The coordination mode of La can be described as a distorted aquare antiprism, which was completed by two oxygen atoms from one oxalate, four oxygen atoms from four different PDC ligands, and two oxygen atoms from two water molecules.

La呈现四方反棱柱体的配位模式，分别和2个来自同一个草酸配体的氧原子、4个来自4个PDC配体的氧原子以及2个来自2个配位水分子的氧原子配位。

Though sometimes he was blindfolded ,no man nor god ,zeus himself included ,was safe from his evils.at one time the little naughty god was wounded by his own arrows and suchburning love was awakened in him for the human maiden psyche that he disregarded the constant interference of his mother and plucked up his courage to beg zeus for justice.another famousstory where eros played an important part was the argonautic expedition.medea ,daughter of king aeetes ,was wounded by eros'' arrows,took jason''s part in recovering the golden fleece and eventually became the hero''s wife.

给自然界带来生机，授予万物繁衍的能力。这位可爱而又淘气的小精灵有两种神箭：加快爱情产生的金头神箭和中止爱情的铅头神箭。另外，他还有一束照亮心灵的火炬。尽管有时他被蒙着眼睛，但没有任何人或神，包括宙斯在内，能逃避他的恶作剧。有一次这位淘气的精灵被自己的箭射中。对人间少女普赛克炽热的爱在他心中复苏，以致于他不顾他母亲的干预，鼓起勇气让宙斯给予公正评判。厄洛斯起了重大作用的另一个著名的故事是亚尔古英雄的远征。美狄亚，国王埃厄忒斯的女儿，被厄洛斯的神箭射中，和伊阿宋一起寻觅金羊毛，最后成为这位英雄的妻子。

Three patients (1.2%) had prolonged asystole. One young girl and two elderly males with atrial fibrillation.

三位(1.2%)病人有长的心跳停止，包括一位年轻女性及二位有心房颤动之年长男性。

The Pentagon already routinely uses robotic aeroplanes known as unmanned aerial vehicles. In November 2001 two missiles fired from a remote-controlled Predator UAV killed Mohammad Atef, al-Qaeda's chief of military operations and one of Osama bin Laden's most important associates, as he drove his car near Kabul.

目前，美国五角大楼已经开始例常使用一种机械自动控制的战斗机，并取名为无人驾驶空中飞行机。2001年11月，美国军方使用了遥控空中飞行机&掠夺者号&发射了两枚导弹并成功击中了两位恐怖分子，一位是执行阿凯达军事行动的长官，名叫穆哈曼德·阿特夫；另一位则是奥斯曼·本·拉登的一个最重要同志，当时他正驾车行驶于喀布尔附近的路上。

There are 73 families, 139 genera and 179 species distributed in 0 1 ha of different land Use Stages of Daka and 70 families 146 genera and 166 species distributed in 0 08 ha different land use stages of Baka, Xishuangbanna.

与热带雨林相比较，广布种由 1 0 %分别上升为 2 0 %，而且排位由第 9位分别上升到第 3位和第 3位，表明热带山地不同土地利用阶段造成植物区系成份中热带种和亚热带种优势减小。

There are large niche overlaps between the shrub and semi-shrub species and among the herbaceous plants of which the overlap between H. scoparium and A. ordosica and between Chloris virgata and Bassia dasyphylla were 0.7192 and 0.8622, respectively, and this indicates that they have greater ecological similarity thus possessing strong competitive capacities in community succession; there are smaller niche overlaps between A. ordosica and various herbaceous plants and thus they can stably co-existed.

灌木、半灌木种之间、草本植物与草本植物之间的生态位重迭值较大，其中花棒与油蒿、虎尾草与雾冰藜之间的生态位重迭值分别为0.7192和0.8622，这表明二者之间有较大的生态相似性，从而在演替过程中具有较强的竞争作用；而半灌木油蒿与各草本植物之间的生态位重迭值很小，它们能够实现稳定共存。

The results show that the introduction of 2-, 3- and 4- substituent of group leads to a bathochromic shift of position of the maximum absorption wavelength λmax, and also increases the molar extinction coefficient εmax.

2位、 3位和4位引入取代基可使酚类化合物的最大吸收波长λmax发生红移，摩尔消光系数εmax明显提高。

Microcalorimetric measurements of NH~3 adsorption on catalysts reveal that the remarkable strong acidity and catalytic activity of the Al- promoted catalysts are caused by a change of distribution of acid site strengths and an enhancement in the number of strong and intermediate-strong acid sites effective for the n-butane isomerization and benzoylation of toluene.

NH~3吸附微量热结果表明，Al促进样品的强酸性和催化活性的显著提高是由于样品表面的酸位强度分布发生了变化，有利于正丁烷异构化反应和苯甲酰化反应的中强酸位和强酸位的酸量显著增加。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
