The results show that the structural relaxation may consist of two steps: the low temperature (below 500K)structural relaxation governed by TSRO and the high temperature (above 500K) one governed by both CSRO and TSRO. The activation energy of low temperature structural relaxation is about 17 kJ/mol. 收稿日期: 1987-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 蒋方忻 徐炎 杨国斌 李阳 傅秋南 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I5/495 1 Egami T.
