Little overdose aluminum caused that the displacement reaction occurred between Al and TiO2 with releasing much heat, and Al2O3 and free Ti were formed, then the active Ti combined with C and produced TiC; more overdose aluminum caused the thermit reaction happened between Al and TiO2, and was generated, then Al3 Ti combined with C and produced TiC.

首先在无过量铝的情况下，Al与TiO2发生置换反应，生成了Ai2O3和游离态，而后游离态与C结合生成TiC；而存在过量铝的情况下，首先发生铝热反应生成Al3Ti，进而Al3Ti与C结合生成TiC。最终完全获得Ai2O3-TiC/Al复合材料。

With a nitrogen purge after treatment at 300℃ the nanotubed titanic acid could not be suit as stationary phase for analysis of hydrocarbons C〓～C〓.

在300℃和N〓气氛下处理以后，纳米管特性完全消失，其不适宜再作为分析C〓～C〓烷烃的固定相。

Phenyl or m -tolyl selenoamides reacted with functionalized α-haloacetic acid in 1∶1 or 1∶2 molar ratio with no catalyst in various alcohols to undergo a selenium transfer reaction. This reaction in dif-ferent molar ratios furnished the same C—Se—Se—C coupling products with a special structure bis diselenide. A new and facile method for synthesis of such bis(alkoxycarbonyl-methyl) diselenides with the advantages of mild reaction conditions, high yields, easy availability of starting materials and good chemical selectivity was provided.

芳基硒代酰胺与氯乙酸在各种醇中无催化剂下以1∶1和1∶2的比例投入，发生硒转移反应，不同原料投入比下的反应生成了同一种C—Se—Se—C偶联产物——具有多功能团的二烷氧羰基甲基二硒醚，提供了一种新的合成二烷氧羰基甲基二硒醚的简便方法，且反应具有条件温和、产率高、原料易得和选择性好等优点。

In fruits and vegetables, tomatoes are the highest content of vitamin C a, so to ensure a tomato a day can meet the daily requirement of vitamin C.

在水果和蔬菜中，西红柿是维生素C含量最高的一种，所以每天至少保证一个西红柿，可以满足一天所需的维生素C。

Thus in the tonic triad of C major in root position, C-E-G, the middle note may be placed one or more octaves higher without affecting the nature of the triad.

在本为和弦C大调主音三和弦中，C-E-G，中间音可被一个或多个高于八度的音替换，而不影响三和弦的性质。

For example the first inversion of the tonic triad of C major may be sounded with the middle note an octave higher, giving E - C - G, with G forming a compound third with the bass E.

例如，C大调主音三和弦的第一转位与中间音发出高于八度的音，E - C – G，G和低音E构成复三度。

A computational result of RHF/LANL2DZ optimized structure and total energy shows that the isomers with C H…π structure have lower total energy, and that stability and isomeric preference of isomer are related to the C H…π interaction in the isomer.

用 RHF/LANL2DZ对该体系可能的异构体进行结构、能量优化，可能形成C—H…π相互作用的异构体具有较好的稳定性。C—H…π相互作用对含吡啶环的[CoN5Cl]^2+系配合物的异构体的选择性形成及其稳定性具有重要作用。

The affiliation relation is transitive: if A and B are affiliated and B and C are affiliated then we take A and C to be affiliated even if there is no direct evidence of the fact.

从属关系是具有传递性的：如果A和B有从属关系并且B和C也有从属关系，那么即使A和C没有明显的直接联系，我们也会认为它们有从属关系。

In a transitive relationship, the relationship from A to B and A to C is the same as that of B to C.

在可传递性关系中，从A至B和从A至C的关系与从B至C的关系相同。

SiO〓 crystal transformation was improved by adding Na〓SO〓, alpha cristobalite but not tridymite was catalytic active support. C〓 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO〓. W-O in catalyst surface was not active species. The support combined with S, W, P show low activity and high C〓 selectivity.

Na〓SO〓的加入促进了SiO〓晶型的转化，α-方石英是催化活性载体成分，而鳞石英没有甲烷氧化偶联反应活性。W和P的加入改善了C〓烃的选择性，抑制了SiO〓的深度氧化特性；W-O物种不是催化活性物种；由S、W、P及SiO〓组成的载体反应活性较差，但选择性较好；同时S元素对C〓烃的选择性的贡献有限。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
