stochastic variable meaning in English
随机变量
随机变数
Examples
- Then combined with reliability computation , the stochastic finite element method is used to establish the relationship between the load effect ( stress or force ) and basic stochastic variable dealing with statistical features of variables
再与可靠度理论相结合，考虑变量的随机特性，通过随机有限元法建立荷载效应（如应力、内力等）与基本随机变量之间的关系。 - The equation of the structural limiting state can be expressed : z = r - s , thereinto r and s respectively are structural resistance and load response expressed with stochastic variables , we ca
结构的极限状态方程可以表示为： z = r ? s ，其中r和s分别为用随机变量表示的结构的抗力和荷载响应，通过极限状态方程就可以得出结构的失效概率，或者是用可靠指标表示的结构的可靠度。 - For the uncertain character of material function , the intensity of spray concrete and concrete lining is uncertain too . it can describe quality character better by probability model and statistic parameter of stochastic variable
由于材料性能具有不确定性，喷混凝土和二次衬砌的强度亦同样具有不确定性，一般用随机变量的概率模型和统计参数来描述，能更好地描述其质量特征。 - This paper proved that in the optimal models with stochastic variables , if the parameter estimation and the optimal solution are separated , the optimal result in practice is bound to be less than that in theory
摘要证明了在涉及随机变量的最优化模型中，如果将参数估计和最优化求解过程分离，实际得到的最优化结果必然低于理论值，即参数估计在最优化模型中总是造成低效的结果。
