摘　　要："金刚石"型四能级光学量子相干系统具有多种可区分的子类型,且有很强的结构多样性。根据偶极跃迁选择规则,适当的选择光学跃迁通道,加上相应的激光场,利用布尔代数方法将"金刚石"型四能级量子相干系统分成9种不同的"现实通道子类型";又根据激光对不同跃迁通道的激发强度的强、弱不同,将现实通道子类型进一步精确分为80种不同的所谓"强度子类型"。主要讨论了"金刚石"型四能级系统的结构多样性,并对某些子类型作出了说明,指出了哪些类型己经在一些领域被研究过,而某些类型即使在理论上也尚未得到研究。There are many distinguishable subtypes of diamond - type four - level optical quantum coherent （OQC） systems, which come with high structural diversity. We selected transition channels properly according to the rules for dipole transition selection. With a corresponding laser field, we used Boolean algebra methods to classify diamond -type four -level OQC systems into nine real -world channel subtypes （RCSs）. Also, we went further by classifying those RCSs into eighty so -called intensity subtypes （ISs） exactly, depending on the excitation intensity of the laser for different transition channels. We focused our discussion on the structural diversity of diamond -type four- level systems, while pointing out which substypes have been studied in some aspects and which ones have not even been theoretically studied.
