AlN 〓 has the maximal ionization power (9. 14eV) and the minimal electron affinity energy (0.19eV), which manifests that the 〓 is more stable than other clusters, and this conclusions are in good agreement with the experimental results of flight of time mass spectrum .

〓团簇具有最大的电离能（9.14eV）和最小的电子亲和能（0.19eV），表明〓团簇较其它更稳定，从而得到了与飞行时间质谱实验结果相一致的结论。

The results indicated that:(1) It is viable to use the electron affinity energy of the metal atom in the catalyst, and the ortho-/para-substition ratio of phenolic model compounds as parameters. Thereby, the related data of Resole resins catalyzed by different catalysts can be put into the same training set for modelling.

研究结果表明：（1）用催化剂中金属原子的电子亲合能和酚醛模型化合物的邻／对位取代比作为特征参数是可行的，因而可将不同类型催化剂催化的Resole树脂的有关数据合并于同一训练集中进行建模。

It was found:(1) the stability of the clusters increased with the bond number in the clusters;(2) the clusters with three dimensional geometry are more stable than ones with two decisional geometry;(3) the ionic potential of the clusters in gas phase and on the surface of the silver bromide grains are all positive, and the electron affinity are all negative.

结果表明；气相中团簇的稳定性随团簇中键数的增加而升高，三维构型的稳定性大于二维构型的稳定性；气相中Ag〓团簇的电离能都大于零，电子亲和势都小于零；溴化银颗粒表面的Ag〓团簇的电离势也是大于零，电子亲和势也是小于零。

A series of technologies were established and applied to this study, which include MR electron microscopy by using mannosylated albumin-colloidal gold (DMA-G10) as probe, modified CBB method for acrosome reaction detecting, improved model of human acrosome reaction induced by mZPS (solubilized mouse zona pellucida), in vitro heterogenic fertilization and affinity cytochemistry, preparation and purification of proteins.

本研究建立了MR的电子显微镜探针——甘露糖基化白蛋白-胶体金及其检测法、移植建立了人精子顶体反应的CBB检测法、改良了mZPS诱导人精子顶体反应实验模型，同时运用体外获能、异种体外受精、亲和细胞化学、蛋白质提纯制备等技术与实验模型，对人精子MR的表达、定位和生理功能加以探讨。

Thirdly, electronic properties, such as HOMO and LUMO energies, band gaps, the ionization potential and electron affinity of 2, 7-linked and 3, 6-linked carbazole trimers, two conjugated oligomers with different linkage of carbazole, were studied by the density functional theory with Becke–Lee–Young–Parr composite exchange correlation functional (B3LYP).

第三，采用密度泛函理论在6-31G*基组上分别优化了两种2，7-和3，6-咔唑三聚物的电子结构，如HOMO和LUMO能级，能隙，电离能和电子亲和势。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
