文章讨论了两类广义条件数的几种表达式，研究了这两类广义条件数之间的关系，并将它们用到算子方程的扰动估计中，推广了Demko[IV.1]中的结果。

We determined the mitochondrial DNA sequence of S. yangtsekiense and discussed the phylogenetic status of freshwater crabs in Brachyuran according to gene arrangement features and sequence data sets. We also sequenced regions of mitochondrial COI and ND5 genes in order to address the genetic structure of S.

本文以长江华溪蟹为代表，通过对线粒体基因组序列的测定，从基因序列和排列顺序2个方面探讨淡水蟹类在短尾类中的系统地位；并利用COI和ND5 基因的部分序列数据，对我国长江华溪蟹种群的遗传结构进行了初步研究。

CDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique, and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1335bP的片断编码444个氨基酸残基。

Insect resistance to Bt toxin is related with the variation of cadherin-like protein gene.cDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique,and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1 335 bp的片断编码444个氨基酸残基。

Although the panel logit models verify the effects of the explanatory variables consistently with the theory, the prediction accuracy is not as good as that of neuro fuzzy. In addition to the better out-sample prediction accuracy, neuro fuzzy also provides a more detailed and complicated relationship among the variables through the rule base mid 3-dimension graphics, which could be used for further theory development or modification Overall, the banking crises ca be predictable; however, each country needs different forecasting model. The mapping between the forecasting model mid data set characteristics ca be further developed for the future research.

实证结果显示，虽然Panel Logit之固定效果与随机效果模型皆验证了过去理论上各变数对银行危机之影响方向，但整体而言，其预测准确度并不比类神经模糊好；而类神经模糊除了提供更准确的样本外预测之外，其所建构的规则库与3D图提供较以往更为细腻的变数关系，此关系可作为未来理论发展之基础；整体而言银行危机可以被有效的预测，然而单一国家的预测结果显示不同的国家适用不同的预测工具，没有一项工具能够适用於所有的国家；而资料集属性与预测工具之对应关系可作为未来之研究方向。

If you have supplied a handler for a specific message, or for a range of messages, in your parent window's class, it will override reflected message handlers for the same message provided you don't call the base class handler function in your own handler.

如果你在控件的父窗口类中为一个或一定范围特定的消息提供了一个处理函数，对于同样的消息，如果在您的处理中您并没有调用其基类的处理函数它就会覆盖掉被反射的消息处理。

In this study, dichlorodiphenyltrichloroethane, hexachlorocyclohexane and chlordane were measured in 23 aquatic organism samples collected from Deep Bay, South China. Results showed that, the concentrations of DDTs, HCHs and CHLs in fishes were in the range of 1.84~286.83, 0.08~1.85 and 0.45~118.81ngg^(-1), respectively.

为了更好地理解深圳湾有机氯农药的污染现状及其生物累积规律，于2004年2月采集了该海域23个鱼类、虾类、蟹类生物样品，分析了其体内滴滴涕、六六六和氯丹各组分的含量，并对其人体健康风险进行了初步评价。

In this paper, we get the fractional chromatic number about several kinds of graphs. And according to these results we get the chromatic number on these graphs.

文中给出了一些图类的分数色数，并根据这些结果得到了其中一些图类的顶点色数。

With the help of this variable, a much better model is obtained. Its estimation errors and prediction errors are all very small closing to the measurement error level.

另外，当用一种同系物系列中的化合物构建投影方向时，能得到一个针对同系物的分类，并由此提出了类距离变量，用类距离变量可以建立非常优良的构性关系模型。
