The construction industry is the basic industry for national economic and social development. It is one of the important indicators to measure the level of industrialization in a country and region. With the continuous progress and development of the society, the market economy continues to deepen. The market competition in the construction industry is becoming increasingly fierce, and the scale of construction projects is expanding. Construction engineering management has received more and more attention. Quality is the life of engineering construction in building construction, and management is the lifeblood of engineering quality. The improvement of engineering construction management has become crucial for the development and construction of the project. The construction management process is actually the process of information flow. Management and control are achieved through the vertical flow of information from the upper to the lower or from the lower to the upper, and the lateral flow at the same level. The project is a market-oriented window for construction companies, and project management is the foundation of enterprise management. With the vigorous development of China's economy, market competition has become increasingly fierce. This requires us to continuously deepen and refine the management of the project construction on the basis of the past to achieve greater social and economic benefits. Construction management includes construction site management, project cost management, project schedule management, project quality management, construction safety production management, and other management content.

In order to pursue a space for better development and survival, construction companies must continually enhance their ability to manage projects and determine scientific, rational costs, schedules, safety, and quality related goals. Measures such as economy, technology, organization, and contract are comprehensively applied to control the three major objectives, thereby achieving good social and economic benefits. Today's construction industry has become one of the industries with low profits due to many factors such as low overall management level of enterprises, unsound responsibility cost management system, obsolete management methods and means. This has endangered the survival and development of construction and construction products quality and safety. How to control the cost of construction projects, strengthen the cost management of the whole construction process, improve the economic benefits of construction enterprises and realize the sustainable development of construction enterprises has become the primary task of the construction industry. Construction site management is the core of project management and the key to ensure the quality and safety of construction projects. Scientific management of construction site is the fundamental way to set up corporate image, improve corporate reputation, and obtain economic and social benefits. The management of project schedule is an essential and important link in project management. It has a very special and important role and status. The quality management of construction engineering is a systematic engineering. Only by doing the work of each link carefully and responsibly can the quality management of construction project be done well. In the construction process of a building project, safety is one of the first factors to be considered. Without safety, it is impossible to produce benefits in building construction. There is no contradiction between ensuring the safety of construction projects and ensuring the production schedule. On the contrary, if the relationship between the two is properly handled, it can greatly promote the smooth implementation of construction projects. Of course, there are other management content, which will not be repeated here.

Our intention in writing "Building Construction Management" is to provide a practical textbook and reference book for the majority of construction industry practitioners. However, because this book covers a wide range of content, involves more complex knowledge, and has a large number of writers, the format, depth and breadth of each chapter may not be consistent, and fallacies are inevitable. Readers are invited to criticize and correct.

建筑业是国民经济和社会发展的基础产业，是衡量一个国家和地区工业化水平的重要标志之一。随着社会的不断进步和发展，市场经济的不断深化，建筑业的市场竞争日趋激烈，建设项目规模不断扩大，建筑工程管理越来越受到人们的重视。在建筑施工中质量是工程建筑的生命，管理就是工程质量的命脉，提高工程施工管理对于项目的开发与建设变得至关重要。建筑施工管理过程其实就是信息流动的过程，通过信息从上层到下层或从下层到上层的纵向流动，以及在同一层次问的横向流动，达到管理和控制的目的。工程项目是建筑施工企业面向市场的窗口，工程项目管理是企业管理的基础，随着我国经济的蓬勃发展，市场竞争也日趋激烈，这就要求我们就项目施工的管理在以往的基础上，要不断深化、细化以取得更大的社会效益和经济效益。建筑施工管理包括施工现场管理、工程成本管理、工程进度管理、工程质量管理、施工安全生产管理以及其他管理内容。

为了追求更好地发展和生存的空间，建筑企业必须不断地增强对项目的管理能力，并确定科学、合理的成本、工期、安全以及质量的相关目标。综合应用经济、技术、组织以及合同等措施实行对三大目标有效地控制，进而取得好的社会效益以及经济效益。当今的建筑施工行业，由于受企业整体管理水平偏低、责任成本管理制度不健全、管理方式和手段陈旧等诸多因素的制约，已成为低利润的行业之一，已经危及建筑施工的生存和发展以及建筑施工产品的质量和安全。如何控制建筑工程施工项目的成本，加强工程施工全过程成本管理，对提高施工企业的经济效益，实现施工企业的可持续发展，成为现今建筑业的首要任务而施工现场管理是工程项目管理的核心，也是确保建筑工程质量和安全文明施工的关键。对施工现场实施科学的管理，是树立企业形象提高企业声誉，获取经济效益和社会效益的根本途径。工程进度的管理在项目的管理当中，是必不可少的一个重要环节；其有着非常特殊地重要的作用和地位。建筑工程的质量管理是一个系统工程，只有认真负责地做好各个环节的工作，才能真正搞好建筑工程的质量管理。建筑项目施工过程中，安全因素是首先要考虑的因素之一。没有安全保障，建筑施工目是不可能产生效益的。保障建筑施工项目的安全与保证其生产进度并不矛盾，相反，处理好二者的关系，能够在很大程度上促进建筑施工项目的顺利实施。当然，还有其他管理内容，这里就不再一一赘述。

