1·According to the perturbation theory, a distribution law of matrix element in secular equation is discovered in degenerate state and wave function property of the hydrogen atom.

根据简并态微扰理论和氢原子波函数的性质，得到久期方程中微扰矩阵元的分布规律。

2·The condition of this model converge to degenerate normal distribution is discussed by citing the idea of infinitesimal, combining with the law of 0-1.

引用无穷小概念，结合0 - 1律讨论了该模型的分布收敛于退化正态分布的条件。

3·In this paper, the density function of n-dimensional P-norm distribution is derived. Laplace, Normal, Rectangular and Degenerate ones are the specific case of one-dimensional P-norm distribution.

本文构造了n维p -范分布的密度函数，使拉普拉斯分布、正态分布、均匀分布与退化分布均为一维p -范分布的特例。
