求翻译：煤气作为一种高能能源，在存储、运输、使用过程中都存在不同程度的危险，有可能对人民群众的人身安全和财产安全造成相当大的危害。因此，对管道煤气压力控制系统的研究具有十分重要的意义。管道煤气压力控制系统就是利用管道中的压力作为被控制量，保证输出一个恒定气压的负反馈控制系统。是什么意思？

Gas as an energy-energy in the storage, transport, use, there are varying degrees of risk, it is possible to cause considerable harm on the people's personal safety and property security. Therefore, the study of the pipeline gas pressure control system is of great significance. Pipeline gas pressure

Gas as a high-energy, energy storage, transport, use process is present in varying degrees of risk, it is possible that the masses of the personal safety and property security resulted in considerable danger. Therefore, the piping gas pressure control system with 10 of the study is of great signific

The coal gas took one kind of high energy energy, in the memory, the transportation, the use process all has the varying degree the danger, has the possibility safely causes the quite big harm to people's personal safety and the property.Therefore, has the extremely vital significance to the pipelin

Gas as an energy-energy, storage, transportation, use, there are different levels of risk in the process, it is possible to personal safety and property of the masses caused considerable damage. Therefore, on the pipeline of gas pressure control system is of great significance in the research. Pipel
