变量;变率
Based on above results, the rule of point variability, spatial variability and distributing probability model of shear strength indexes for several soil layers is obtained, and also some variation laws of the probability characteristic of strength indexes and statistic parameters are obtained.
在此基础上,对几个土层抗剪强度指标的点变异性、空间变异性及分布概型进行了研究,得到了强度指标概率特征及统计参数的变化规律。
