The energy consumed totally may be consi-dered to consist of two portions: i.e., with fresh crack surfaces growth and withcrack propagation. The expression proposed seems to be an advance over previousconventional ones, especially that from the viewpoint of energy distribution. Key words： ore comminution    continuous damage    critical perfectness    damage factor 收稿日期: 1990-03-18      基金资助:国家自然科学基金 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 朱毅 徐小荷 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I3/81 1 Zhu Yi, Xu Xiao-he.
