论述了西德煤矿关于 CH_4及 CO 的测定任务与依据的概要,以及研制的2～3种连续的或准备连续的固定式测定装置。利用集中红外线分析原理操作的装置为最好。Essen-Kray 煤矿研究所研究的 Unor 装置具有很好的测定效果,可以很好地调正到适合矿井条件程度。
The summary of the task and basis of determination of CH_4 and CO in West Germany Coal Mine and the development of 2-3 kinds of continuous or prepared continuous measuring devices are discussed. The device that uses the principle of concentrated infrared analysis is the best. The Unor device studied by the Essen-Kray Institute of Coal Mine has a very good measurement and can be well tuned to suit the conditions of the mine.
