求助 Excel调用refprop临界参数函数应该怎么写，比如临界压力临界温度怎么查

rned in a similar manner via the inputs "crit" or "trip", along with inputs of the fluid name and the units. The molar mass (molecular weight) is returned using the function MolarMass with an input of the fluid name only. All of these functions are shown in the REFPROP.xls file. The latest instructions for permanently linking REFPROP
我知道了 用 crit ，比如临界压力 P=pressure("isopentane","crit","SI") , 结果为 3.378Mpa
isopentane=R601a=异戊烷
