Abstract: This paper is a further research of reference [1]. At first, the author analyzes the force-energetics basis of the frozen-wall system. By quantitative discussion of Model(Ⅰ)in reference [1], we get a thermal stability entropy model of the frozen-wall system(called Model(Ⅱ)). At last, we check the models by the field observed data in Anhui Province. P.R.C. The result is greatly satisfactory.
