The expression, conformed to mixed rule, of upper (n→) or lower (n=1) bound value was also derived on the basis of limit analysis. 收稿日期: 1986-02-18      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 李中华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I2/87 1 Kameswararao, C.V.S., Eng.
