skewed normal distribution meaning in Chinese

非对称正态分布
偏正态分布

In the paper , the main results are brought forth in five aspects as follows : ( 1 ) . the analysis of statistics the characteristic indicated that the variation coefficient of the soil nitrogen density of 0 ~ 30cm depth is lower , the variation coefficient is only 3 . 6 % , the variation coefficient of the nitrogen density of 0 ~ 100cm depth is much bigger than that the 0 ~ 30cm depth , it is 100 % . based on the second national soil general survey material , the average soil profile depth is 101cm , this is in corresponding with skew normal distribution , its standard deviation is 0 . 0192
通过研究，得到以下认识与结果： ( 1 )统计特征分析表明， 0 30cm厚度土壤氮密度的变异系数较低，为3 . 6 ， 0 100cm厚度的氮密度的变异系数相对于来说就很大，为100 ；全国土壤剖面深度平均为101cm ，符合偏正态分布，标准方差为0 . 0192 ； 0 30cm厚度土壤氮密度服从对数正态分布，而0 100cm厚度土壤氮密度基本服从偏正态分布。
