Aspen中的stdvol和volune之间的关系

关于Aspen plus中stdvol和volume之间的关系，之前查阅资料，网上说法：stdvol表示标准状态下的体积流量，volume为当前输入状态下的体积流量
但我用aspen模拟，输入温度压力条件为1atm，0℃，然后分别输入stdvol：100cum/h，volume：100cum/h，得到的模拟结果中有两个不同结果的流量，请问是我模拟中输入有错误还是这个说法本身就不对？

The standard liquid volume flow (Stdvol-Flow) can be very different from the volumetric flow rate of a stream. The standard liquid volume is defined at approximately 60F and 1 atm. The difference increases as the conditions diverge from 60F and 1 atm. If the stream is a vapor or has a significant amount of vapor, the volumetric flow rate of a stream is extremely different from the standard liquid volume flow. You can enter standard vapor volume flows as mole-flow. Select the appropriate units.

To report the Std.liq. Volume Flow or Std.liq.Volume Fraction in the stream report, select the appropriate options on the Setup ReportOptions Stream sheet. You can also calculate these Property Sets:

?VLSTDMX (standard liquid volume of a mixture)

?VLSTD (standard liquid volume of a component)

StdVol-Flow and StdVol-Frac are accessible variables that can be used in design specifications and Calculator blocks.

stdvol和vol是有不同的，前者好像指60F下对应的液态的体积流量，而后面指的就是相应状况下的流量。你可以查看帮助文件
