| 摘 要： | 本文通过对廖炯生提出的ＩＵＭＶＥ法的变差系数公式进行校正，重新对二部件串联系统的可靠性置信下限进行了计算，不仅消除掉大部分非正常点，而且也使计算结果更加合理，但仍存在着９个非正常点。我们利用系统的等价试验信息来消除非正常点，获得了令人满意的结果。

| Abstract: | The lower confidence limits of reliability in series systems composed of two binomial components are calculated by using IUMVE method and the corrected variation coefficient formula.The number of unreasonable results of confidence limit is greatly reduced,but there are still nine unreasonable results.These unreasonable results have been eliminated by introducing a new ordering function including the system equivalent test number and recalculating confidence limits of the nine test result vectors. |
