In the first part, it was investigated the interaction between Pb2+ and La4Ti9O24 ceramic bulk. The result shows that a significant Pb2+ diffusion into La4Ti9O24 ceramic bulk and a significant crystallization of the La2/3TiO3-type phase is clearly observed in the Pb2+ diffusion layer. The reacted zone consists of the La2/3TiO3-type phase exhibits the linear dependence of the square of the thickness, x, on the heat-treated time, t, in excellent agreement with the parabolic law x2 = kt, where k is the growth rate coefficient. The kinetic study thus indicates that the Pb2+/La4Ti9O24 interaction strictly obeys the theory of the reactive diffusion. Furthermore, the experimental k values were used to determine the associated activation energy, Ea, for the formation of La2/3TiO3-type phase using the Arrhenius plot and the following least-square equation, ln =-Ea/RT + A, where T is the annealing temperature, R is the universal gas constant, and A is a constant, resulting in Ea ~ 607 ?b 60 kJ/mol.

首先， 以巨观的方式观察PbO与La4Ti9O24陶瓷体介面的反应现象；利用X-ray绕射分析以及扫描式电子显微镜来观察不同的热处理温度以及不同的持温时间所制作的样品，研究结果发现， Pb2+离子会渗入到La4Ti9O24陶瓷内，同时在Pb2+离子所渗入的区域内会产生新的La2/3TiO3-type钙钛矿斜方晶相；藉由量测不同温度与时间之样品，其因Pb2+离子渗入而产生之La2/3TiO3-type相层厚度之关系，符合反应式扩散机制中 x2 = kt 之关系式(其中 x：扩散层厚度； k：反应速率常数； t：反应时间)；进一步将不同实验条件所得到之反应速率常数值代入Arrhenius方程式ln (k =-Ea/RT + A ，其中Ea：活化能； T：绝对温度； R：气体反应常数； A：常数，可以求得Pb2+离子与La4Ti9O24陶瓷发生反应式扩散所需之活化能为607 ± 60 kJ/mol。

研究结果显示：多媒体影音光碟介入前后研究对象医疗决策比较，实验组前测对后测呈显著差异(t=2.30， p=。00)，对照组前测对后测未呈显著差异(t=1.32， p=。53)。

For compounds 4Ⅰ and 4Ⅱ, both melting point T and isotropization temperature T were decreased with the increase of the carbon numbers of the end alkoxy groups.

随分子末端烷氧基碳原子数增加，化合物4Ⅰ和4Ⅱ的熔点T(下标 m和液晶态的清亮点T(下标 i逐渐降低，液晶态温度范围较宽。

Methods: Anergic T cell was induced by combination of B7-1 mAb and cyclosporin A in vitro, cytokine gene of anergic T cells was detected by RT-PCR.

将B7-1单抗和CsA联用在体外诱致了抗原特异性T细胞无能，采用RT-PCR法检测了无能T细胞细胞因子基因的表达。

This may be accomplished by using a gasketed 'T' fitting or by a short length of sewer pipe that has a gasketed belled end, and then connecting it to a solvent weld 'T' fitting.

使用一个带衬垫的&T&形装置或短的带衬垫承插端的污水管，然后将它接在一个溶剂粘接的&T&型装置上。

The tree T=is a bichromatic tree subgraph in a maximal plannar graph G, in which the subgraph induced by V_t is a tree and T is a component of some bichromatic subgraph Gij of some 4-coloring of G.

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.
