labor的翻译? Time for analysis is dependent on the analyzer used, the sample stream being analyzed and the condition of the sample stream at the time of analysis. In general, the elapsed time will be less than 0.02 hour and the labor requirement is 0 hour. 这是关于化工实验的。最后一句里面的labor是什么意思啊? elapsed time 和labor的区别是什么? 谢谢。查看更多2个回答 . 1人已关注
