煤样的制备是煤质分析十分重要的一个环节,要求通过煤样制备取得具有代表性的实验样品,当然也要求流程合理,在保证样品具有代表性的同时保证有一定的工作效率,最近颁发要求在1984年5月实施的国家标准GB474-83《煤样的制备方法》在这方面起了促进作用,但我们认为尚有某些不足和值得进一步研讨地方,现提出以下商榷意见,以便在集思广益的基础上,使之臻于完善。
The preparation of coal samples is a very important part of coal quality analysis. It requires obtaining representative sample samples through coal sample preparation, of course, requires a reasonable process, to ensure that samples are representative while ensuring a certain efficiency. Recently, The national standard GB474-83 “Preparation of coal samples” which was required to be implemented in May 1984 has played a catalytic role in this respect. However, we think there are some shortcomings and areas worth further study. The following opinions are put forward so that Based on brainstorming, make it perfect.
