Purpose of this study was determination of grain boundary thickness and etc. using a laser interferometer, and physical properties of ice with fine grain size. Laser interferometer was only carried out stability of equipment. Making of ice samples with fine grain size, 0.01mm order, were success by ice phase transition. Uniaxial creep tests were carried out using the fine grain ice samples. The temperature and stress conditions were test parameters. Strain rate at 10% strain is several 100 times faster than normal grain size ice. And minimum stain rate does not appear for cold temperature test conditions. It normally appears around several present of strain. These result suggest that grain boundary strongly affect to deformation of ice.

这项研究的目的是使用激光干涉仪和晶粒尺寸细小的冰的物理特性确定晶界厚度和等。激光干涉仪仅进行设备的稳定性。通过冰期过渡的成功制作晶粒大小为0.01mm的冰样品是成功的。使用细粒冰样样品进行了单轴蠕变测试。温度和应力条件是测试参数。 10％应变时的应变速率比正常晶粒尺寸冰快100倍。对于冷温度测试条件，没有出现最低污渍速率。它通常出现在菌株的几个现在。这些结果表明，晶界对冰的变形有强烈影响。
