报告摘要：第一部分讲当时的时代背景，一分为二等；成就与战略失误就是在束缚态问题上的失误；我的贡献，还要回答虽然我提出了新量子数并要建立像电磁场那样的理论，为何而最后并没有建立起来等等问题。第二部分想借层子模型在束缚态问题上的失误，说明缚态问题的复杂性。首先要指出薛定格方程处理氢原子光谱不太好，但也不能认为狄拉克的理论就满足了相对论的全部要求，这是误解，实质上它并不协变因为他用到了位势；而且不仅是原子物理，包括固体物理，凡是用到位势概念的地方都有可能已经设定了光速无穷大，所以才有不论电子运动范围有多大均可以把波函数归一化的结论。从超精细结构的理论计算，我认束缚态不可能是定域问题，正如狄拉克所说引力场的能量不可能是定域的一样。报告人简介：1934年生，籍贯河南省，唐河县。1952年入北京大学物理系理论物理专业。1956年入原科学院原子能研究所，任实习研究员。1958年入中国科技大学，历任助教，讲师，副教授，教授1970年随学校搬迁安徽，曾在巢湖劳改农场劳动。2000年退休。　　职业领域上，刘耀阳教过中学数学，普通物理，量子力学，量子场论，广义相对论。1957年有幸正遇宇称不守恒发现之际，进行专业调研，自此走上粒子物理理论研究之路，写过一些这方面的文章。参加了上世纪六十年代層子模型研究，并首次明确提出要建立今天称之为色的规范理论。刘耀阳教授是近代物理系理论物理专业创始人之一。
