由于缺乏对冰在压力下的实际行为的了解，从理论上描述冰川流动的尝试受到了阻碍，因此在随机取向的多晶冰块上进行了实验。此类块的制备方法以及在 − 1.5°C 下对其进行压缩测试的初步结果。已经被简要报道过1。现在已在 − 12.8°、− 6.7°、− 1.5° 和 − 0.02° C 下进行了进一步的压缩测试。
ATTEMPTS to describe the flow of glaciers theoretically have been hindered by lack of knowledge of the actual behaviour of ice under stress, and for this reason experiments have been made on blocks of polycrystalline ice with random orientation. The method of preparation of such blocks and preliminary results of compression tests on them at − 1.5°C. have already been briefly reported1. Further compression tests have now been made at − 12.8°, − 6.7°, − 1.5° and − 0.02° C.
