【摘要】 电气和机械产品现场可靠性数据处理过程中，常遇到因大量信息中途丢失而被迫截尾的现象．经过用数字仿真的方法对几种常用的方法进行比较分析，找出了处理大截尾比时较好的方法—改进后的修正法．仿真结果表明，用改进后的方法处理现场数据，结果更符合实际情况，应用范围更广．更多还原

【Abstract】 In calculating reliability data of electrical and mechanical products,it is often occurred that large amount of data is lost and truncated.In this paper,several estimating methods are analysed with Monte Carlo simulation,and the modified method,which is better in processing data of large DN,is adjusted.The simulation results show that the processed data is in accordance with practice.更多还原
