Asymptotically normal random variable 漸近正規(guī)隨機變量
Bivariate normal random variable 二元正態(tài)隨機變量
Equality condition of retaining the independence of normal random variables under linear transformation 正態(tài)隨機向量線性變換獨立不變性的充要條件
In enforcement plan , the beam and protect plate , and random resistance are analyzed , in which the normal random variable and maximum stress element as evaluation standard are considered 研究了爐墻的改造,梁和護板的改造、腐蝕嚴重的部位的加固方案,分析了梁、柱改造方案的隨機抗力。
Based on the approach of turning some of the relevant extreme - value - type and logarithmic normal distribution variables into independent and normal random variables , the shear - slipping failure probability of a high arch dam is worked out to be of the order of magnitude of 10 ^ ( - 5 ) by means of second - order moment method 在將部分相關的極值型與對數正態(tài)分布隨機變量轉換為獨立、正態(tài)隨機變量的基礎上,利用二階矩法計算得到某高拱壩的剪滑失效概率為10 ^ ( - 5 )量級。
