摘要在-7℃附近对人工和天然多晶冰进行了单轴压缩蠕变试验。粒径范围为1 ~ 10 mm。与先前的结果相反，永久蠕变速率没有随着晶体尺寸的增加而增加。只有瞬态蠕变对晶体尺寸的变化敏感。
Abstract Uniaxial compression creep tests were performed on artificial and natural polycrystalline ices at temperatures near –7°C. The grain-size range investigated was from 1 to 10 mm. Contrary to previous results, the permanent creep-rate was not found to increase with crystal size. Only the transient creep appears to be sensitive to variations in crystal size.
