n.绝对压强(磅/平方时面积)

For ethane, the critical pressure is 707.8 psia. 乙烷的临界压力为707.

Carbon dioxide will convert directly from a liquid to a solid if the liquid is depressurized below76 psia (61 psig). 如果液体压力降到76psia(61psig)以下，直接从液态转化到固态。

Containers used for transporting liquid nitrogen at less than 25 psig (40 psia) pressure are UN/DOT authorized containers. 用于运输压力小于25psig(40psia)的液态氮的容器是UN/DOT认可的容器。

Containers used for transporting liquid nitrogen at pressures greater than 25 psig (40 psia) need to be designed, manufactured, and tested to DOT specifications. 用于运输压力大于25psig(40psia)的液态氮的容器需要按照DOT规范设计、制造和检测。
