The results point out that the values of kinetic parameters are altered with the addition of Ti and C, which change the crystallization type from difficult nucleation and easy growth pattern to easy nucleation and difficult growth pattern, and this difficult nucleation and easy growth pattern may be the main reason why fine and even microstructure is gained in Ti and C doped alloys.The influences of Nd content, B content, partial substitution of Nd by Pr on the microstructure and magnetic properties have also been researched.

文章从动力学理论的观点揭示了合金显微结构与合金晶化动力学特性之间的关系，指出Ti和C添加改变了Nd9.4Fe79.6B11合金晶相析出时的动力学参量值，使合金晶化时晶相的析出方式由难形核易长大型加热管转变为易形核难长大型，这种易形核而难长大的晶化动力学特征，是Ti和C添加合金获得细小均匀的纳米晶结构的根本原因。

The influence of Ti on microstructural and magnetic properties of the FePt films was investigated in detail. X-ray diffraction patterns indicate that the films deposited onto glass substrates with the addition of Ti layer form a ternary FePtTi alloy possessing L10 texture.

详细研究了Ti衬底层对FePt颗粒膜的微结构和磁特性的影响。X射线衍射图谱表明样品形成了较有序的L10织构，Ti和FePt形成了三元FePtTi合金。

It was found that the tetrahedrally coordinated Ti in the titanosilicate molecular sieve was the main reason to arise H2O2 decomposition as well as the effect of acid centers of the catalyst.

结果表明，分子筛骨架Ti和其拥有的酸性位是造成H2O2在分子筛上分解的主要原因，非骨架Ti对H2O2分解的影响弱于骨架Ti.H2O2的无效分解直接影响反应物的转化效率。

结果表明：在Ti-6Al-1.8C中主要存在Ti和TiC两种相。

It is found that the indirect electroreduction of maleic acid to butane diacid was achieved by Ti~/Ti~ redox system on the nanocrystalline TiO2 film surface, the electrode reaction mechanism is the called catalytic mechanism.

其中TiO_2/Ti_2O_3电对对马来酸具有异相电催化还原活性，纳米TiO_2膜中的Ti~/Ti~氧化还原电对作为媒质间接电还原马来酸为丁二酸，反应机理为电化学偶联随后化学催化反应机理。

Using pure Ti and Ni powders, a promising artificial bone material, nearly equiatomic stoichiometry Ti-Ni shape memory alloys porosity was prepared by combustion synthesis method.

It is worth mentioning that the Fe-Ti-C system of 75wt% Fe content belongs to low exothermal system, the combustion synthesis reaction took place at 734'C under the preset heating rate 1000℃/s based on the electric field, and there were small TiC particles without Fe〓Ti in the products, which also was one of the novelties of this research.

值得一提的是，对于Fe含量高达75wt％的Fe-Ti-C体系实际上属于低放热体系，然而在电场诱导下，当预设升温速度提高至1000℃/s，在743℃时发生了燃烧合成反应，所获的合成产物中TiC颗粒细小，且没有Fe〓Ti相出现。

The results show that the microstructure of as-cast Ti-45Al-7Nb-0·15B-0·4W becomes fineafter being HIPped and heat treated, and a more perfect lamellar microstructure is got. The temperature ofαphase

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
