Finally, the meaning of these characters in phylogeny were discussed.

最后对上述特点在系统发生中的意义进行了讨论。

The CuZnSOD also appears to be associated with the plastid but is phylogenetically more restricted in its distribution.

Cu，Zn-SOD也与质体相关，但是从系统发生学角度来看，这更多是局限于在质体中的分布。

In polyphase power systems with some number of phases other than three, this effect occurs with harmonics of the same multiple.

在多相电力系统以外的一些数量三个阶段进行，这一效应多发生在同一谐波。

In the power system failure transient period of time.

在电力系统发生故障的暂态时期内。

In order to deal with the stochastic characters of fault location, fault type, fault clearing time, and load level etc., this paper proposed a transient stability probability analysis method based on curve fitting.

考虑电力系统发生故障时，故障位置、故障类型、故障切除时间以及负荷水平都具有随机性，提出了一种基于曲线拟合的暂态稳定概率评估方法。

"In order to prevent potential scald injury, install an antiscald tempering valve in the water system."

为了防止可能发生的烫伤事故，请在热水管道系统上安装一个防烫伤调节阀门。

Secondarily , the paper infers to the over voltage multiple that it is likely to .

其次推导出系统发生谐振和误操作时可能出现的过电压倍数，并用实例加以验证。

We have identified 1452 GPCRs in the X.tropicalis genome.(2) Phylogenetic analyses classified these receptors into seven families, consisting of Glutamate,Rhodopsin,Adhesion,Frizzled,Secretin,Taste 2 and Vomeronasal 1.(3) X.tropicalis shares a more similar repertoire of GPCRs with mammals than it does with fish.

2严格的系统发生学分析将热带爪蟾G蛋白偶联受体分成了谷氨酸盐受体类，视紫红质类，粘着蛋白类，卷曲蛋白类，味觉2受体类，分泌素受体类和犁鼻骨1受体类这七个受体家族。

They say doing anything else would have sent shock waves to the financial system.

他们表示，发生的任何变数都将冲击整个金融系统。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
