1 Steel plant,and profound analysis was carried out for the capability of reducing impurity of blowing-argon,ladle reefing,middle-vessel,crystallizer,and the infection of variant deoxidation ability on the content,composition and shape of the impurity in carting blank,through gas-analysis,image-analysis and electron microscope scan.

为了解济钢一炼钢钢水纯净度的实际状况，选择两个典型钢种BC和AH32为分析对象，通过气体分析、图像分析和电子显微镜扫描分析分别对吹氩处理和LF炉精炼处理、中间包和结晶器去除夹杂物的能力及采用不同的脱氧工艺对铸坯夹杂物含量、组成及形态的影响进行了深入分析，找出了全氧和氮的变化规律、夹杂物粒度分布及主要组成，为研究如何降低夹杂物含量和改变夹杂物形态提供了技术基础。

It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。

The results show that this reaction proceeds in two step: 1 silylene and formaldehyde form an intermediate complex, which is a kind of exothermal reaction with no barrier; 2 the intermediate complex isomerizes to sive the product. The barrier for the second step is 51.4kJ·mol^-^1 at MP2/6-31G^*//6-31G^* level (with zero-point energies correction). In view of dynamics and thermodynamics, it is between 300～400K that the reaction will have not only larger spontaneous tendency and equilibrium constant but also quicker reaction rate.

结果表明，此反应历程由两步组成：1硅烯与甲醛生成一中间配合物，是一无势垒的放热反应，2中间配合物异构化为产物，此步势垒经零点能校正后只有51.4kJ·mol^-^1(MP2/6-31G^*//6-31G^*)；从热力学和动力学的综合角度考虑，该反应在300～400K温度下进行为宜，如此，反应既有较大的自发趋势和平衡常数，又具有较快的反应速率。

All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

通过研究配合物的单晶结构，我们发现叔丁基取代的不对称N_2O_2配体与ZrCl_4反应生成的锆配合物为氧桥和羟基桥连接的双核锆配合物，中间过程涉及单核锆配合物中氯原子部分水解，并得到氯原子部分水解的双核锆配合物和全部水(来源：8e6eAB67C论文网www.abclunwen.com)解的四核锆配合物的晶体结构，在晶体培养过程中发现双核锆配合物能够以手性自发拆分结晶析出。

Surface aluminates a re formed on the surface of the catalysts and the presence of Ni favorites the f ormation of surface aluminates.

Ni的存在会影响表面重构过程从而影响催化剂的活性和选择性，在所研究的含Ni催化剂上，CO2加氢反应经历了生成双齿表面吸附中间物的过程。

In the case of Li, the γ-peak (nitrate and nitrite species on surface) of NO desorption increases, the intermediate N〓O desorbs at higher temperature. In the case of Ce, the α-peak (species on the 〓 acidic sites) of NO desorption decreases, and N〓O desorbs at lower temperature.

对NO吸附在催化剂表面的TPD谱进行了分析，观察到催化剂中加入Li或Ce助剂后，NO的脱附峰面积，脱附峰形状都有明显的变化，Li的加入使NO脱附的γ峰(表面硝酸盐亚硝酸盐物种)明显增加，中间物N〓O脱附温度增高；Ce的加入使NO脱附的α峰减小，而N〓O的脱附温度降低。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。
