| 摘 要： | The influence of pressure on miscibility behavior of the systems polystyrene/cyclopentan(?)and polystyrene/1-phenyldecane is studied with a modified hole theory.It is found that the pres-sure dependence of excess volume is responsible for the different kinds of behavior of these two sys-tems.Furthermore,the excess volume is decomposed into two separatc parts,one from the contri-bution of cell volume expansion and the other from the change of hole fraction,and their relation-ship with pressure dependence of the miscibility behavior is analysed.
