中文摘要：

在用D-T中子发生器分析煤质时,为寻找煤炭所在区域的快中子通量、热中子通量与煤炭元素含量间的关系,文中用MCNP-4C程序模拟了30个煤炭样品,并用多元线性回归找出此关系。由计算结果可知,此关系可用于中子通量的修订,并提高煤炭主要元素含量的测量精度。

英文摘要：

Analyzing coal quality by a D-T generator,we simulate thirty coal samples with MCNP-4C code in order to obtain the relationship among the fluxes of fast neutron,thermal neutron and the contents of main elements in coal.The relationship is worked out by means of multiple linear regressions analysis.The results show that the relationship can be used to revise the fluxes of fast neutron,so the measurement accuracy of the main elements in the coal is improved.
