With the continuous improvement of science and technology and the wide application of new technology and people’s deep understanding of obstetrics and gynecology diseases, the prevention and treatment of women’s health and obstetrics and gynecology diseases has attracted extensive attention of the society. It is a necessary quality for every gynecologist to know about how to correctly understand obstetrics and gynecology diseases, how to timely and accurately diagnose obstetrics and gynecology diseases, how to treat obstetrics and gynecology diseases scientifically and reasonably.
      With the rapid development of science and technology, the basic knowledge and clinical diagnosis and treatment of obstetrics and gynecology have made great progress, the etiology and pathogenesis have been deeply studied, and the diagnosis and treatment of diseases have also been widely practiced. With the change of medical model and the renewal of traditional medical concept, many diagnosis and treatment methods and principles of Obstetrics and Gynecology have changed with each passing day. Considering this, the writer has compiled the book on the basis of referring to a large number of literature and combining with their own clinical work experience for many years.
      The book has systematically expounded the etiology, clinical manifestations, diagnosis and treatment of obstetrics and gynecology diseases, reflected the new ideas and knowledge of modern clinical practice, and has strong practicability and guidance; with rigorous structure, distinct levels, novel content, high professional degree and strong practicability, it can not only reflect modern clinical experience, but also meet the needs of other clinical workers. Therefore, it can be used as a reference book for staffs at all levels.

Geotechnical Engineering, literally translated as “geological technology engineering”, which is a new technical system established by European and American countries on the basis of civil engineering practice in the 1960s. It is a subject that mainly studies engineering issues of rock mass and soil mass. This book mainly introduces geotechnical engineering and geological exploration technology.
         Engineering exploration technology is an important means of construction engineering exploration, which directly serves foundation and the design of foundation engineering. The use of reasonable exploration methods is the key to ensuring the safety and stability of construction projects and the rationality of technology and economy. The editors and their teaching team summarized years of experience in teaching, scientific research, and practice, based on the principle of equal emphasis on practical technology and theoretical foundation, coordinated the relationship between basic theory and modern technology, and absorbed advanced production equipment and production technology. The editors coordinate the content of each chapter to make it closer to production practice.
      Geotechnical engineering is an interdisciplinary subject, which is widely used in highways, railways, bridges, tunnels, dams, airports, industrial and civil buildings and other fields. On the basis of prerequisite courses such as soil mechanics, foundation engineering and engineering geology, students have a comprehensive, systematic and in-depth understanding of the basic knowledge, theories and methods of geotechnical engineering through the study of this course, so that they can solve the practical problems of geotechnical engineering. On this basis, they can engage in exploration, design and construction of geotechnical engineering, and have certain research and development capabilities.

前 言

岩土工程（Geotechnical Engineering），直译为“地质技术工程”，是欧美国家于 20 世纪 60 年代在前入土木工程实践的基础上建立起来的一个新的技术体系，它主要是研究岩体和土体工程问题的一门学科。本书主要介绍了岩土工程与地质勘查技术。
        工程勘察技术是建设工程勘察的重要手段，直接服务于地基和基础工程设计。采用合理的勘察技术手段是确保建设工程安全稳定、技术经济合理的关键。本书结合了编者及其教学团队的多年教学、科研、实践的经验，以实用技术及理论基础并重为原则， 协调好基础理论与现代科技间的关系， 吸收先进的生产设备和生产工艺，统筹安排各章内容，使教材内容更能贴近生产实践。
        岩土工程是多门学科交叉的边缘学科，在公路、铁路、桥梁、隧道、堤坝、机场、工业与民用建筑等领域广泛应用。在土力学、基础工程和工程地质等先修课程基础上，学生通过本课程的学习，对岩土工程的基本知识、理论和方法有全面、系统和深入地了解， 使之具有解决岩土工程实际问题的能力， 能从事岩土工程的勘察、设计和施工，并具有一定的研究和开发能力。

随着现代社会的高速发展，企业对资产配置的需求越来越多，于是企业资产管理的说法不断被提出来，毕竟企业资产管理对于企业来说有着非常重要的意义，往往成熟的企业会采用资产管理系统来进行管理。从资产管理系统的历史来看，其发展得益于 ERP（企业资源计划）管理思想的诞生，由美国 Gartner Group 公司提出，后续 ERP 慢慢演变成网络经济时代的新型信息系统， 主要用于改善业务流程提高企业核心竞争力，之前的资产管理系统便是在此基础上进行开发。尽管资产管理系统发展到现在已经比较完善， 但由于我国的资产管理起步较晚， 而且还尚在推广阶段，并未大规模普及，我国的企业信息化建设仍然有很长一段路要走。
      会计是以货币为主要计量单位，采用一系列专门方法，对企事业单位实际发生的交易或者事项进行连续、系统、全面、综合的核算与监督，以提供真实、有用的会计信息，并在此基础上对经济活动加以预测、控制和决策。它既是一个经济信息系统，也是一项管理活动。
      在现代经济活动中，财务与会计是其重要的组成部分，在经济管理上具有重要的地位和影响。而在企业的经济管理活动中会计是直接工作人员，因此对经济管理进行优化，对会计工作也会有所提高。新经济是区别于传统经济概念的经济周期，随着现代社会的不断发展，对经济周期现象能够有效避免。从本质含义来看，新经济代表的是全球化和科技网络化，在这样的前提之下，财务会计自然会受到一定的冲击。企业的财务会计要结合实际发展情况，加强理论与实践研究，强化财务会计业务，使企业财务管理发生创新性的转变。

2016 年 2 月 6 日《中共中央国务院关于进一步加强城市规划建设管理工作的若干意见》中提出， 10 年内，我国新建建筑中，装配式建筑比例将达到 30%。由此，我国每年将建造几亿平方米装配式建筑，这个规模和发展速度在世界建筑产业化进程中也是前所未有的，我国建筑界面临巨大的转型和产业升级压力。发达国家装配式建筑技术是经历了半个多世纪发展起来的，是技术理论、技术实践和管理经验逐步积累的过程。但目前大多数国家装配式建筑比例也不到 30%。我们要用 10 年时间走完其他国家半个多世纪的路，需要学的知识和需要做的工作非常多，专业技术人员、技术工人和懂行的管理者的需求将非常巨大。
       近年来，现代化的预制部件部品生产企业的逐年增多，工程咨询、规划、设计、部品生产、施工、运营管理深度融合水到渠成。装配式建筑的组织管理模式不同于传统现浇建筑，正在逐步地由单一的专业性组织管理，向综合的全过程组织管理模式发展，装配式建筑强调工程系统集成与工程组织管理整体优化，显现了全过程组织管理的优势。当前，国内各地政府均相继出台了有关装配式建筑的文件规定，相应的地方标准规范不尽相同，工程项目的组织管理模式差异明显，迫切需要系统的梳理和研究。
