In the field of microbiology, the development of molecular biology, moleculargenetics and ecology has promoted the development of environmental microbiology.Many microbial application technologies have penetrated into the environmentalprotection work, and played an important role in improving human living environmentand eliminating environmental pollution. Microorganism is the basic component of natural ecosystem, which is closely connected with material circulation and energy flow. It decomposes all kinds of organic matters in the environment, including all kinds of wastes and organic pollutants generated by human activities, maintains the relative balance of natural ecosystem while maintaining its growth and reproduction, and helps human beings“clean” the environment.

Environmental microbiology is a professional basic course for environmentalprotection majors. It provides students with the necessary basic theories and experimentalskills of microorganisms for learning water pollution control engineering, air pollutioncontrol engineering, environmental monitoring, solid waste treatment and utilization andother professional courses. Higher vocational colleges train high skilled applied talents tomeet the needs of production, service and management. For this purpose, the compilationof this textbook systematically introduces the basic knowledge of microbial morphology,structure, nutrition, metabolism, growth and reproduction, and genetic variation in accordance with the principles of “theoretical teaching sufficiency” and “practice,practicality and practice”. On the basis of meeting the needs of subsequent courses, some contents are adjusted and deleted. For example, the metabolism of microorganisms is only introduced the metabolism of production capacity. In the practical application of microorganisms, the influence of microorganisms on the environment, the role of
microorganisms in the natural material circulation, and the application of microbial technology in environmental management are introduced. The experimental part includes the basic skills and operation methods of microorganisms, the detection of microorganisms in water and air, the separation, screening and cultivation of high efficient pollutant degradation strains.

Due to the limited level of editors, it is difficult to avoid the mistakes or omissions in the book. We sincerely ask our colleagues and readers to criticize and correct them.

     With the acceleration of the global warming process and the shortening of the global abnormal climate occurrence cycle, sustainable development has attracted the attention of the whole world in today's population expansion, the destruction of the earth's environment, the depletion of resources and other issues. People began to reflect on the increasing development of construction projects. In the one hundred years since the
      Industrial Revolution, the construction industry has a great impact on the environment. The construction industry is a “big energy consumer”. 50% of the global energy consumption lies in the building, and the energy consumption of HVAC accounts for 30%~50% of the building energy consumption, and increases year by year with the improvement of people's requirements for the quality of life. In the process of sustainable design, under the influence of various financial crises and energy crises, people reduce the energy consumption of buildings by reducing the fresh air volume, reducing the operation power of air conditioner, reducing the air volume of circulating fans and other measures.
However, while reducing energy consumption, it also reduces people's comfort level to the lowest limit. Energy consumption has decreased, but new problems have arisen and air quality is deteriorating. With the development of the construction industry, people's awareness level is constantly improving. HVAC professionals gradually understand that energy conservation and environmental protection should be organically unified. Therefore, with the minimum energy consumption, creating a healthy and comfortable indoor environment and protecting the atmospheric environment is exactly the requirements of the new building for HVAC specialty.
       HVAC equipment is a huge and complex system engineering. As professional HVAC technicians, we must strictly grasp each process to ensure the normal use of the building's HVAC system.
        The main content of this book includes: HVAC system, HVAC cold and heat sources, HVAC energy saving technology, HVAC system and equipment control energy saving, HVAC system automatic control and noise isolation, HVAC construction and installation basic knowledge, central heating equipment construction and installation process, HVAC engineering construction and installation process, refrigeration pipeline and equipment construction and installation worker, operation and commissioning of ventilation air conditioner and refrigeration system and anti corrosion and heat preservation of HVAC system.

Infectious diseases are a kind of diseases caused by various pathogens, which can spread between people, animals or between people and animals. At present, China’s legally reported infectious diseases are divided into three categories: A, B and C, totally 39 species. In addition, it also includes other infectious diseases that National Health Commission of People’s Republic of China has decided to list in the management of B and C infectious diseases and other infectious diseases that carry out emergency monitoring reports in accordance with A management.
     Infectious disease is a disease that can be transmitted from one person or other species to another through various ways. Usually, the disease can be transmitted through air, water, food, contact, soil and vertical transmission (mother to child transmission), etc. It can be transmitted through direct contact with infected individuals, body fluids and excreta of infected persons, and objects contaminated by infected persons.
     Infectious diseases are characterized by ferocity, great harm, wide spread and great social impact. Since the beginning of history, human beings have been fighting against various infectious diseases. With the improvement of transportation level and the increase of floating population, the prevention of infectious diseases is no longer a simple prevention in a region or a country, but has been expanded to the world. The prevalence of SARS is still fresh in people’s memory.
     In this book, the basic knowledge of infectious diseases and related research applications are introduced in detail, and a large number of the latest examples and data are used to explain, so as to make contributions to the cause of health education and prevention and control of infectious diseases in China as far as possible, and provide reference for the majority of infectious disease researchers, which is also the original intention of this book.

传染病(Infectious Diseases) 是由各种病原体引起的能在人与人、动物与动物或人与动物之间相互传播的一类疾病。中国目前的法定报告传染病分为甲、乙、丙 3类.共 39 种。此外，还包括国家卫生计生委决定列入乙类、丙类传染病管理的其他传染病和按照甲类管理开展应急监测报告的其他传染病。
       传染病是一种可以从一个人或其他物种，经过各种途径传染给另一个人或物种的感染病。通常这种疾病可借由直接接触已感染之个体、感染者之体液及排泄物、感染者所污染到的物体，可以通过空气传播、水源传播、食物传播、接触传播、土壤传播、垂直传播(母婴传播)等。
      传染性疾病的特点是来势凶猛危害性大，传播范围广，社会影响大。而从有历史记载以来，人类一直就在与各种传染性疾病作斗争。随着交通运输水平的提高，流动人口的增加，传染病的预防已不再是简单的某个地区或某个国家进行预防，现已扩大至全球。 SARS 的流行至今人们还记忆犹新。
      本书中详细介绍了传染病的基础知识和相关的研究应用，大量采用最新实例与数据说明，以期尽可能为我国传染病健康教育与防控事业做出贡献，为广大传染病研究工作者提供参考，这也是我们编写这本书的初衷。
