In the fourth chapter, we shall determine the adjacent vertex distinguishing incidence chromatic number of complete bipartite graphs, C_m,·F_n graphs and one type ofθ- graph.

在第四章中我们将确定完全二部图、C_m·F_n图及一类θ-图的邻点可区别关联色数。

It was found that this kind of porphyrin complexes could be effectively separated only with the mobile phase containing amine together with organic acid.

探讨了不同分离参数对它们色谱保留行为的影响发现：流动相中存在有机酸和胺类添加剂才能使四个稀土卟啉配合物有效分离。

The Athenian author Xenophon (ca.430-ca.355) informs us about it in book four of his Anabasis .

雅典作者色诺芬（ ca.430 - ca.355 ）告诉我们这本书在他的四个假。

Purification and analysis of AT-toxin Firstly, we detected the components of protein and nonprotein, the results showed that AT-toxin is a nonprotein. We have carried out the liquid chromatogram analysis of the toxin. The result indicates that there are many components in this toxin and there are four kinds of components which content is more than others. At last, we have the experiment of separating the cpmpositions with the silica gel and we get four components which are active.

AT-毒素的初步纯化与分析为确定AT-毒素的组分，首先对毒素的蛋白质和非蛋白质组分的毒性进行了测定，结果表明：AT-毒素活性组分为非蛋白质；对毒素进行硅胶G薄层层析，初步分离得到10种组分，其中四种组分具有活性：组分Ⅵ、Ⅶ、Ⅷ、Ⅸ，初步说明了该毒素含有多种组分；进一步对该毒素进行液相色谱分析，也发现该毒素含多种组分，其中四种组分峰高和峰面积较大，含量较高；其致毒活性可能是由这些组分协同作用的结果，它们之间可能存在正协同或负协同作用关系。

Later, a British ambassador to North Korea with diplomats from the Western aesthetic point of view of this flag-Tai Chi nosy made changes and removed the titillation of four downs, and the remaining four downs oblique symmetric stretching, the entire rectangular flag design submissions, yin and yang fish patterns into two colors red and blue, so now we can see eunuchs Korean flag.

后来，一名英国驻朝鲜的使节用西方美学的角度为这面太极八卦旗做了修改，去掉了八卦中的四卦，把剩下的四卦斜向对称拉伸，使整个国旗图案呈长方形，把阴阳鱼图案改为红蓝两色，这样才有了现在我们看到的韩国太监旗。

Tgs are about 573 K for copolyimides based on pyromellitic dianhydride and 533—543 K for those based on 3,3′,4,4′-diphenylethertetra-carboxylic dianhydride and are almost independent of the chromophore loading level.

以刚性相对较大的均苯四甲酸二酐为二酐单体的PPI 的Tg在573 K左右；以二苯醚-3，3′，4，4′-四甲酸二酐为单体的OPI 的Tg在533～543 K之间，且基本与染料发色团含量无关。

During this years, TCM has a prominent effect on Dysfunctional Dyspepsia,so we study the effect of SiNiSan of soup on the Dysfunctional Dyspepsia sharply from the ability of stomach emptying and the ability of intestines pussing on the normal Kunming rats by the coloring matter,and the chang of the nerve fiber, nerve qualitative, on the stomach organize of normal SD ratsMethods:In the experiment, the thirty Kunming rats, whose avoirdupois are about twenty grammes,and thirty S. D rats, whose avoirdupois are about two hundred grammes,were randomly divided into three groups, 0. 9yS group, SiNiSan of soup group and Mosapride Citrate group.

本课题通过对正常小鼠胃内葡聚糖蓝-2000残留量、小肠内葡聚糖蓝-2000推进率，来研究四逆散对小鼠胃排空、小肠推进的影响；通过采用正常大鼠肠道气囊法，记录正常大鼠用药后肠收缩幅度和频率的变化；采用医学彩色图象全自动分析系统，分析用药后正常大鼠胃窦组织中NOS阳性神经元分布面积和酶活性的变化；采用硝酸酶还原法和比色法，检测用药后正常大鼠胃窦组织中NO和TchE的含量变化，通过以上几个方面，研究四逆散的促胃肠动力作用及其作用机制。

He merle gene is very common, and very popular, in the Australian Shepherd breed (they are sometimes called "those little blue dogs");,it is relatively common among Collies and Shelties as well.

产生双merle的唯一途径就是二只陨石繁殖。其结果，统计学上四分之一的宝宝为正常色，二分之一为携带单merle的陨石，另四分之一就是双merle基因的宝宝。

产生双merle的唯一途径就是二只陨石繁殖。其结果，统计学上四分之一的宝宝为正常色，二分之一为携带单merle的陨石，另四分之一就是双merle基因的宝宝。澳牧中merle基因就广泛地存在，在边境和小喜也较常见。

Determination of Tyrosine in Urine Spectrophotometric Method;2. For chemical pre-extraction, MSTFA/TMSL derivatization reaction, GC/MS analysis, it is confirmed that two main metabolites (19-no-randrosterone and 19-noretiocholanolone) were found in nandrolone urine.

本文对合成的19-去甲雄烷醇酮的四个差向异构体混合物进行气相色谱分离，对诺龙和炔诺酮用药后，留取的人尿样通过化学预处理，MSTFA/TMSI衍生化反应，GC/MS分析，确证了尿样中诺龙的两个主要代谢产物为19-去甲雄酮和19-去甲原胆烷醇酮，炔诺酮的两个主要代谢物是四氢炔诺酮的两个形式，可能是3α-OH-5α-THINE和3α-OH-5β-THINE，在炔诺酮代谢前期，还发现有诺龙的上述两个代谢物存在。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
