Apply GO methodology to analysis the operational reliability of subsystem for fire equipment;

High voltage triggering switch tube is the key component of pulse power device,which has two failure modes:triggering failure and self breakdown Operation of pulse power device would be seriously affected without solving these problems Approaches to solve the failures are introduced to improve the operational reliability of high voltage triggering switch tube in this pape

TThe operational reliability of electronic components is the key and basis for the reliability of the entire equipment.

This article introduces a calculating formula of the passing reliability coefficient of the high-speed rotating moment arm of the combined gear shaft without keys, analyses the factors which impair the reliability, and presents methods which can be used to improve it.

One Way ANOVA is their usual choice, but the method of group discussion must be selected properly, and then the criterion of reliability coefficient must be readjusted appropriately.

Based on the frequency and the population of test,population reliability coefficient and sample reliability coefficient,the reliability theory of measurement in physical education was expounded,under combining with the idea of parameter estimation,the influence on the frequency of test and sample size to the reliability was discussed.

This thesis contributes to the theory and applications of storage-usage reliability model in the storage reliability.
