With the increase of arm numbers of PEG, the temperature of the melting peak of dried gels and the swelling ratio of hydrogels decrease;
随着PEG臂数的增加，干胶的熔融峰顶温度下降，凝胶的溶胀比减小；
The equilibrium swelling ratio of the complex gel was increased gradually with the increase of the reaction temperature, but KGM content had little effect on it.
凝胶的平衡溶胀比随着反应温度的升高逐渐增加，而KGM含量对凝胶平衡溶胀比影响不大；
The increase of the dry density results in the decrease of the ratio of horizontal and vertical swelling pressures.
当干密度较小时，竖向膨胀力与水平膨胀力基本相等；
