| Abstract: | Based on the condition that the VFD's(vacuum fluorescent display) life is distributed as lognormal distribution, We gained the VFD's point estimation of the average life, the failure rate and the reliability function based on typeⅡprogressively censored data. Also, the lower confident limits of the reliability function is obtained in this case. Further more, we validated the correctness and feasibility of the conclusions and analyzed them. |
