摘要引入了随机变量的截尾和停时的概念，在定理条件及其证明过程中适当地定义随机变量的截尾和停时，并通过定义鞅差序列和利用鞅差序列的收敛定理，得到了一类关于任意随机适应序列的强收敛定理。 - A necessary and sufficient condition with ergodic of 1 - order probability distribution function of stochastic process ( theorem 1 and corollary 1 ) and extended the general distribution theorem of stochastic variable under the case of weakly condition ( theorem2 ) are presented
摘要提出了随机过程一阶概率分布函数具有遍历性的一个充分必要条件（定理1和推论1 ） ，并在较弱条件下，对一般的关于随机变量函数分布定理作了进一步的推广（定理2 ） 。 - Define a random route , which pass through all the grid node , on the condition of given n conditional datum , get a value on the first grid node from the conditional distribution of stochastic variable , add the new value into the conditional datum as a new conditional data . on the condition of current n + 1 conditional datum , get a new value from conditional distribution of stochastic variable on the next node again . then continue until all the nodes gets own value
定义一个经过所有网格节点的随机路径，在给定n个条件数据的情况下，在第一个网格节点处从随机变量的条件分布中抽取一个值，将这个新值加入到条件数据集中，在给定的n + 1个条件数据的情况下，在节点处从随机变量的条件分布中抽取一个值，重新进行，直到所有节点被模拟完为止。 - It has shown by the uncertainty of the data of fatigue experimentation and the size deviation of machine accessory and structure component and the original defect of materials that all of the stress and intensity and the factors that affect them are stochastic variables , so we should deal with the problem of fatigue by the method of probability and statistics to making the engineering life deduced by fatigue intensity to be the reliable life under a certain probability
疲劳试验数据的离散性，零件和构件加工允许的尺寸偏差，材料中分布的原始缺陷，以及受载零件危险部位应力响应的分布特性等，都说明应力和强度以及影响它们的因素都是随机变量，它们有各自的分布形式，应该用概率统计理论和方法来处理，才能使疲劳强度在工程中所确定的寿命，成为保证某一概率下的可靠寿命。 - Based on the theory of stochastic finite element , the structural parameters of frame - shear structure including stiffness and mass and damping are simulated to be stochastic variables . by solving recurrence equation of stochastic finite element , the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame - shear structure . an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame - shear structure . as shown by the results , with regard to frame - shear structure , the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response . variation of stiffness will cause the response of frame - shear structure to variate greatly ; variation of mass shows less effect ; and variation of damping shows insignificant effect . the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone
以随机有限元理论为基础，将框剪结构的刚度、质量、阻尼等结构参数为随机变量.通过求解随机有限元的递推方程，得到框剪结构各层的地震动力响应均值和标准差历时曲线.分析结构参数单独变异，以及同时变异对框剪结构地震响应的影响.研究结果表明,对框剪结构而言，结构参数的变异对响应的均值变化影响都不大，主要是增大响应的标准差.刚度的变异性将引起框剪结构的响应发生大幅度变异，质量的变异性影响稍小，阻尼的变异性影响不显著.结构各参数的同时变异，对框剪结构地震响应的影响，仅比刚度单独变异的影响稍大
