Moreover, step-stress life-testing with random stress-change times is studied because it is more useful in practice.

其中，具有随机应力转换时间的步加寿命试验由于其实用性而更具有研究的意义。

But I want to stress again, as long as I do the base case right and my inductive or recursive step reduces it to a smaller version of the same problem, the code will in fact converge and give me out an answer.

就开心的去做吧,但是我想再次强调,只要基础事件处理正确而我的递归,或递推步骤能把它简化为更简单的同类问题,那么这段代码就可以收敛。
