Abstract

The velocity of ice crystallization in gelled systems was compared with that in solutions of similar macromolecular materials. Neither the constituting material nor the dimensions of the tubes in which the measurements were made influenced the results. The velocity of linear crystallization of ice was slowed in macromolecular solutions and gels, and this decrease was not associated with changes in dynamic or thermodynamic properties of water. It was probably the consequence of a mechanical effect of the macromolecules directly on ice crystal growth.

摘要

将凝胶体系中冰结晶的速度与类似大分子材料溶液中的冰结晶速度进行了比较。无论是构成材料还是进行测量的管子尺寸都不会影响结果。在大分子溶液和凝胶中，冰的线性结晶速度减慢，并且这种降低与水的动力学或热力学性质的变化无关。这可能是大分子直接对冰晶生长产生机械作用的结果。
