satisfy the normal distribution

It is shown that the ice thickness and the ice velocity satisfy with Lognormal distribution and Rayleigh distribution respectively, and that the ice compression strength obeys normal distribution.

结果表明：冰厚和冰速分别服从对数正态分布和瑞利分布，海冰压缩强度服从正态分布。

However, in practice many parameters do not satisfy those hypothesized distribution. In order to handle the defect of normal heteroscedasticity testing means, we pose a new mean, that is runs test.

但实际研究中往往有很多参数不服从假设的分布，针对这一以往方法的缺陷，提出了异方差的游程检验方法。
