我们根据多年使用、检修、校正光干涉型甲烷测定器的经验,结合新疆的具体情况对大气压影响干涉条纹间距的问题,提出我们的一些看法。测定器是否准确好用,主要取决于下面三个条件:(1)气密性良好、包括瓦斯进出口的连接胶管、辅助管、吸气球以及空气室、瓦斯
We put forward some of our opinions based on the experience of using, overhauling, and correcting the light interference methane measuring device for many years and combining the atmospheric conditions affecting the spacing of interference fringes according to the specific conditions in Xinjiang. The accuracy of measurement is easy to use, mainly depends on the following three conditions: (1) air tightness, including the import and export of gas connection hose, auxiliary tube, suction balloon and air chamber, gas
