我国煤的R_(max)与V_(daf)数据之间的关系

在对我国大量煤样的挥发分与最大平均镜质体反射率数据进行统计分析的基础上,运用数理统计的原理和方法,对数据进行了线性、指数、对数和幂函数模型的拟合,分别建立了它们之间的线性关系式。通过对各模型决定系数、残差平方和、回归平方和均方残差的大小对比,认为数据整体幂函数关系显著,然后对其进行了检验。该关系式能够使我国积累的大量挥发分测试数据发挥它应有的价值,并能减少一些不重要的测试。这对我国煤变质研究,对指导我国煤炭、煤层气资源的合理评价、开发和综合利用,具有一定的实际意义。

Relation between Rmax and Vdaf in China

By the means of the principle and method of the mathematical statistics,and based on statistical analysis of Rmax and Vdaf data,this paper establishes respectively the whole and part related expressions,by linear,exponential,logarithmic and power model.Power function decision coefficient is remarkable,so the whole data of function relation is power function model,according to the result of the verifying relativity.The relational formula make the accumulated massive data display its value and reduce some unimportant test.It is a certain practical significance for the development of coal industry and coalbed gas industry in our country.
