English: 
PQ 
Chinese: 
渗透系数 

Examples: 
1.  A logic operator having the property that if P is a statement, Q is a statement, R is a statement,..., then the AND of P,Q,R... is true if all statements are true, false if any statement is false. P AND Q is often represented by P?Q, PQ, P∧Q. 
 一个具有下列性质的逻辑操作符:如果P是一个语句,Q是一个语句,R是一个语句……那么,当P, Q, R...都为真时,它们的“与”也为真;只要有一个为假,其“与”就为假。P“与”Q常常用P?Q,pq或P∧Q表示。 
2.  A logic operator having the property that if P is a statement, Q is a statement, R is a statement,..., then the AND of P,Q,R... is true if all statements are true, false if any statement is false. P AND Q is often represented by P·Q, PQ, P∧Q. 
 一个具有下列性质的逻辑操作符:如果P是一个语句,Q是一个语句,R是一个语句……那么,当P, Q, R...都为真时,它们的“与”也为真;只要有一个为假,其“与”就为假。P“与”Q常常用P·Q,pq或P∧Q表示。 
3.  According as six national standards for PQ, a PQA( Power Quality Analyzer) based on DSP( Digital Signal Processor) has been designed and developed. 
 依据我国的6项电能质量国家标准,作者设计了一台基于DSP的电能质量分析装置。 
4.  Although PQ is described as a separate activity, it may in some cases be appropriate to perform it in conjunction with OQ. 
 尽管pq被描述为一个独立的活动，但是在某些情况下它会与OQ结合起来。 
5.  It is necessary to monitor and analyze PQ( Power Quality) firstly in order to solve the PQ problems in power system, then the possible reforming project can be put forward for improving power supply quality. 
 解决电力系统的电能质量问题,首先需要对电能质量的各项指标进行全面的监测和分析,在此基础上才能有针对性地改善电能质量。 
6.  This time the PQ's promise to hold another referendum if elected put many voters off, perhaps for good. 
 在这次选举中，魁人党保证如果选举成功，将再次举行全民公投，此举让许多选民背弃该党，有可能是永远的背弃。
