系统发生

Some problems exist in the traditional protection method: it may perform maloperation in time of power swing; the existence of transition resistance may result in tripping missing or maloperation.

但是距离保护的性能也存在一些问题：当系统发生振荡时距离保护可能会误动作，过渡电阻的存在可能会使距离保护误动或拒动等等，这些对距离保护的性能有很大的影响并且难以避免。

The freshwater crab phylogeny suggested that the genus Sinopotamon and the genus Potamonautes arose from a common ancestor and the estimated divergence time is about 36～44 Mya.

淡水蟹类的系统发生研究显示，华溪蟹属与仿溪蟹属起源于一个共同的海生蟹类祖先，二者之间的歧异时间在36～44Mya。

The phylogenetic analysis of these two nonmarine crabs together with intertidal, supratidal and swimming crabs based on portions of mitochondrial 16S rDNA sequences suggested that Grapsioidea, Ocypodoidea, Potamoidea and Portunoidea arose from a common marine ancestor, and the estimated divergence time are similar.

基于线粒体16S rDNA部分序列，对这2个类型的非海洋蟹类与潮间带蟹类、海洋蟹类之间的系统发生分析提示，方蟹总科、沙蟹总科、溪蟹总科和梭子蟹总科的蟹类起源于一个共同的海洋蟹类祖先，它们彼此之间的歧异时间基本一致。

Important incidents occulting in station or system should be announced to all control rooms by the shift engineer in charge.

值长应将电厂或系统发生的事故通告所有的控制室。

The birds of Passeriformes are the group which are the largest number, the most species, the highest station of evolvement and the broadest adaptive radiation of existent aves. The traditional taxonomy were onlyaccording to morphologic and behavioral characters, however their morphologic and behavioral characters are so complicated that we could not differentiate some species easily. Therefore we had some taxonomic research by molecular means in order to supply traditional taxonomy.

雀形目是现存鸟类中种类最多、数量最大的、演化地位最高、适应辐射最广的类群，传统的分类方法仅依据形态和行为特征来划分，但由于该类群的形态及行为特征复杂使得部分种类不易区分，因此有必要依据分子手段研究其系统发生关系、以盼能对经典的分类方法给予补充。

In this study, reliable phylogenetic relationships of eight species in Pectinidae were inferred from the structure alignment, but not from sequence alignment, even with the aid of structural information.

本研究的结果显示，可靠的系统发生关系可以从完整的二级结构比对中推断得出，但不能从序列比对中推断得出。

The estimated number of nucleotide substitutions per site between genera Phasianus and Chrysolopus is 0.076 (rangs from 0.067-0.085), and between golden and Ch...

在雉科系统发生中，雉属与锦鸡属是近缘的属；2。红腹锦鸡和白腹锦鸡的分化较晚，关系密切，可能只是两个亚种。

The animal's way of "interpreting" a problem situation becomes more and more similar to that of humans as the experimental animal is phylogenetically closer to man.

动物「解决」困难情境时的方法，变得越来越与人类相似，正如被试验的动物有系统发生的接近人类。

Even studies of phylogenetically disparate species, such as songbirds, can suggest to us some things about what we humans are doing and, conceivably, how we might be doing them.

甚至是对那些在系统发生上和我们人类在本质上根本不同的动物的研究，比如对鸣禽的研究，也能够向我们揭示出一些关于&人类在做什么&和&人类是怎么做的&这样的信息的。

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。
