本文提出单位体积极化率的概念，并用它作为非极性气体在水中溶解性大小的判据。

The concept of unit volume polarizability is suggested in this paper, it is regarded as a criterion for the solubility magnitude of nonpolar gas in the water.

适当增加压力、升高温度有利于均相体系的形成。剪切作用可提高气体的扩散性和溶解性，同时还可大大缩短均相体系形成所需要的时间。

Shearing may help the diffusion and dissolution of gas in the polymer, and thus may reduce the time for the formation of homogenous system.
