We have proved that the part sum of this random variable s sequence converges weakly to a random variable which has a nondegenerate distribution.
利用截尾法,研究了一类独立随机变量列的平稳律,在适当的条件下,证明了该随机变量列的部分和弱收敛到一个具有非退化分布的随机变量。
According to the relation between reliability and degradation measure distribution,the corresponding reliability functions were developed.
首先,从性能退化量分布的角度出发,在假设退化量分布类型不随时间变化的前提下,利用时间序列建立了性能退化分布参数的分析模型,进而根据可靠度与性能退化量分布的关系进行可靠性评估。
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。
