联合概率密度 joint probability density
- 本文在介绍一种修正的联合概率密度函数的基础上,采用有限元法和退火进化算法相结合来研究结构的模糊可靠度。
In this paper, a finite element method and a simulated annealing-genetic algorithm are proposed to determine the structural fuzzy reliability. - 与前人的研究相比,该模型不需要规定时间的长度,可以将影响风蚀的不同因素分为不同的类别,以便进行单一风蚀因子影响分析或通过求出各因子之间的联合概率密度分布而进行综合分析。
And through those can analysis for single fa ctor or through calculating the joint probability density distributions of those factors and analysis the relationships of those factors synthetically.
