The d orbital energy levels in triprismatic and octahedral coordinate structures and the intermediate states between triprismatic and octahedral coordinate structures have been calculated by using Angular Overlap Model (AOM). 采用角重叠理论的方法,计算了三棱柱和八面体以及介于两者之间配体场的d轨道分裂后的能级,由此解释了造成JahnTeller效应的原因是键角的变化,而非键长的变 2)  theory of superposition 重叠理论 3)  resonance overlap theory 共振重叠理论 4)  overlap angle 重叠角 1. During the simulation to the mathematical model, the influence of the commuting angle to the electrical current, to the overlap angle and to the electromagnetism efficiency is emphasized. 在数学模型的仿真求解中 ,着重分析了切换角对绕组电流、换流重叠角、电磁效率的影 2. Takong account of the effects of control angle on the converting current and the relations between the transformer impedances and the control angle, overlap angle, conclutions can be obtained that deep controlls of thyristors would make overlap angle decreasing, so that harmonics and losses increased. 从控制角α对变流电流的影响、控制角和换向重叠角与变压器阻抗的关系，得出了在深控时重叠角γ减小，导致交流电流谐波分量增加，增加了涡流损耗和附加损耗；而增大变压器阻抗可增大重叠角和减小损耗等。 3.

Firstly,this paper clarifies the similarities and differences among the nine most popular participant roles in English and in Chinese;secondly,it expounds the two hierarchies of thematic roles and the overlap of thematic roles;thirdly,it points out the importance of thematic analysis. 本文首先从汉语和英语两个不同的角度分析九种最常见的参加者角色的异同,接着阐明了参加者角色的两个等级结构以及角色重叠现象,最后指出角色分析的重要性。 6)  Corner-overlap 角部重叠 1. Analysis and Extra-limit Determining of Corner-overlap Frame Structure 角部重叠框架结构的抗震分析及超限界定 补充资料：角重叠模型 分子式：CAS号：性质：处理配位化合物中金属原子与配体成键作用的一种理论。它以分子轨道理论为基础，保留过渡金属的一个d轨道与一个配体的σ或π轨道组合成一个成键分子轨道和一个反键分子轨道。成键分子轨道比原组合轨道能量低，反键分子轨道比原组合轨道能量高，并假设成键分子轨道能量的降低值与反键分子轨道能量的上升值相等。强调成键分子轨道主要由配体轨道组成，反键分子轨道主要由过渡金属的d轨道组成。但它把分子轨道能量参数化，用角重叠参数eσ或eπ描述金属与配体的σ或π缝合的能量变化和稳定化能。对配位化合物的反应活性、磁性、几何构型与dn轨道的关系等得出比较满意的结果。 说明：补充资料仅用于学习参考，请勿用于其它任何用途。 参考词条 ©2011 dictall.com
