摘　　要：针对要验证系统是否达到其规定可用性要求的工程需求,阐述了系统可用性鉴定试验的数学原理,给出了系统可用时间和不可用时间均为伽玛分布情形下的定数、定时可用性鉴定试验方案,并简述了可用性鉴定试验的实施要求,对于系统可用性鉴定试验的开展具有一定的参考意义。Aiming at the engineering requirements to verify whether the system meets its specified availability requirements,the mathematical principle of the system availability qualification test is expounded,and the fixed number and fixed time availability test plans when both the available and unavailable time of the system are Gamma distoibution are given,and the implementation requirements of the availability qualification test are briefly described,which has certain reference significance for the development of system availability qualification test.

关 键 词：可用性 鉴定试验 伽玛分布 定数试验方案 定时试验方案
