With the development of industry, air pollution is serious and respiratory diseases are increasing day by day, so it is necessary for hospitals to set up respiratory department. Respiratory diseases are mainly divided into the following categories: pulmonary infection, pulmonary manifestations of systemic diseases, diffuse pulmonary diseases, chronic obstructive pulmonary diseases and asthma, pulmonary circulation diseases, disorders of ventilation regulation, rare pulmonary diseases, acute respiratory distress syndrome, mechanical ventilation and respiratory monitoring, lung cancer, etc.
This book first summarizes the basic theory and diagnosis of respiratory medicine and respiratory diseases, and then dialectically diagnoses and treats the above respiratory diseases. The contents of the book are comprehensive, rich and practical, which is instructive and can be used as a reference for medical staff, especially respiratory professionals.
As this book covers a lot of contents and involves a lot of knowledge, the format, depth and breadth of the contents of each chapter may not be the same, and fallacies are inevitable. Readers are welcome to criticize and correct it.

随着工业的发展，空气污染严重，呼吸道疾病日益增多，所以医院设立呼吸内科是非常有必要的，呼吸系统疾病主要分以下几种、肺部感染、全身疾病的肺部表现、弥漫性肺部疾病、慢性阻塞性肺疾病和哮喘、肺循环疾病、通气调节功能障碍性疾病、少见肺部疾病、急性呼吸窘迫综合征、机械通气和呼吸监护、肺癌等。
本书首先对呼吸内科以及呼吸系统疾病的基础理论与诊断进行概述，然后分别对以上呼吸系统疾病进行辩证诊断与论治。全书内容全面、丰富、实用，很有指导意义、可供广大医务人员，尤其呼吸专业人员参考。
由于本书包罗内容较多，涉及知识较烦琐，各章节内容的格式、深度和广度可能并不一致，且谬误无可避免，敬请广大读者批评指正。

Electric power industry is the basic guarantee for the sustainable growth of social economy, with the improvement of social productivity, the demand for electric energy in various industries increases accordingly, promoting the intelligent reform of power grid become the mainstream trend. In the new period, to promote the construction and reform of smart grid, a large number of advanced technologies and equipment need to be applied. Among them, relay protection is the guarantee of safe operation of power grid, promoting the improvement and perfection of relay protection technology and playing a positive role in the stable operation of smart grid.
     In the process of construction and development, smart grid greatly improves the operation efficiency and stability of power system, as the basic guarantee for stable operation of power grid, the relay protection technology has made considerable achievements in practical application. Nowadays, China’s smart grid construction process is accelerating, new requirements is proposed for relay protection technology in the new era. Promoting the improvement and perfection of relay protection technology can push forward the improvement of power grid informatization and automation level, as well as solve the problem of power shortage. By studying and analyzing the new relay protection technology of smart grid, it can improve the shortcomings and provide support for the subsequent development of smart grid.

Environmental ecology is an interdisciplinary subject between ecology and environmental science, and is one of the important applied subjects of ecology. Environmental ecology is a science that studies the internal change mechanism, law and counter effect of ecosystem on human under the human disturbance, and seeks for the recovery, the reconstruction and the protection countermeasures of the damaged ecosystem. That is to say, use the ecological theory to clarify the interaction between human and environment and find out the ecological way to solve environmental problems. Therefore, environmental ecology is different from the classical ecology, which mainly studies the relationship between living environment and living environment, and it’s also different from the pollution ecology, which only studies the behavior rules and hazards of pollutants in the ecosystem. Besides, it’s different from the social ecology, which studies the structure, function, evolution mechanism of social ecosystem, as well as the interaction between individuals and organizations of human beings and the surrounding natural and social environment. It is a subject to solve two kinds of environmental problems: environmental pollution and ecological damage.
With the rapid development of environmental protection, China’s ecological protection work has gradually been upgraded to an unprecedented level. The focus of environmental protection work has changed from simple pollution control to the strategic goal of paying attention to ecological protection and realizing ecological virtuous cycle. As an important means to understand and master the current situation and the trend of ecological environment quality, ecological environment monitoring has become an essential part of environmental monitoring. However, due to the complexity, diversity and huge regional differences of the ecosystem, it is necessary to establish a set of systematic technical specifications and methods to reflect the ecological environment scientifically, comprehensively and objectively.

环境生态学是生态学和环境科学之间的交叉学科，是生态学的重要应用学科之一。环境生态学是研究在人为干扰下，生态系统内在的变化机理、规律和对人类的反效应，寻求受损生态系统恢复、重建和保护对策的科学，即运用生态学理论，阐明人与环境间的相互作用及解决环境问题的生态途径。因此，环境生态学不同于以研究生物与其生存环境之间相互关系为主的经典生态学，也不同于只研究污染物在生态系统中的行为规律和危害的污染生态学和研究社会生态系统结构、功能、演化机制以及人的个体和组织与周围自然、社会环境相互作用的社会生态学，它是解决环境污染和生态破坏这两类环境问题的学科。
随着环境保护事业的快速发展，我国的生态保护工作已逐渐被提升到前所未有的高度，环境保护工作的重点已由单纯污染控制转向以注重生态保护和实现生态良性循环为战略目标。作为了解和掌握生态环境质量现状及其变化趋势的重要手段，生态环境监测成为环境监测必不可少的重要组成部分。然而，由于生态系统的复杂性、多样性以及巨大的地域差异性，要科学、全面、客观地反映生态环境状况就需要建立起一套系统的技术规范和方法。
