The probability of the failure depends on the time between marshaling the delegate and the callback on the function pointer as well as the frequency of garbage collections.

该故障发生的可能性取决于从封送委托到对函数指针发出回调之间的时间以及垃圾回收的频率。

Using Markov renewal theory we obtain some indexes such as the system availability, failure frequency and reliability function.

利用马尔可夫更新理论，得到了系统的可用度，故障频度 和可靠度等各项指标。