我们编写《建筑施工管理》的意图是为广大建筑业从业者提供一本切合实用的教材与参考书。但因为本书包罗内容较广，涉及知识较烦琐，编写人员较多，各章节内容的格式、深度和广度可能并不一致，谬误无可避免，请读者批评指正。

With the continuous development of society, the chemical industry also has certain requirements on its mechanical equipment. The production conditions of chemical industrial products are mostly high temperature, high pressure, complex medium conditions and high technical content, and most of their raw materials and products are highly toxic, flammable, explosive and highly corrosive substances. Chemical production plays an important role in the development of the national economy. Therefore, the performance and reliability of the basic equipment for chemical industry production and operation are very high. Without reliable equipment, the chemical industry has no basis for survival. The reliability of equipment operation determines the normal production of chemical industry. The process of modern industrial production is increasingly moving toward the development direction of large-scale, refined and integrated. The overall operation of a chemical plant is actually an extremely complex and large system. Once one of the links fails and the appropriate solution is not taken in time, a major accident will occur in the entire system. Therefore, it is necessary to strictly control the design process of chemical machinery equipment to ensure the normal and safe operation of each link.

This book briefly describes the chemical equipment materials, centrifugal compressors, turboexpanders, valves, general manufacturing technology of process equipment, heat exchangers, tower equipment, cryogenic liquid storage and transportation equipment.

随着社会的不断发展，化工业对其机械设备也有了一定的要求。化工业产品生产条件多为高温、高压、复杂介质条件，高技术含量的，其原料及产品又大多为剧毒、易燃、易爆、强腐蚀性物质，因为化工生产在国民经济发展中占据着重要地位，所以，对于化工业生产运行的基础设备的性能、可靠性就非常高，离开了设备，或者说离开了可靠的设备，化工业就失去了生存的基础，设备运行的可靠与否就决定了化工业生产的正常与否。而现代化工业生产的过程日益趋向大型化、精细化和集成化的发展方向运行，一台运行着的化工设备，整体实际上是一个极其复杂的大系统。而一旦其中的某一个环节发生故障，或者哪一部分使用不当又没有及时采取合适的解决措施，就会导致整个系统发生重大事故，因此，必须要对化工机械设备设计过程进行严格的控制，确保每个环节的正常安全运行。

本书将通过对化工设备材料、离心式压缩机、透平膨胀机、阀门、过程设备通用制造技术、换热器、塔设备、低温液体储运设备等进行了简单的阐述。

As the main channel to implement Chinese curriculum, Chinese classroom teaching always changes with the change of the nature of Chinese curriculum. Throughout the history of the change of the nature of the Chinese curriculum, whether emphasizing the instrumental or ideological nature, the Chinese classroom teaching always presents the characteristics of unitarity, inculcation and “its emphasis on things and neglect of student”. The new curriculum not only brings a series of innovation of Chinese teaching ideas, but also brings opportunities for the development and utilization of Chinese classroom teaching resources.

The book consists of ten chapters. First, this book introduces the evolution of Chinese classroom teaching and the process of new curriculum reform and the current situation of Chinese classroom teaching design in technical schools under this background. Then, it expounds the foundation of Chinese teaching design, the design of Chinese teaching plan, teaching process, teaching method, classroom control and other teaching process concepts in the new curriculum reform, as well as the design of different teaching contents such as reading, composition, listening and speaking and extracurricular activities. This book adheres to the principle of combining theory with classroom practice to provide more practical guidance books for Chinese classroom teaching in various vocational and technical schools in China, and makes contributions to the vigorous development of China's educational career.

People are the source of national strength, food is the paramount necessity of people, and food safety is the top priority. Food is indispensable to people every day. Therefore, food safety must be one of the most concerned issues in the society. In recent years, domestic media have reported a large number of food safety incidents, including the melamine in Sanlu milk powder, Sudan in KFC food, iodine excess of nestle milk powder, Haagen-Dazs incident and so on, which have aroused high attention from all sectors of society. This has triggered doubts and reflections on China's food safety management mechanism. It involves the long-term supervision function of relevant functional departments, situation assessment and emergency response ability, media supervision and control, incident responsibility tracing, popularization of public food safety knowledge, and connection and communication with international food safety standards. These questions must be addressed in a positive, efficient, scientific and responsible manner within a short period of time. These events triggered our thinking on the establishment and improvement of China's food safety crisis management system. The purpose of this book is to explore how to improve the ability of food quality testing and management in China.
