Degree sum conditions of IM-extendable graphs are researched. The main results are as follows:(1) Let G be a graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,, then G is IM-extendable.(2) Let G be a claw-free graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,d+d≥2n+3, then G is IM-extendable.

研究导出匹配可扩图的度和条件，主要结果如下：(1)若图G有2n个顶点，且对于G中每一对不相邻的顶点u和v，，则G是导出匹配可扩的；(2)若G是一个有2n个顶点的无爪图，且对于G中每一对不相邻的顶点u和v，d+d≥2n+3，则G是导出匹配可扩的。

The nucleotide sequences of the PAP gene and PAPⅡ gene in the root of Phytolacca americana were determined by reverse transcription polymerase chain reaction and PCR. The gene comprises 942bp and 933bp respectively, encoding 313 amino acids and 310 amino acids. When PAP gene and PAPⅡ gene sequences in the root were compared with those in the spring leaves and summer ones, the highest similarity 100% and 99. 8% were observed respectively. They both had one open reading frame . Analysis of the two sequences showed, in fact, they belonged to one species.

以美洲商陆根为材料，提取其总RNA、反转录，用一对PAP基因的特异性引物和一对PAPⅡ的特异性引物，分别对反转录产物进行PCR扩增，将扩增的目的片段进行序列分析，结果扩增出来的PAP基因与已经报道的序列完全相同，扩增出来的PAPⅡ基因与已经报道的序列同源性也在99.8％，而且它们都各自编码一个开放阅读框架，可以说美洲商陆根中肯定存在PAP和PAPⅡ基因，并已经转录。

But on the way, Perdy also chases Pongo, in the process also dragging poor Anita into the lake. The result of all these mishaps is that Roger and Anita quickly fall in love, and in no time both dogs and owners have united in marriage, and are living a happy life together.

在回家的路上，Perdy 又去追 Pongo ， Anita 也被拖进了河堙C这样偶然的机缘，使两个人情投意合，闪电般地，一对新人和一对新犬双双步入教堂，开始了他们甜美的生活。

The bread maker also includes tray holder members to be combined with opposite ends of a pair of tray members; a pair of guides mounted on inner sidewalls of the oven compartment facing each other to slidably guide the tray holder members by being slidingly combined with the tray holder members; and a shock absorber between the tray holder member and the guide.

面包机还包括与一对盘件的相对端部结合的盘保持件；安装在烤箱室内侧壁上的一对引导件，所述引导件彼此面对以通过与盘保持件的滑动结合而可滑动地引导盘保持件；以及介于盘保持件与引导件之间的震动吸收器。

Now that you've made these lists, make a couple of copies and hang one on your workbench, one on your desk, etc. to look at and think about for a few weeks.

你现在所做的这些名单，使一对夫妇的副本和坑一对您的工作台，一个在您的书桌上，等看待和思考了数周。

One belonged to him and the other to the LORD.

一对是他的，一对是上帝的。

But when the war jobs had taken those families away, someof the houses had been carted elsewhere to serve as garages or chicken sheds. A couple of those that wereleft were empty, and the rest were mostly occupied by old people: the old bachelor blacksmith; thecouple who used to have a grocery store and still had an Orange Crush sign in their front window;another couple who bootlegged and buried their money, it was said, in quart sealers in the back yard; andthe old women who had been left on their own. Mrs. Currie raised dogs that raced about barking insanelyall day in a wire pen and at night were taken inside her house, which was partly built into the bank of ahill and must have been very dark and smelly.

但是当战事将那些家庭带走以后，一些房子被载到别处作车库或鸡棚了，留下的都空着，其馀的也大多住着老人：一个老单身汉；一个老铁匠；还有一对以前开食品杂货店的夫妇，他们的前窗上现在还贴着榨橘汁的标志；一对非法制酒的夫妇据说把钱藏在一个一夸脱的密封容器里埋在后院里。

Based on this requirement, this paper introduced steerable filters: generated a pair of even and odd filtered images by convoluting a quadrature pair of steerable filters with a source image, and then through continuously varying their phases over time, it gave the vision of an object in motion without changing its position. created the animation conveniently in this way.

基于这种需求，将定向滤波引入到非真实感动画中：利用一对正交的定向滤波核与源图像进行卷积运算，产生一对奇偶滤波图像，并通过不断改变其相位得到一系列运动的图像，使图像内的物体在实际位置并不发生改变的情况下，产生视觉上的动画效果，从而方便地生成非真实感动画。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
