This thesis is based on the Gini coefficientofconcentration of credit indicators model, and the simple data extreme measure is replaced by introducing of full-calibre data.
论文构建基于基尼系数的信贷集中度指标，通过引入全口径数据取代简单极值数据进行测度。

It includes the concept of stress correction coefficient, a new method to determine the stress concentration factor of mortise of a disk and a new method for correcting the stress ratio.
Then this paper studied the effect of diffusion coefficient on concentration distribution and the conditions of substitution with numerical dispersion for physical diffusion.
