Eutopia seated in the Brain.Fraud, Luxury, and Pride must live; [415]We we the Benefits receive.Hunger's a dreadful Plague no doubt,Yet who digests or thrives without?To the dry, crooked, shabby Vine? Which, whist its

红灯时时闪耀，似乎有意让你历数一路上到底有多少个路口，而且为了防止遗漏，有几个路口还有意要你停下来两三次？。。。

If it hadn't been raining as I came out of the cinema, I should have walked home; my apartment was nearby and the route anything but complicated—straight down the boulevard, crossing two streets and turning right on the third, the Rue de Grenelle, for about half a block.

如果我从电影院出来的时候没有下雨，我就可能已经走回家了。我的住所就在附近，怎么走非常简单--沿着林荫大道走，穿过两条街道，在第三个路都的时候向有拐，Rue de Grenelle ，大约半个街区。

Results show that intramolecular hydrogen transfer is not favored in view of the energy trend along IHT coordinate in the region such as hypericin's peri region, where two hydrogens of hydroxyl groups bond with a common oxygen of carbonyl group and exists two IHBs in the peri region. However, intramolecular proton transfer often occur in the molecule with hexahydric cycle hydrogen bond, where only one pair of adjacent hydroxyl group and carbonyl group.

此外选择设计了一个具有三个分子内氢键的体系，兼具金丝桃蒽酮和其他苝醌类光敏剂的分子内氢键特点，研究表明两个羟基氢与共同的羰基氧形成的氢键由于存在较高的势垒，很难发生分子内氢传递，即具有金丝桃蒽酮端位结构的分子其分子内氢传递很难发生，而一般的能形成六元环状结构的分子内氢键体系容易发生分子内氢传递。

This paper analyzes the theory and methods of social network as well as its application in the filed of knowledge management. Two idiographic issues and three research aspect are recognized in this paper.

本文综合回顾了社会网络理论和社会网络分析方法在知识管理领域的应用历史，确认了两个具体的应用领域和三个研究方向。

Three-to-one was call "perfect", and two-to-one "imperfect". Rules existed also whereby single notes could be halved to doubled in value (imperfected or altered, respectively) when preceded or followed by other certain notes.

一个划分为三个被称为perfect，一个划分为两个被称为imperfect，这种规则也适用于以某个单音经过某些音符的前面或后面时的减半或者加倍（分别被称为&imperfected&或者&altered&）。

Taking Neon Genesis Evaneglion for instance, this dissertation expatiates the moderns" soul suffering and craving by construing from symbolism, psychoanalysis and philosophy angles distinctively. Eventually found that japonic manga and animation exhibits " sein and possession existence in deep level.

通过以上两个角度的阐述，最后得出日本动漫深层次体现的是&存在与占有&的生存方式，同时以《新世纪福音》为例展开详尽的论述，从象征、心理以及哲学三个方面分别说明了动漫作品所展现的现代人的彷徨和内心深处的需要。

Litsea citrata oil can be divided into citral,light and heavy fractions. Curves of liquid-gas equilibriums, relating to the citral-heavy system and citral-light system,in vacuum and steam were obtained respectively by equilibrium experiments.

基于山苍子油具有可分成轻组分、柠檬醛组分和重组分三个部分的特性，在真空和水蒸气系统中，分别对柠檬醛-轻组分体系和重组分-柠檬醛体系进行平衡实验，得到两个体系的汽液相平衡组成和相平衡曲线。

Said I; yes, says he; let fly then, says I, in the Name of God, and with that I fir'd again among the amaz'd Wretches, and so did Friday; and as our Pieces were now loaden with what I call'd Swan-Shot, or small Pistol Bullets, we found only two drop; but so many were wounded, that they run about yelling, and skreaming, like mad Creatures, all bloody, and miserably wounded, most of them; whereof three more fell quickly after, though not quite dead.

他说：&好了。&我就说：&凭上帝的名义，开火！&说着，我就向那群惊慌失措的畜生又开了一枪，星期五也开了枪。这一次，我们枪里装的都是小铁沙或手枪子弹，所以只打倒了两个，但受伤的却很多。只见他们像疯子似地乱跑乱叫，全身是血，大多数受了重伤；不久，其中有三个也倒下了，虽然还不曾完全死去。

"We are very pleased that the satellite is being shipped to the Baikonur launch base and we are looking forward to traveling to Kazakhstan for the August launch," said Peter Jackson, chief executive officer of AsiaSat."Our collaboration with Space Systems/Loral on this project has been very positive, and we expect to benefit from the company's long heritage of reliability in FSS satellites."

AsiaSat 5卫星基于劳拉太空系统公司的1300平台建造而成，携带了26台C波段和14台Ku波段转发器。C波段可扩展AsiaSat 2卫星的全亚洲覆盖范围，Ku波段覆盖范围包括三个高能光束，其中的两个光束将覆盖东亚和南亚，另外一个波束为在轨可控光束，能够定位并向卫星覆盖范围内的用户提供服务。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
