Preliminary study on meso-damage propagation characteristics of rock under condition of freezing temperature;

CT scanning test of meso-damage propagation of rock under different freezing temperature;

Effect of different factors on the freezing temperature of shallow top soil

The freezing rate in different conditions was calculated.

This paper investigated effects of CaCl\-2 pre\|treatment,different blanching technologies and freezing rates on the texture of potatoes,and found that CaCl\-2 pretreatment,low\|temperature\|blanching and quick\|freezing were effective in improving the texture of frozen potatoes.

Thus,it is very important to study the damage CT values of rock subjected to different freezing rates.

Experimental analysis on the frozen temperature of typical soil of Bao-Lan railway frozen section;

The frozen temperatures of cow colostrum were measured under both the normal pressure and the low pressure.

This text get the compression strength variety regulation of artificial frozen silty clay along with frozen temperature and moisture content by the compression strength experiment in different temperature and moisture content,and the result has some certain reference value to the design and construction of frozen engineering.
