HYSYS相图Curve数据? 这个是帮助上的解释哦 pt envelope the vapour-liquid envelope for a quality of 1.0 automatically appears. this is actually represented by two curves; one with a vapor fraction of 1.0 and the other having a liquid fraction of 1.0. these curves meet at the stream’s critical point. you can plot additional envelopes for different qualities by typing the desired quality (between 0 and 1) in the quality 1 and quality 2 fields. pt相包线 翻译以下,气液包线是以气液相=1自动呈现,实际上包含两条曲线,一条是气相分率为1,另一条是液相分率为1。这些曲线在流体的临界点相交。你在quality1和quality2输入需要的数据(0-1之间)可以画出另外的相包线。查看更多
