1) partially halogenated
部分卤化的 PH
2) pH value of brine
卤水pH值
1.
By identifying the influence of pH value of brine on salt making equipm ent,reaction velocity of brine,sedimentation velocity as well as quality of puri fied brine,this paper puts forward the measures and methods of adjusting the pH value of brine.
通过认识卤水pH值对制盐设备的影响及对卤水反应速度、沉降速度及精卤质量的影响,提出调节控制卤水pH值的措施及方法。
3) pH-partition
pH-分配
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.
考虑由两不同部件组成的并联系统,假定部件的寿命服从指数分布,部件失效后的修理时间服从PH分布,修复如新。
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。
