图2 年平均气温为-3 ℃及Ta =15 ℃时温度随时间和深度的变化［灰色阴影为寒冻风化窗所在范围（温度在-3~-8 ℃时），垂直的黑色虚线为0 ℃所在位置；紫色实线（t=182）代表温度随深度的非单调变化］

Fig. 2 Schematic representation of the temperature variation as a function of depth using TMA of -3 °C and Ta of 15 °C ［The grey shadow represents the frost cracking window， between -3 and -8 °C； The black dashed line represents the location of 0 °C； The purple line （t=182） is an example of a depth profile with two 0 °C locations and an inflection point］
