求翻译：Based upon this data, as well as measured gas temperature and sonic velocity, the gas or vapour concentration is determined. The accuracy of measurement is dependent on the difference between to molecular weight of the two component gases, and the larger the difference, the more accurately the instrument will measure c是什么意思？ 待解决

基于这一数据，以及被测气体的温度和声速，气体或蒸气的浓度决定。测量精度依赖的两个组成部分气体，分子量和较大的差异之间的差异，更准确地将测量仪器的浓度，例如它是可以测量氢三甲基铟（TMI）（ H2），精确到0.002％。在的标准epison经营在150托和1200托之间的压力。
