1·Thermal activation is a good method to increase the amount of 4-coordinated al and to improve gelatification activation of gangue.

通过热活化手段增加煤矸石中四配位铝含量可以提高煤矸石胶凝性能。

2·Pectin with high molecular weight can be used to prepare supersonic centrifuge membrane and electric osmotic membrane because of its better gelatification.

高分子量果胶因具有良好的胶凝特性，可用于制备超速离心膜和电渗析膜。

3·The resistance and mass transfer property of ultrafiltration are analyzed, and the modified model of gelatification and polarization is established for the ultrafiltration process.

同时对超滤过程的阻力及传质特性进行分析，并建立超滤过程的修正凝胶极化模型。
