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.

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.
