It was found that among the nine possible match groups of the physical broadening function, f(x), with the geometric broadening function, g(x), the correctional formulae for the geometric broadening of five outstanding ones, i. e. G-C, C-G, G-CC, CC-G or CC-CC, were improved with more simplicity, high accuracy and easy on-line applicability. 收稿日期: 1984-06-18      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 白埃民 何崇智 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I6/471 1 #12 2 Klug, H.
