statistical level distribution

The authors suggest two methods for assessing crepe effect of crepe de chine through computer image process and analysis, i. e. grey level histogram-based polytypic analysis and grey level distribution-based statistical analysis.

提出了两种利用计算机图象处理与分析技术评价双绉绉效应的方法，方法一是基于灰度直方图的聚类分析法，方法二是基于灰度分布的统计特征分析法。

The probability functions of carriers occupying the impurity level are calculated by applying the Fermi-Dirac distribution function and the thermal-equilibrium theory of the impurity ionization, the result accord with that obtained by applying the conventional thermodynamic and statistical theory and the method of computing the chemical potential.

利用费米分布函数和杂质电离的热平衡理论计算了载流子在杂质能级上的占据概率，其结果与传统的热力学统计理论及计算化学势方法得到的结果完全一致。

Based on the idea of statistics on the struc-ture, the clique histogram represents the distribution of one vertex with respect to its adjacent vertices, which can capture statistical information on the vertex level.

采用对结构进行统计的思路，首先定义团直方图来表示图的顶点到其邻接顶点之间的分布，捕捉顶点层次上的统计信息。
