摘要
按中华人民共和国国家标准《煤的镜质组反射率测定方法》（GB 6948—86）得到同一类正常配煤m个正常配煤反射率直方图,进而得到一个根据m次测试反射率为n,从0.3%～2.1%按半阶分,得活性组分含量的算术平均值x_n的直方草图。因为含量的算术平均值x_n加和一定不是100%,所以必须修正。修正后,得到一个根据m次测试反射率为n,从0.3%～2.1%按半阶分,得活性组分含量的算术平均值x_n的标准直方图。
According to the national standard of the PRC＇s Measurement Method for Coal Vitrinite Reflectance of GB 6948-86,m normal coal-blending reflectance histograms for the same kind of blended coal were obtained,and further a histogram sketch with the reflectivity n based on m tests,half order of 0.3%-2.1%,and arithmetic mean value Xn of active ingredient content was obtained.Because adding the arithmetic mean value of the content must not be 100%,so it must be corrected.After the correction,a standard histogram with the reflectivity n based on m tests,half order of 0.3%-2.1%,and arithmetic mean value Xnof active ingredient content was obtained.
