some phenomena produced by the geological process, which is dominated by chemical dissolution and supplemented by water mechanical action, such as erosion and undercutting. The landform formed by karst is called karst landform. At present, many researchers have carried out various researches on it, and have made good achievements in some fields. However, as our country builds more and more projects in karst areas, there are more and more problems encountered in engineering surveys. Although engineers and technicians have constantly summed up a lot of experience in the process of surveying, the geology and landforms of karst areas are complex and diverse, and the geological survey technology needs further research.

  It is very necessary to conduct effective surveys of engineering construction geology in karst areas. The development of karst in karst areas is a very troublesome problem, and its uncertainty and concealment add to the difficulty of technical surveys. Its uncertainty and concealment make technical surveys more difficult. Therefore, under realistic geological and geomorphic conditions, when we carry out engineering construction in karst areas, we must combine the corresponding geological survey technology according to the specific work conditions. Only by understanding the relevant changes in the karst area in detail can we make a reasonable engineering construction plan. However, in the specific survey process, there are still many problems that will arise. These problems may have never been encountered before and cannot be solved with existing technology. In the face of this situation, we have to constantly strengthen the updating of technology and find out new technical methods, in order to better complete the engineering construction under the karst geological conditions.

岩溶地区要分布在我国的西南地区，面积将近占了西南地区总面积的 1/3。岩溶地区的地形地貌比较复杂，岩溶的发育具有不确定性和隐蔽性的特征，因而在进行岩溶地区工程建设地质勘察的过程中，难度相当大。岩溶可能诱发相应的地质灾害，这就给工程建设带来了不仅仅是地形上的建设困难，还需要在具体的工程建设中认真的对待。
       岩溶是指水对可溶性岩石作用时，以化学溶蚀为主，水的机械作用冲蚀、潜蚀等为辅的地质作用所产生的一些现象的总称，也可叫做喀斯特。因为喀斯特作用形成的地貌，叫做喀斯特地貌。目前许多的研究者已经对其展开了多方面的研究，并组在一些领域取得了比较好的成就。但是，随着我国在岩溶地区建设的工程越来越多，在进行工程勘察时遇到的问题也就越来越多。虽然工程技术人员在勘察的过程中，也不断的总结了许多经验，但是岩溶地区的地质地貌繁杂多样，地质勘察技术还有待进一步的研究。
      对岩溶地区工程建设地质进行有效的勘察是非常有必要的。岩溶地区的喀斯特发育状况是一个非常麻烦的问题， 它的不确定性及隐蔽性加重了技术勘察上的难度。因此，在进行岩溶地区工程建设时，我们必须针对具体的工作情况，在现实的地质地貌条件下，结合相应的地质勘察技术，详细的了解和地岩溶的相关变化情况，从而做出合理的工程建设方案。但是，在具体的勘察过程中，还有很多问题会出现，这些问题有可能是以前我们从来都没有遇见的，用现有的技术也无法加以解决的。面对这种情况时，只有不断地加强技术方面的更新以及寻找出新的技术方法，我们才能够更好的完成岩溶地质条件下的工程建设。

“Archives” is no longer a mysterious thing in modern civilized society. In their work, life and study, people feel more and more clearly that archives are around and everyone has to deal with them. We should not only understand the concept of archives, but also further understand how archives are used in all walks of life. Only in this way can we have a deeper understanding of archives, cherish archives more consciously and make active use of archives.
  As a hospital archives, its value and function are mainly reflected in the following parts: first, as a reference certificate for the work of hospital organs. In order to carry out the work effectively, the party and government organs in hospitals must comprehensively grasp the situation. Archives are the historical records of the activities of the hospital organs. They can provide the basis and consulting materials for the organs to carry out the work and make decisions. The use of hospital archives is conducive to the scientific planning and decision-making, overcoming bureaucracy and blindness, and improving the work efficiency of the leading cadres in hospitals; secondly, the reference basis of hospital operation and management, which records the achievements, experiences and lessons of predecessors in various types of work, can provide scientific basis and reference materials for the future operation and management of the hospital, especially medical records, technology and other files, which are indispensable important materials for hospital management; finally, reliable data and archives of medical research can provide a large number of scientific research records, experimental materials, observation materials and theoretical summary materials for medical scientific research, and create necessary conditions for future medical research.

  To this end, we wrote this book, the purpose is to make an in-depth analysis of the ways of hospital file management, and actively look for a more reasonable way of file management. We hope this book can achieve the effect of using the little to get the big.

档案”在现代文明社会已经不是什么神秘的东西了,人们在自己的工作、 生活、学习中，越来越清楚地感受到档案就在身边，人人都要和它打交道。对档案的认识不仅要从概念上理解， 我们还要进一步了解档案是如何运用到各行各业的,这样才会对档案有一个较深刻的认识，才能更自觉地珍爱档案，积极地利用档案。
       作为医院档案馆的价值和作用主要体现为以下几个部分：首先，作为医院机关工作的查考凭证。医院党政机关为有效地开展工作，必须全面地掌握情况，档案是医院机关活动的历史记录， 它可以为机关开展工作， 进行决策提供依据和咨询材料，利用医院档案， 有助于计划和决策的科学化,有利于克服官僚主义和盲目性,提高医院领导干部的工作效率；其次，医院运营和管理的参考依据，档案记载前人在各项工种中的情况成果、经验与教训，它可为医院今后的运营和管理提供科学依据和参考材料,尤其是病历、技术等档案，更是医院管理不可或缺的重要材料；最后，医疗研究的可靠资料,档案可以为医学科学研究提供大量的科研记录、实验材料、观察材料及理论概括材料,为日后的医学科研创造必要的条件。
        为此，我们撰写了《新时代背景下的医院档案管理与创新研究》一书，目的是对医院档案管理的方式进行深入分析，并积极寻找更加合理的档案管理方式。希望本书能够达到抛砖引玉的效果。

As an important means of transportation, cars bring convenience and comfort to people’s life, but also bring many negative effects. With the increasing number of cars in the world, energy consumption, environmental pollution and greenhouse effect have become global problems. It is urgent to seek alternative energy and develop green transportation. New energy vehicles use unconventional alternative fuels other than gasoline and diesel or electric energy and solar energy as power sources, which have the advantages of less pollution, lower noise, higher conversion efficiency and lower cost. It is regarded as the most effective way to save energy and reduce emissions and reduce dependence on oil in the automotive industry.
  Although the research and development of new energy vehicles in China started late, it has developed very fast under the strong support of national policies. At present, China’s automobile industry takes pure electric drive as the main strategic direction of technology transformation, focusing on breaking through battery, motor and electronic control technology, and promoting the industrialization development of pure electric vehicles. Domestic vehicle manufacturers, such as FAW, Dongfeng, SAIC, Zitong, BYD, Zhongtai, Qingnian, Geely and Chery, have also launched their own R & D and design of hybrid electric vehicles and pure electric vehicles. The rapid development of China’s pure electric vehicles and their key components, such as power batteries and drive motors, has given China’s pure electric vehicles the opportunity to compete with western developed countries on the same level in the field of new energy vehicle technology.
