摘要
采用数理统计中的一元回归分析法,利用发热量与固定碳百分含量的关系及发热量与灰分产率的关系,可以分别对比出5、7两煤层。为童子岩组第三段上亚段各煤层提供了新的对比依据。
This paper is analyzed the relation thermal value with fixed carbon percentage and ash percentage by simple regression analysis of mathematical statistics, stepwised comparision No.5 coal with No.7. It is provided a new contrasting basis for comparison every coal of upper part of No.3 member of Tongziyan formation.
