| Abstract: | This article compares the efficiency of the step-down-stress ALT and the step-down-stress ALT on the Weibull distribution and the lognormal distribution occasions, respectively by Monte-Carlo simulation. Thus we obtain a condition on which the step-down-stress ALT is better than the step-down-stress ALT. |

| Keywords: | step-down-stress ALT step-down-stress ALT Weibull distribution lognormal distribution efficiency |
