The coordination mode of La can be described as a distorted aquare antiprism, which was completed by two oxygen atoms from one oxalate, four oxygen atoms from four different PDC ligands, and two oxygen atoms from two water molecules.

La呈现四方反棱柱体的配位模式，分别和2个来自同一个草酸配体的氧原子、4个来自4个PDC配体的氧原子以及2个来自2个配位水分子的氧原子配位。

The neighbor-ing two Gd3+ ions are connected by two simple bridged carboxyl groups and a μ2-bridging carboxylgroup. Each G-d3+ ion is simuetaneosly coordinated by two water molecules. So the coordination num-ber of Gd3+ is nine, forming a coordination polyhedron of distorted mono capped square antiprism.

相邻Gd3+离子通过2个简单羧基桥和1个μ2羧基桥联结起来，还有2个水分子配位于每个Gd3+离子，所以Gd3+的配位数为9，形成变形的单帽四方反棱柱体。

Motheds: to select 336 lomars with pulposis or apicitis from the aged and to devide them into two groups. in group the control group,the illed teeth were given only the root canal therapy. in group the experimental group, according to the difference of every root canal, the unobstructed root canals were treated by root canal therapy. while the obstructed ones were given the root canal resinifying, use two kinds of therapy method together to molais' pathological changes.then their curative effects were observed after two year.

选取336例中老年人患有不可复性牙髓炎、牙髓坏死、牙髓钙化、牙内吸收和急、慢性根尖周炎的患牙358颗，随机分为对照组和实验组，对对照组行常规根管治疗，对实验组则根据每个牙齿各根管的不同情况，采用根管-塑化联合治疗，观察2年进行临床评价。

Next the discussion in this study, about an ellipse with an angle of attack and two circular cylinders with different diameters in the flow, the aim of this study is investigated for the ability of the present numerical method by solving the suppression of the vortex shedding flow behind the two-cylinder system which was kind of difficult to reach by a Cartesian grid method. In this study, the suppression of the vortex shedding flow is tested to solve a uniform flow past through two different diameter cylindrical in the flow field with Fractional Step Method and Immersed Boundary Method.The numerical method which we investigated is showed that the results of the problem is appropriable in other literatures.

接著探讨流过具攻角之椭圆柱体流场及流过圆柱抑制涡漩逸出之流场，目的是要研究利用控制圆柱来抑制下游涡流的流场行为，本文采用分步法配合内嵌边界法数值解析一均匀流流经两不同直径的圆柱流场，来测试抑制涡流逸出的问题，根据现有的数值结果发现试验运用了合适的方法且得到令人满意的结果。

The ISSR markers were fitted to a 3:1 ratio of simplex and duplex segregation for the parental alleles, as the sweet potato was expected to be autohexaploid. Fourteen and nine quantitative trait loci linked to specific ISSR markers were detected for traits in (NH×TN27) and (TN27×NH), respectively. Twenty-two of these QTL-mapped markers were unique to the specific traits, and two were linked to two traits in each linkage map. These markers appear to be applicable to crop improvement.

ISSR标识因子符合六倍体亲本对偶基因simplex与duplex的3：1分离比。14与9个与专一性ISSR标识因子连锁之数量性状基因座，分别检测NH×TN27与TN27×NH之性状，其中22个数量性状基因座图绘之标志因子，对於特殊性状而言具有特殊性；每个连锁图谱中，有两个QTL图绘之标志因子与两个性状连锁，这些标志因子应可应用於作物改良。

The experimental results from cyclic voltammetry and constant-potential electrolysis show that the mechanism of the reaction was two molecules and three steps electrochemical process with eight-electrons transferred: anion radical arose in the first step; two-electrons were transferred in the second step and accompanied with coupling reaction of radicals and protonation and dehydrate, the main product was azoxybenzene; two-electrons were transferred in the third step, and azobenzene was achieved.

研究结果表明，硝基苯在铂电极上的电还原反应为双分子八电子三步骤电化学过程：第一步反应为准可逆单电子转移步骤，产生阴离子自由基；第二步为二电子转移步骤，并伴有随后的双分子不可逆自由基偶合反应和快速质子化及脱水反应，主要产物为氧化偶氮苯；第三步是二电子转移产生偶氮苯的过程。

Through comparing Luis Barragan and Charles Correa,two architects from developing countries with similar regional characteristics,the author discusses two different ways of romance and reality,in order to analyze the two architects pursuit of different values.

通过对路易斯·巴拉干和查尔斯。柯里亚两位来自具有相似地域特点的发展中国家的建筑师的比较，来探讨浪漫与现实这两条截然不同的道路，从而剖析两位建筑师不同的价值追求。

And why it is that writers write but fingers don't fing,grocers don't groce and hammers don't ham If the plural of tooth is teeth,why isn't the plural of booth beeth If you have one goose,two geese,why not one moose,two meese,or one index,two indices

如果牙齿的复数是teeth，那为什么售货亭的复数不是beeth？一只鹅我们用goose，两只鹅用geese，那么，一只驼鹿用moose，两只驼鹿就应该是meese了？为什么一条索引是index，两条索引却成了indices？
