A set of curves concerning initial irreversible loss, irreversible lossduring long-term(up to 10000h) aging and total loss (including both reversibleand irreversible) under certain elevated temperatures (e.g.250℃) against H_(ci) andH_k has been plotted. 收稿日期: 1979-03-18      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 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I3/362 [1] Mildrum, H.
