摘要:利用Monte Carlo技术对升降法试验进行了模拟，通过试验结果对标准差估计值的偏差进行了研究。结果表明：估计值的偏差不是系统地偏小，有时也偏大，它与升降法试验中的步长、每组试验量、刺激量个数等试验参量有关系，其中刺激量个数对其影响较大。刺激量个数为4、5时的估计值基本偏小，个数为6、7时普遍偏大。该分析为利用升降法数据进行可靠性评定打下了基础。
Abstract:The up-down sensitivity test is simulated with Monte Carlo method. The deviation of the estimation value of , the standard deviation, is studied through analysis of the test results, indicating that the estimation value of the is not systematically lower, sometimes, it become much higher than the real value. The estimation value related to the step size, number of tests and number of test stress, especially the number of test stress. If the number is 4 and 5, the value of is generally lower, if the number is 6 and 7, the value become higher. This estimation established a foundation for the reliability assessment with up-down sensitivity data.
