These phenomena are explained as follows thatduring the hydration of α-hemihydrate gypsum, cations have significance influence on theζpotential of α-hemihydrate gypsum, thereby the dispersed state and the dissolving ratesof α-hemihydrate gypsum are changed. But anions have slight influence because it isdifficult that anions enter the double-layer.

产生这一现象的主要原因是：在α半水石膏的水化硬化过程中，阳离子对α半水石膏的ζ电位产生较大影响，从而改变了α半水石膏颗粒的分散程度和溶解速度；而阴离子很难进入双电层，因此对水化过程的影响较小。
