This paper presents an optimization of centered finite-difference operator based on the principle of constrained cost function, which can reduce the truncation error to minimum.
作者根据约束性代价函数原理提出了能够使得截断误差最小化的中心差分优化算子。

Because some products show no failure in the random truncation test period, this paper USES the mean rank order method to calculate the empirical cumulative distribution function.
考虑随机截尾试验中有些试验产品无故障数据出现，提出采用平均秩次法计算经验分布函数。
