The ovule has been used as an excellent model system to study morphogenesis and organogenesis.

胚珠是研究器官形态发生和模式建成遗传分子机理的一个理想系统。

In body building, in order for the muscle development process to occur, there needs to be a high intensity stimulus placed upon the musculature system.

在机构建设，以便为肌肉发生发展过程，需要有一个高强度的刺激后，肌肉放在系统。

One of the mutant zebra fish has a reduced number of hair cells in neuromast of its lateral line system.

By use of the identification information, the poorly damped area and the regions of the grid affected by the mode are detected on-line.

利用辨识出的模态信息，可以在线监测大规模电力系统阻尼薄弱区域并及时发现故障发生区域。

When some of the measurements are lost, the system will reduce the dimension by orthogonal projection without changing the measurement model.

当发生部分数据缺失的情况，系统只需要通过正交投影方法将观测空间降维，而不需要改变观测模型，也不需要重新对跟踪滤波器进行初始化。

It is true that system could oscillate back-wards and forwards in this dead zone.

不过，系统在这个死区内可能会发生来回的振荡。

In our study, the increased HR indicate that the parasympathetic nerve system was predominant in vivo or the intracardiac sympathetic nerve enhanced its modulation in vitro.After treatment of Atr, the isolated heart was only controlled by the intracardiac sympathetic nerve.

如果离体前后交感和副交感神经支配心脏的程度相同，HR不应发生明显变化，本实验中离体后HR增加，表明离体前副交感神经系统占优势或者离体后心内交感神经功能亢进。

It is indicated that the involved species of this subfamily clustered into two clades: the first clade includes those of the genus Neptis, Phaedyma, Pantoporia and Lintinga; the second one includes those of the genus Parthenos, Moduza, Limenitis, Athyma, Lexias and Euthalia. The genus Limenitis is suggested to be monophyletic; and the genera Euthalia and Lexias proved to be sister to each other and form a monophyletic group. The genus Litinga appears to be more closely related to Neptini than to Limenitini.

基于Cytb基因的线蛱蝶亚科系统发育分析结果表明，所有线蛱蝶亚科聚为两大枝：第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属；第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属；其中线蛱蝶属非单系群，翠蛱蝶属和律蛱蝶属则为单系发生，并构成姐妹群；缕蛱蝶属与环蛱蝶族亲缘关系较近。

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。
