摘要
本文用统计力学的方法分析了单链晶体的平衡态．通过计算得到平衡态尺寸，平衡态尺寸与温度及单链的分子量有关．从单链晶体的热力学分析也得到了类似的平衡态尺寸表示式．比较两个结果，可从分子理论的基础上来理解单链晶体的侧表面自由能及折迭表面自由能．
A statistical mechanical method is used to analyse the equilibrium state of single-chain crystal. The equilibrium dimension of single-chain crystal is calculated,and it is shown that the equilibrium dimension is related to temperature and the molar mass of single chain. A similar expression is also obtained from the thermodynamics analysis of single-chain. By comparing both results, an explanation of side and fold surface free energies can be found on molecular-theoretical grounds.
