在地球环境保护方面,关于燃烧排气限制的问题作为政令正在具体化,其涉及的范围大到火力发电厂,小到家庭燃烧器。还有汽车的各种内燃机春相类似的机种等都应作出相应的改善。在各种技术改善的措施上采用部分气体传感器的开发是非常重要。使用这些传感器必须考虑以下两个方面:(1)能够充分地改善周围环境。(2)费用上要适合于相应的机种。虽然考虑这些方面进行开发的历史比较 In the protection of the Earth’s environment, the issue of burning exhaust restrictions is being codified as a decree that covers a large area ranging from thermal power plants to household burners. There are also a variety of internal combustion engine models similar to the spring should be made to improve accordingly. It is very important to adopt some gas sensors in various technical improvement measures. The use of these sensors must consider the following two aspects: (1) can fully improve the surrounding environment. (2) The cost should be suitable for the corresponding models. Although considering these aspects of the history of the development of comparison
