起防止冻结作用的 cryoprotective
Research on the experimentation of the different dry density,water content soil sample install with grid. The result showed that whether or not install the grid,The dry density,water content,freezing time isn't influence the regular of the moisture movement.
进一步配制不同密度、不同初始含水量土样并设置格栅进行试验研究,发现无论是否设置格栅,土样密度、含水量、时间对冻结作用导致的水分迁移进程的影响规律是相同的。

冻结滞水指因冬季的冻结作用在包气带冻土层内形成的季节性固态地下水。
The frozen perched groundwater is the seasonal soild state groundwater formed in the aeration frozen layer as a result of winter freezing.
降水通常是由雨滴的合并作用引起的小雨或毛毛雨，因为冻结高度比较多地倾向于在逆温层之上，尤其是在夏季。
Precipitation is usually light rain or drizzle formed by coalescence since the freezing level tends to be above the inversion layer , particularly in summer.
冰川积累区的成冰，主要是当年积雪以融化-再冻结为主要变质成冰作用，平衡线以上附加冰带宽阔；
The main process of ice formation is the metamorphism from melting-refreezing of the seasonally accumulated snow, therefore there exists a broad belt of superimposed ice.
