However, China's rapid economic development has brought a series of hidden dangers to China's ecological environment development, which will seriously restrict China's sustainable development. Especially in some large cities, their garbage pollution, air pollution and water environment pollution are unprecedented serious, which has aroused people's extensive attention and general thinking on environmental problems. In order to make China's economic development get a virtuous circle and promote China's stable and green sustainable economic development, relevant government personnel are required to do a good job in environmental pollution supervision and formulate relevant environmental protection policies to fundamentally ensure the operation of China's environmental pollution treatment.展开更多

Most people in our society are now paying attention to how to realize the sustainable development of our society and economy, which is a problem that needs to be solved in our social development. Environmental testing is an indispensable core part of environmental protection work, and cannot be replaced. Advanced technology is used to measure the content standard of environmental pollutants, and comprehensive assessment is made on the environmental quality level and environmental pollution degree according to China's environmental protection parameters, laying a good foundation for the follow-up work of environmental protection.展开更多

Therefore, we must strengthen the environmental protection and maintain the ecological environment in an all-round way. In the process of carrying out environmental protection work, the most indispensable and important component is environmental testing, which plays a multifaceted role. It not only plays an important role in environmental protection, but also plays an important and positive role in economic environment and people's health. With the deterioration of environmental problems, the role of environmental testing is more prominent. Environmental testing is a new research science with obvious comprehensive advantages and rich scientific contents. This is a very important driving force in the process of urban economic development. Relevant departments should pay more attention to environmental testing. From the actual point of view, appropriate and effective environmental protection measures should be taken to protect the ecological environment and promote the harmonious coexistence of man and nature.展开更多

At present, China's environmental protection cause has attracted more and more attention from all walks of life. Environmental testing technology refers to the process of comprehensive evaluation of environmental quality, which should make full use of physical and chemical technology and biological technology to timely and comprehensively determine the pollutants in the environment. The non-compliance of resource allocation with the standards will lead to the imperfection of environmental testing data. At present, the hardware equipment of environmental monitoring technology in our country is relatively backward and cannot provide more accurate and reliable testing data.展开更多

Therefore, in order to further promote the harmonious development of man and nature, it is necessary to properly complete the environmental inspection work and effectively improve the environmental monitoring technology. At the same time, it is necessary to perfect and formulate relevant testing systems so that the environmental governance work can be relied on. The Environmental Protection Law stipulates that the subjective department of environmental protection administration under the State Council must establish an effective and perfect monitoring system, set scientific testing standards, and jointly establish an environmental testing network to improve the effectiveness of environmental management.展开更多

In order to realize the sustainable development of the environment, it is necessary to increase the research of environmental monitoring technology. If the environment is polluted, it will bring a series of chain reactions. If the specific pollution problem cannot be effectively controlled in a timely manner, it will seriously damage the entire ecosystem. At the same time, it will be irreversible. The environment on which people depend for their survival will also be adversely affected. If it continues to develop for a long time, it will be very disadvantageous to the development of the national economy as a whole. Based on this, this article focuses on the in-depth research and analysis of environmental testing technology and ecological sustainable development.展开更多

In recent years, while China has put forward the sustainable development, the development must be accompanied by environmental protection and ecological balance. Therefore, special attention must be paid to its role in the environmental management process. On this basis, the application of environmental monitoring and its contribution to environmental management are briefly introduced.展开更多

People have neglected the protection of the ecological environment due to their excessive pursuit of the quality of living standards, resulting in serious damage to air pollution and posing a great threat to people's lives and health. If we want to solve the problems caused by air pollution, we must start with the main sources of air pollution, formulate reasonable countermeasures and plans, not to delay people's normal industrial production and development, but also to effectively control the impact and threat of air pollution on people's lives, to provide protection for the environment on which human beings depend for survival, and to realize the sustainable development of industrial and atmospheric ecological environment.展开更多

In this paper, we propose a practical methodology and implement an environment by employing model-based robustness testing for embedded software systems. It is a system-level black-box testing approach in which the fault behaviors of embedded software is triggered with the aid of modelbased fault injection by the support of an executable model-driven hardware-in-loop （HIL） testing environment. The prototype implementation of the robustness testing environment based on the proposed approach is experimentally discussed and illustrated by industrial case studies based on several avionics-embedded software systems. The results show that our proposed and implemented robustness testing method and environment are effective to find more bugs, and reduce burdens of testing engineers to enhance efficiency of testing tasks, especially for testing complex embedded systems.展开更多
