4) phase type distribution
PH分布
1.
In the system,the life distribution of these two units is assumed to be exponential distribution,the repair distribution is assumed to be phase type distribution,and it is "as good as new" after the failed units repair.

5) Phase-Type distribution
PH分布
1.
Phase-Type distributions have gained widespread attention in the area of stochastic modeling,two primary reasons being their denseness and algorithmic tractability.
Phase-Type(PH)分布具有良好的通用性和易于进行解析处理的特性,因此PH分布已经成为随机模型解析分析的重要工具。
补充资料：pH值
分子式：
CAS号：
性质：H30+浓度的负对数称为pH值。即pH=-1g[H3O+]。如[H3O+]=1.0×10-7mol/dm3，pH=7.00。水溶液的pH的范围在0～14之间，pH为1～7呈酸性，pH为7～14呈碱性。pH=7呈中性。
