The efficiency and effectiveness were discussed and evaluated by the theory of total non-determinative degree and the relationships between the confidence limit and the precision for the method of drawing samples.

利用置信度和精确度的关系以及总不确定度的理论，对该方法的有效性进行了讨论与评定。

However, we could of course be as wrong about aging as Nixon was in 1971 about cancer, which is why my upper confidence limit is as large as 100 years.

当然，我关于老化的想法也可能像尼克讼1971年关于癌症的想法一样错误，这就是为什么我把上限设置到100年之久。

In the past, the confidence limit problem of three-parameter Weibull distribution has not been solved, so that the creditability of its result can not be guaranteed, that is, only the result that its creditability is equal to 50% can be obtained using old methods.

由于以往三参数威布尔分布的置信度问题一直没有解决，所以其结果的可信程度也就无法得到保证。此时，也可以说它只能给出可信程度为50％的结果。

Weibull distribution is widely used as a life distribution, and estimating lower confidence limit of reliability is important. But so far this problem has not been well solved if when the sample size is small.

威布尔分布是使用非常广泛的寿命分布，关于威布尔分布的可靠度的下限估计是一个有重要意义的问题，文献中有很多讨论，但当样本量较小时，关于二参数威布尔分布的可靠度的下限估计至今没有非常有效的方法。

最后，介绍了本文的主要创新点：(1)提出了先验分布、多层先验分布的构造方法——减函数法、增函数法，并给出了它们在无失效数据问题中的应用。

The declining of confidence limit is the reason that makes the multiple-regression model not to fit for better precision any more.

而多元线性回归分析方法，在更高分辨率的空间插值中，由于测站数目相对减少，可能导致回归可信度下降而使该方法不再适用。
