Elevated levels of both these chemicals lead to heightened alertness and stimulate the forlorn animal to call for help and search for its abandoner- generally its mother.

上述两种化学物质在哺乳动物体内的浓度水平的升高会导致它们的警惕性提高并且激励它们从他们的抚养者那里获得帮助--通常是他们的母亲。

The pump and the air blower already became present to produce the indispensable machinery, each has their form in national economy's all quarters, therefore understood that their performance is not big regarding the production help.

泵与风机已经成为了现在生产中不可或缺的机械，在国民经济的各方各面都有它们的身影，因此了解它们的性能对于生产的帮助来说不可谓不大。

Lowland trees may lean to this side and that, though it is but a meadow breeze that bends them or a bank of cowlips from which their trunks lean aslope.

低地处的树木会东倒西歪，虽然让它们东倒西歪的，不过是草地上吹过的一阵阵微风；或者，它们的躯干倾斜到一边，不过是由于一排野樱草的影响。

低地上的树木会东倒西歪，虽说使它们弓腰曲背的，不过是草地上吹过的一阵阵微风；或者；它们的躯干歪到一边，不过是由于一排野樱草的影响。

Atacama's barren high plateaus are home to the Aymara people, who raise llamas for their meat and wool.

这个沙漠是不毛之地的高原，也是南美的艾马拉人的家园，他们饲养骆驼是要吃它们的肉和用它们的骆驼毛。

The mascot in 2008 is a blessing Wa and they are five lovely little colleagues and their images integrated fish, giant panda and hide the image of antelope, barn swallow and Olympic Olympic flame respectively and expressed them to the contact of the ocean, forest, the earth, the sky and the fire.

2008年的吉祥物是福娃，他们是五个可爱的小伙伴，它们的形象分别融入了鱼、大熊猫、藏羚羊、燕子以及奥林匹克圣火的形象，表达了它们对海洋、森林、大地、天空和火的联系。

Consider the intimate and curious acquaintance one makes with various kinds of weeds —— it will bear some iteration in the account, for there was no little iteration in the labor —— disturbing their delicate organizations so ruthlessly, and making such invidious distinctions with his hoe,levelling whole ranks of one species, and sedulously cultivating another.

想想，人跟各种杂草都还可以结交得很亲热很奇异呢，——说起这些来是怪累赘的，劳动的时候这些杂草已经够累赘的了，——把一种草全部捣毁，蛮横地摧残了它们的纤细的组织，锄头还要仔细地区别它们，为了把另一种草来培养。

Their formulas are presented as following:( 1 ) [Co2C6H2(COO44]n ( 2 ){[Co2(C2O4)C6H2(COO4(H2O)4] -4H2O-(NH2CH2COOH)}n ( 3 ){[Co(H2O)6][Co(H2O)4C6H2(COO4] . 4H2O}n These coordination polymers have been characterized by IR,UV-VIS-NIR spectroscopes. The variable temperature magnetic susceptibilities(1.5-300K)of complex (1) and (2) have been measured and studied. Complex (1) and (2) exhibit the anti-ferromagnetic property. The spin-transition phenomenon of complex (2) takes place at 17K.

经X-光衍射测定，确定了它们的结构，分子式如下：(1)[Co_2C_6H_2(COO_4_4]_n (2){[Co_2(C_2O_4)C_6H_2(COO_4(H_2O)_4]·4H_2O·(NH_2CH_2COOH)}_n (3){[Co(H_2O)_6][Co(H_2O)_4C_6H_2(COO_4]·4H_2O}_n 研究了上述三种配位聚合物的红外，紫外—可见—近红外光谱，测定了化合物(1)和(2)在1.5—300K温度范围内的变温磁矩，对它们的磁性研究表明，化合物(1)和(2)均呈反铁磁性，并且化合物(2)在17K发生了自旋转换现象。

The mechanism of these transporters is of particular interest because of their role in the regulation of neurotransmission and as the site of action of drugs such as Prozac.

由于这些转运蛋白在神经传输调控中的作用，由于它们充当Prozac等药物的作用点，因此它们的机制是人们特别感兴趣的。
