共聚硬球链流体的分子热力学模型为基础，通过引入链节间方阱位能相互作用的贡献，建立了实际共以聚高分子系统的分子热力学模型，对纯共聚高分子PVT的关联结果，平均相对误差为0.22%~0.80%。
Based on the molecular thermodynamic model of the copolymer chain-spheroidal fluid, the molecular thermodynamic model of the polymer system is established by introducing the interaction of the square-well energy between the chain links. The average correlation coefficient The relative error is 0.22% ~ 0.80%.
