基于超图的产品族结构模型的研究

产品族结构模型是对系列化和组合产品各种复杂关系的综合和表达，它的合理性是产品配置设计过程的基础，超图能够表达是一般离散结构，而结构化超图表达了集合元素之间的层次关系，利用结构化超图模型来构造产品族结构模型，并给出了配置设计算法，最后用一个实例来验证方法的可行性。     

Calorimetric determination of the enthalpy change for the binding of methyl orange to poly(vinylpyrrolidone) in aqueous solution

Thermodynamic parameters have been determined for the interaction of methyl orange and poly(vinylpyrrolidone) in aqueous solutions containing tris, tris and hydrochloric acid, or water only. Enthalpy changes were determined by use of a flow microcalorimeter. Free energy changes were calculated from the results of equilbrium dialysis studies. The results are interpreted in terms of the behaviour of poly(vinylpyrrolidone) in these systems. Analysis of data shows that the hydrophobic interactions in the systems are in the order: tris > wateronly > tris-HC1.
