The K/S value of the polyester fabrics increases when increasing the temperature or the pressure, which have nothing to do with the solubility of the dye. It was observed that C.
聚酯织物的K/S值在实验范围内随系统温度、压力的提高而增加，而与染料溶解度的相对大小无关；

The methods of measuring the biological value of feed phosphorus including balance experiment, slope rate method, tri - index method, in vitro solubility and in vitro dialyse methods were reviewed.
Equations of three dimension solubility parameter of alkyd resin calculated from its oil length are derived. The calculated results are close to the practical value.
