序列性

Since nonparameter seasonal Kendall test may result in error in total trend analysis of the whole year or many stations when there exist uptrends and downtrends among different seasons or stations, a consistent test method of the total trend is recommended to solve this problem so as to perfect nonparameter seasonal Kendall test.

第三章首先分析了河流水质序列中的几种变化趋势类型，综述了国内外用于趋势检验分析的各种方法，归纳出非参数季节性Kendall检验方法为较理想的方法，然后针对该方法在进行总趋势分析时可能出现的站与站之间、季节之间上升、下降趋势的相互抵消问题，提出了趋势纯一性检验方法，并把这些方法应用于淮河流域56个水质站的趋势分析，取得了满意的结果。

A-share index of Shanghai Stock Exchange, the B-share index of Shanghai Stock Exchange and Shanghai Stock Exchange composite index return series obviously are fat tailed, with excess kurtosis.

本文得出的结论如下：一、上证A股、上证B股和上证综合指数收益率序列明显具有尖峰厚尾的性态。

Molecular homology trees were constructed based on the amino acid sequences of the RdRp,CP and MP,and the results showed that TVDV shares much more homologous with the specieses of the genus Polerovirus than other genuses of family Luteoviridae,which indicated that TVDV should be a definitive member of the genus Polerovirus in the family Luteoviridae.

根据三个ORF编码的氨基酸序列构建的分子同源树的分析，也都显示了TVDV与黄症病毒科马铃薯卷叶病毒属病毒的同源性最高，进一步证实了TVDV应该是黄症病毒科马铃薯卷叶病毒属的确定成员。

Homology analysis demonstrated that, McChi5 protein, which contained a conserved domain of family 18 glycosyl hydrolyse, had the sequence similar to tabacco class V chitinases, several putative chitinases and chitinase-like proteins of Arabidopsis thiliania , and some chitinases from mammals, insects and bacteria.

同源性分析表明，McChi5蛋白与烟草V类几丁酶、拟南芥的推测几丁酶和类几丁酶蛋白、以及哺乳动物和细菌的一些几丁酶有序列相似性，并具有第18家族糖基水解酶的保守域。

In nucleotide level, both the coding sequence and 5' intron sequence are very conservative.

在核苷酸水平上，不但编码序列具有较高的保守性，而且内含子的5'端也是非常保守的。

It is located in chromosome 2 (2P13) and has one more intron sequences of BARD1 gene.

结果：55个克隆的核苷酸序列代表45个卵巢癌抗原基因，其中8个是国内外首次发现的在GeneBank中尚未登记的新基因，这些新基因都是具有免疫原性的功能基因。

In this study, PCR-RFLP and PCR-SSCP analysis were commanded on the Intron 17 and 18 nucleotide sequences of KIT gene.

通过利用PCR-RFLP和PCR-SSCP技术对中国地方猪种KIT基因内含子17、18的序列进行多态性分析。

In the first chapter, we used the method of majoring sequences to studied the convergences of Newton s methods of " reducing the counting of derivative" and "without inversing of derivative under weak conditions".

在第一章中，用优序列方法研究了减少导映照计值次数和避免导映照求逆的牛顿迭代在弱条件下的收敛性。

However,one theory or method alone can not work elfectively.On account of the thought of integrative prediction,three modelings are combined to forecast the annual runoff.

近年来，在反演建模的基础上发展了基于时间序列的数据机理—自记忆模型理论[1]，自忆性原理是将决定论和不确定论两种方法融合在数学上的实现。

The monophyly of monocots receives 98% bootstrap support in the combined analyses of three genes.

单子叶植物的单系性在3个序列联合分析中得到98%的强烈自展支持。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
