摘　　要：本文依据经过评选的４４１种物质的实验数据，建立了由基团贡献概念估算溶度参数的方法。９８个基团的贡献值由实验数据回归求得。本方法对上述４４１个实验点的绝对平均误差为２．３％。A group-contribution technique was proposed for predicting solubility parameter.98 group increments were determined by regression of 441 experimental data,which were carefully selected from a large database. The average absolute deviation for the 441 experi-mental data is 2.3%.
