probability propagation

Second, in order to coordinate the flavor conservation in the weak interaction and the flavor violation in the neutrino propagation, the conventional time-dependent perturbation theory is limited in the calculation of the reaction probability where the neutrino is involved.

其次，为了协调弱作用中代轻子数守恒与中微子传播中代轻子数破坏，通行的含时微扰论在应用到涉及中微子反应的概率计算时会受到限制。

Software defects are inevitable, however, the software reliability is relates to the probability of errors when software is running. Thus, to improve the software reliability, the control of software defects propagation and find error tendency modules are very important.

软件缺陷是不可避免的，而软件的可靠性是软件在运行时错误出现的频率，因此要提高软件的可靠性，其中控制软件缺陷传播、寻找软件的错误倾向模块就显得非常重要。
