A lognormal distribution model was used to fit the mite species abundance.
革螨种多度分布用对数正态分布模型拟合。
In the statistical analyses, the result shows that the lognormal distribution model is more suitable for the index of deflection.
同时从统计分析中可知，对数正态分布模型更适合于弯沉指标。
Thus, when the permeability of 50% probability and the coefficient of variation for lognormal distribution are known, one can establish a definite numerical model of permeability plane distribution.
这样，知道模型的渗透率对数正态分布概率50%处渗透率和变异系数，就可以建立起确切的渗透率平面模型。
