21版GEM模型，通过Builder的向导建立表活剂驱模型，DAT文件中生成了*TSORW及*TKRWRO这两个关键字，并且有相应的值（过程向导中未设置这两个值），请问这两个关键字代表什么含义，相应的值怎么计算得来的？

参考用户手册:
TSorwUsed to specify the residual oil saturation, Sorw, of a relative permeability table. This value overrides the value specified with the *SWT table. TSorw is the oil saturation at which oil first becomes mobile in the two phase oil-water table. It is always equal to or greater than TSoirw.Oil wet: Residual water saturation of a grid block. TSorw is the water saturation at which water first becomes mobile in the two phase oil-water table. It is always equal to or greater than TSoirw
