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？

In the 2A1 distorted trigonal bipyramid structure ,the single non equivalent Ga atom has the population of 4s 4p ,while the two equivalent Ga atoms have the population of 4s 4p .this compares with a Ga population of 4s 4p in the undistorted D3h structure ,hence the jahn-teller distortion causes depletion of the charge density on the 4s orbital of the non-equivalent Ga atom, and enhancement of charge density on the 4s orbital for the two equivalent atoms .an opposite trend is observed for the 4p orbitals of these Ga atoms .the P population for the two equivalent atoms is 3s 3p .the populations of the other 2B1 state with the edge-capped tetrahedral structure are similar with the exception that all three Ga atoms have similar but not identical populations .

在2A1被变形的三角bipyramid结构，唯一非等效Ga原子有4s 4p的人口，而二个等效Ga原子在未变形的D3h结构有4s 4p 。this的人口和4s相比4p的Ga人口，因此jahn出纳畸变在non-equivalent Ga原子的4s轨道导致电荷密度的取尽，并且电荷密度的改进在4s轨道为二个等效原子。an在趋向对面对这些Ga原子4p轨道被观察。the人口为二个等效原子是另一个2B1状态3s 3p 。the人口与边缘加盖的四面体结构是相似的P 除之外全部三个Ga原子有相似，但不相同人口。

In this paper, an important pest of cruciferous vegetables xylostella and its two dominant species in the parasitic wasp - Cotesia plutellae bee, Diadegma semi-closed two parasitic system studied two parasitic wasps of Nutritional regulation of the host Plutella xylostella, from parasitic to parasitic found after the fifth day, five days, all groups the body weight of diamondback moth larvae are showing an increasing trend, not parasitic larvae of the diamondback moth has been higher than was body weight parasitic larvae of Plutella xylostella, and was Ichneumonidae parasitic larvae of the diamondback moth important than being clear Braconidae parasitic weight of the diamondback moth larvae.

本文以重要的十字花科蔬菜害虫小菜蛾及其两种优势种内寄生蜂——菜蛾盘绒茧蜂、半闭弯尾姬蜂两个寄生体系为研究对象，研究了两种寄生蜂对寄主小菜蛾营养的调控，发现从寄生至寄生后的第五天，五天时间内，所有组小菜蛾幼虫的体重均是呈现增加的趋势，未被寄生的小菜蛾幼虫体重一直保持大于被寄生小菜蛾幼虫，而且被姬蜂寄生的小菜蛾幼虫体重要明显的大于被茧蜂寄生的小菜蛾幼虫体重。

The intergeneric phylogenetic trees of water lilies showed that Nelumbo and Ceratophyllum form a sister group, but with relatively high sequence divergence, supporting that place the two genera into two distinct families; and Brasenia and Cabomba form a sister group, with relatively low sequence divergence, supporting that the two genera were placed the same family Cabombaceae.

结果表明：莲属与金鱼藻属构成姐妹群，但序列分歧度较大，支持将两个属独立成科的观点；莼菜属与水盾草属构成姐妹群，且序列分歧度较小，支持现有的莼菜科处理。

Using two kinds of representative bridgeless PFC topologies as main circuit and IR1150 as control chip, two bridgeless PFC prototypes have been designed and the EMI of the two circuits has been tested.
