摘　　要：描述了细粒酒精模型冰特征长度和变形模量的测试理论基础和方法，给出了实际测量结果并对该方法存在的问题进行了讨论。简述了试验过程中发生蠕变的事实并给出最佳试验砝码质量和试验方法。另外，还给出了特征长度、变形模量与冰密度和未冻液体含量的试验关系。The theoretical basement and methods for the measurement of the characteristic length and strain modulus of the fine grain ethanol model ice were described. The measured results and problems in the tested manner were discussed. The fact of creep in the test process and the best loaded mass and tested procedures are stated. In addition, the experimental relationships of the characteristic length, strain modulus and density, content of the unfrozen solution were given.
