基于不完全晶体的热缺陷统计理论,将液体晶格中被占座席分率表示为对比温度的指数函数,推出了一个适用于聚合物,链状大分子及有机溶剂的液体状态方程。将此简化了的状态方程用于17种大分子链烃及10种常见的有机溶剂P-V-T计算,结果与实验值十分相符。与Simha和Somcynsky的空穴理论状态方程式相比较,计算大为简化且精度相当,易于应用至混合物体系。
Based on the statistics theory of incomplete thermal defects, a new equation of liquid state for polymer, chain-like macromolecule and organic solvent is proposed by expressing the proportion of occupied seats in the liquid crystal lattice as an exponential function of contrast temperature. The simplified equation of state was used for the calculation of 17 kinds of macromolecular chain hydrocarbons and 10 common organic solvents P-V-T. The results are in good agreement with the experimental values. Compared with the hole theoretical state equations of Simha and Somcynsky, the calculations are greatly simplified and of comparable precision and are easy to apply to the mixture system.
