gas density meaning in Chinese

气体密度
瓦斯浓度

Infrared gas density meters
红外线气体浓度感测器
The sensor is linear output along with the change of gas density
传感器随气体浓度的变化呈线性输出，报警设定值可调。
This paper probes into some measures for the safety in production from three aspects of doing well the ceiling management of the mining face with complex geological structure , controlling strictly the gas density and spark origin in the mining face , and strengthening the safety training
从做好地质构造复杂工作面的顶板管理、严格控制井下工作面瓦斯浓度和引爆火源、加强安全培训工作3个方面探讨了安全生产的措施。
( 2 ) according to lambert - beer law and related optical signal processing technology , analysis formula is presented to express the relationship between spectrum intensity and gas density after the two widely used semiconductor light resource led and dfbld functioned with inferred absorption spectrum line
( 2 )依据朗伯比尔（ lambert - beer ）定律和光学信息处理技术，给出了两种常用半导体光源led和dfbld与红外吸收线作用后，光谱分量强度与气体浓度关系的解析表达式。
