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。

When there is plenty of rope available, the following method illustrated in Figure 20-3 is most secure. The best river man goes first belayed by the second best who goes last. When A gets across, he moves upstream and sets upa belay opposite B. and the next wader ties in at B. Then C pendulums across taking about the same path as A. while B lets rope out, and A keeps the rope taut. If C falls, he should be pendulumed to the most favorable bank (hopefully to A so that the crossing is accomplished).

The action of page headline is self-evident, the rank that searching engine gave caption very great weight in the mechanism, look in me a successful caption should have these a few kinds of features: A, true the clou that mirrorred page article, caption and content write a law abhorrently is wrong apparently, it can let you lose the faith that searchs engine, also can let more caller prediction of a person's luck in a given year drop likewise. On the B, foundation in A, beautiful idea designs a more absorbing caption, a headline that contains window often searchs the webpage before the result to have taller hit in you than the platoon, as this hit rise, your rank also can be alled alone by search engine place takes seriously slowly, this kind of phenomenon once was in the article of President SEO (the imitate of the soft costal region of Baidu and Baidu place ignore is searched) in had mentioned. C, reasonable keyword density, avoid by all means does not pile up again in caption keyword, this kind of method already too pediatric.

页面标题的作用不言而喻，在搜索引擎的排名机制中给予了标题很大的权重，在我看来一个成功的标题应该具有这几种特征：A、真实反映了页面文章的中心思想，标题和内容不一致的写法显然是错误的，它会让你失去搜索引擎的信任，同样也会让更多的访客流失掉。B、在A的基础上，花心思设计一个更加吸引人的标题，一个含有亮点的标题往往比排在你搜索结果前面的网页有更高的点击率，随着这个点击率的提高，你的排名也会慢慢被搜索引擎所重视，这种现象曾经在SEO校长的文章(百度的软肋与百度所漠视的模拟搜索)中提到过。C、合理的关键词密度，切忌在标题中不要再堆积关键词了，这种手段已经太小儿科了。

Floral organ determination is best explained by the ABCDE model postulated by genetic studies of Arabidopsis thaliana. Sepals are determined by A and E class genes; petals are determined by A, B, and E; stamens by B, C, and E; and carpels by C and E class genes. A, B, C, and E class gene lineages are known having duplicated several times during the evolution of angiosperms. One of the noted major duplication events occurred in the origin of the early angiosperms, leading to the formation of subgroups of B/C/D/E class. Another one occurred near the basal eudicots and gave rise to further subgroups in A/B/C/D/E class genes among core eudicots. The phylogenetic position of the family Buxaceae is located right where the second major duplication of ABCDE genes might have occurred, which is supported by multiple gene (nuclear 18S rDNA, chloroplast rbcL and atpB) phylogenetic analyses.

目前经由模式植物阿伯芥的研究，建花部器官决定基因的调控，即花萼由A、E 群基因共同决定，花瓣由A、B、E 群基因，雄蕊由B、C、E 群基因，而心皮由C 和E 群基因决定。A、B、C、E 四群基因在被子植物的演化过程中发生过次的复制事件，其中比较重要的一次发生在早期被子植物演化出之时，形成B/C/D/E 群基因的次系群；另一次复制事件则发生在真双子植物基群附近，形成仅於核心真双子植物的A/B/C/D/E 群基因之次系群。
