Let X(1),…,X(n) denote the order statistics of a random sample,X1,…,Xnfrom a continuous population.设X(1),…,X(n)是来自于一个连续分布总体的随机样本X1,…,Xn的秩序统计量,给出了任意两个秩序统计量的联合分布函数和联合密度函数的推导证明,从而为其进一步应用打下了基础。
The random samples possesses the same statistical characteristics.结果表明:随机相位角、功率谱密度等级分别影响路面谱激励的样本形状和幅值大小,不同随机样本具备相同统计特征;对于系统的响应曲线,路面平整度等级对幅值影响相对显著,车速变化对形状影响相对显著;根据算例中不同路面平整度等级的计算结果,给出了相应的工程建议。
