糖类在水中偏摩尔体积的计算

The Dilute Partial Molar Volume of Carbohydrates in Water

对作者提出的基团贡献模型进行改进,增加了基团相互作用贡献项。用改进后的模型计算了六十种糖类298.15K 在水中的无限稀偏摩尔体积,计算值与实验值的平均绝对偏差为1.53cm^(-1).mol^(-1)。用此模型还能计算淀粉在水中的无限稀偏摩尔体积。

A modification for group contribution model has been achieved by adding group at-tractive term.By using the modified model,the dilute partial molar volumes of 60carbohydrates in water at 298.15K had been calculated.The average absolute error is1.53cm^3.mol^(-1).In addition,the dilute partial molar volume of starch in water was calculatedby using this model.
