Abstract
Three groups of lifetime test were completed, according to the statistical knowledge, the degradation model of cm-bars is obtained using the short-term working datas, then we obtain the extrapolated lifetime of cm-bars at 25°C is 7950 hours (2.86×109 shots), and we also obtain an acceleration factor 1.88 of resulting in a thermal activation energy of Ea=0.21eV using Arrhenius function.
