When we determined a group of the attractive interactions " values , we can get some typical phase diagrams between the solid and the liquid . further , considering the molecular fraction q , we can also get some typical phase diagrams of this system between the liquid and the gas
进而考虑到占据率q ，我们又写出了该系统的液-气两相平衡曲线方程的表达式，同样给定势参数，也得到了该系统的几种典型的液气相图。
Because of the existence of the holes in the system , the molecular fraction q should considered into the free energies and the gibbs functions . when there are few holes or none existing in the system , i . e . , , it corresponds to the liquid state or solid state ; when there are lots of holes and a few atoms existing in the system , i . e . , , it corresponding to the gas state
为了进一步研究固、液、气三相之间的转变，我们引入空格点并定义了占据率q ，当空格点几乎没有或很少时，即q 1 ，系统对应的是固态或液态；而当空格点很多时，即q 0系统中原子很少，系统对应的则是气态。
