摘要
为了探究磁场对水及盐溶液的冻结影响,我们在不同的磁场强度下,观察水及其盐溶液冻结的显微图像,进行图像对比,理论分析;可以得出磁场的作用可以降低水及其盐溶液的过冷度,并且在磁场的作用下可以使冻结过程中所形成冰晶小于无磁场的。为冻结食物提供参考。
in order to explore the magnetic field on the water and salt solution the effect of freezing,we under different magnetic field intensities,observation of freezing water and the aqueous solution of the microscopic image,image contrast,theoretical analysis;can it is concluded that the effect of the magnetic field can reduce the water and the aqueous solution of super cooling,and under the action of the magnetic field can make the freeze in the process of the formation of ice crystals is less than in the absence of the magnetic field Provide reference for freezing food
