可靠性函数 meaning in English

reliability function

First , the backward kolmogorov equation for the conditional reliability function and the pontryagin equation for mean first - passage time and then - associated boundary and initial conditions are derived based on the stochastic averaging methods for quasi non - integrable , quasi integrable and quasi partially integrable hamiltonian systems , respectively
首先利用拟不可积、拟可积非共振及拟部分可积非共振hamilton系统的随机平均法分别给出了研究该系统首次穿越问题的提法，包括计算条件可靠性函数的后向kolmogorov方程及计算平均首次穿越时间的pontryagin方程及其边值条件。
