This paper measures the probability fatigue life of steel wh530 and steel wh6 1 odl which come from wuhan steel and iron company and make out their p - s - n curve based on the basic principle of probability fatigue
本文运用概率疲劳的基本原理，对武汉钢铁公司wdl钢种中的wh530钢和wh610d2钢的标准疲劳试样，通过成组试验方法，测定上述两种材料的概率疲劳寿命，分别做出他们的p - s - n曲线。
I cannot always explain such specific incidents , but a principle of probability called the law of large numbers shows that an event with a low probability of occurrence in a small number of trials has a high probability of occurrence in a large number of trials
我无法针对这些个案一一解释，但有一个称为大数法则的机率原则告诉我们：在数量样本较少时机率很小的事件，在数量样本较大时，其发生的机率便会变高。
