The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

The result shows that the blend membranes have good mechanical properties and can conquer the weakness of silk membranes,stiffness and brickleness.

采用共混法制备丝素-壳聚糖共混膜，并测定其力学性能，结果表明各种配比的丝素-壳聚糖共混膜均具有良好的机械性能，能够克服纯丝素膜刚而脆的弱点。

Silk fibroin-chitosan blend membranes were prepared by mixing method and the mechanics of blend membranes was measured. The result shows that the blend membranes have good mechanical properties and can conquer the weakness of silk membranes, stiffness and brickleness.

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。

Definition: This is an altruistic role in the confrontation of games. Compital refers to the focus on evidence, while disregarding logic, which has no principles but simple rules; in other words, it denotes a part of obligatory supply. I name this phenomenon in games the games compital.

博弈共产： Games Compital 它是博弈对局中的一个利他角色，共产是指只注重证据而不考虑逻辑，没有原理而只有简单的规则，也就是说它包含有一部分义务性的提供，我把博弈中的这种现象叫做博弈共产。

Therefore it is licit to concelebrate with Bishops and with priests who are in communion with the Pope, even if they are recognized by the civil authorities and maintain a relationship with entities desired by the State and extraneous to the structure of the Church, provided as was said earlier cf.

因此，和与教宗共融的主教及司铎共祭是合法的，即使他们是政府认可或是与国家建立的、与教会的架构无关的机构保持关系，如上面已说过(参见第7号第8段)─只要这种认可和关系没有违背不可背弃的信仰和教会共融的原则。

In Chapter 2,we introduce the definition of adding machines,and give sev-eral equivalent conditions on the existence of several kinds of conjugacy and semi-conjugacy relations between adding machines.

第二章介绍了广义符号空间上的加法机器的定义，给出了加法机器之间存在着各种共轭及半共轭关系的多个充要条件，证明了加法机器之间的拓扑半共轭一定是一个群同态与一个平移映射的复合，并研究了此同态的核的构成。

Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

化学位移值表示的诱导效应参数表明甲基具有吸电子诱导效应，经校正后的化学位移值表示的共轭效应参数表明甲基具有微弱的给电子共轭效应，甚至其共轭效应有可能正处于给电子和吸电子的临界状态，总之相对于氢原子，甲基具有吸电子效应。
