求助现在我想在refprop中验证这组程序计算结果是否准确，死活找不到在哪个地方可以输入温度，以及某一相的相态来得到输出结果。想知道这个对应的SATT在refprop中是怎么体现计算出来的呢
//...Get saturation properties given t,x; for i=1: x is liquid phase
//..... for i=2: x is vapor phase
double t = 160.0;
double p, dl, dv;
SATTdll(t, x, i, p, dl, dv, xliq, xvap, ierr, herr, errormessagelength);
printf("P,Dl,Dv,xl[0],xv[0] %10.4f,%10.4f,%10.4f,%10.4f,%10.4f\n", p, dl, dv, xliq[0], xvap[0]);
i = 2;
SATTdll(t, x, i, p, dl, dv, xliq, xvap, ierr, herr, errormessagelength);
printf("P,Dl,Dv,xl[0],xv[0] %10.4f,%10.4f,%10.4f,%10.4f,%10.4f\n", p, dl, dv, xliq[0], xvap[0]);
//...Calculate saturation properties at a given p. i is same as SATT
i = 2;
SATPdll(p, x, i, t, dl, dv, xliq, xvap, ierr, herr, errormessagelength);
printf("T,Dl,Dv,xl(1),xv(1) %10.4f,%10.4f,%10.4f,%10.4f,%10.4f\n", t, dl, dv, xliq[0], xvap[0]);
