Studies on Low Temperature Solid-state Syntheses, Crystal Structures and Third-order Non-Linear Optical ( NLO) Properties of the Homo-( hetero-) nuclear Metal Clusters 金属同(异)核簇合物的低温固相合成、结构及三阶非线性光学性能的研究
The concept of fuzzy homomorphism of fuzzy groups is introduced and the correspondence ( relations) between sub-fuzzy-groups ( normal sub-fuzzy-groups) are obtained under fuzzy homo-( morphism.) Then the fundamental theorem of fuzzy homomorphism is established. 引进模糊群的模糊同态概念,给出模糊同态下子模糊群(正规子模糊群)间的对应关系,建立模糊群的模糊同态基本定理,同时讨论模糊群的若干性质,得到一系列等价条件。
The HOMO-LUMO energies of these clusters have also calculated. 同时,对上述团簇的HOMO-LUMO能量间隔进行了计算。
Fluorescence Resonance Energy Transfer Assay: Applications in The Study of Protein-protein Interaction Detection of the Homo-or Hetero-interaction of Doks with Fluorescence Resonance Energy Transfer in Living Cells FRET技术及其在蛋白质-蛋白质分子相互作用研究中的应用应用荧光共振能量转移技术研究Dok分子的异源及同源相互作用
It is found that the conjugated plane made up of the amine group and benzene ring is of the active position, and HOMO and LUMO of eight compounds are π-molecular orbital with lone pare electron. 研究表明,这些添加剂胺基和苯环形成的共轭平面构成了活性部位,其HOMO和LUMO均为π-分子轨道。
We extended Torrey's theory, based on the model of random walk to nearest neighbor sites for homonuclear dipolar interaction, to the case that both homo-and heteronuclear interactions are existent. 我们把Torrey同核偶极作用近邻无规扩散行步理论推广到同核、异核偶极作用并存的情况;
"Homo Oeconomicus" s morals are built mainly through moral education, legal system and self-efforts to perfect, to promote the realization of "realistic morals people". 经济人的道德建设主要通过道德教育、完善的法律制度以及自我的努力,来促进现实道德人的实现。
The Petroleum fermentation Nylon ( PF Nylon) is the name of a series products of homo-and co-polymers Nylon, which consists of single or mixed dibasic acids made from petroleum by-products, light paraffins. 石油发酵尼龙(简称PF尼龙)是用石油副产品轻蜡发酵得到的单一或混合二元酸制成的一系列新型均聚和共聚尼龙的总称。
In order to improve the hole mobility of PT and lower the HOMO and broaden the absorption spectrum, a novel conjugated polymer, poly ( thienylene-vinylene-thienylene) with cyano substituent ( CN-PTVT) was synthesized. 为进一步有效地提高聚噻吩的空穴迁移率、降低聚合物的HOMO能级以及拓宽聚合物的吸收光谱,设计合成了一种新型的腈基取代的聚(噻吩-乙烯-噻吩)的聚合物CN-PTVT。
It is found that the introduction of substituents can enlarge π-conjugation of the molecule and improve the HOMO and LUMO levels, resulting in the red-shift of absorption. 研究发现不同取代基的引入导致分子结构产生不同程度的扭曲。引入取代基后,分子的共轭程度增加,HOMO、LUMO都降低,配合物的吸收红移。
