In particular, compared with conventional fluorophores, the long-lasting phosphorescence nanotubes have a broad and continuous excitaion spectrum and are photochemically stable, which can be used as fluorescent probes in biological staining and diagnostics.

对于纳米结构的长余辉材料来说，它们在纳米器件的标记和显示上具有较大的应用前景。特别是对于纳米管状结构的长余辉来说，它们具有宽的连续发射带和光化学稳定性，使得它们在生物着色和诊断上可以用做荧光探针。

After plasmodia infect a blood cell, they send out clusters of sticky proteins to the cell surface, enabling them to attach to blood vessels and escape destruction by the host's spleen while they replicate.

疟原虫感染血细胞后，它们会向细胞表面释放出一系列粘性蛋白质，使其能够附着在血管上，以便逃避它们复制时宿主脾脏对它们的破坏。

Bunnies suffer horribly in cages and must be litterbox trained so that they can live happily in your home, but if your home isn't rabbitproof, they will sharpen their teeth on electrical wires, house plants, or your new IKEA chaise or oak table.

兔子在笼子中会担惊受怕，必须训练它们使用便盆，以便让它们在家里快乐自由地生活，但如果你家里没有&兔子窝&，它们可能会在电线上，室内植物上，或你新的宜家家具或橡木桌子上磨牙。

After thirty-five generations, the two groups and their offspring were isolated reproductively because of their strong habitat preferences: they mated only within the areas they preferred, and so did not mate with flies that preferred the other areas.

经过35代，这两个果蝇群出现生殖隔离，因为它们有强烈的生境偏好：它们只在它们喜欢的区域交配，因此不与喜欢其它区域的果蝇交配。

Hence the growth of a large number of small factories, which are owned by a few multi-skilled and ever-retrained worker-engineer-managers, and equipped with precision, resettable machines working specialty materials like stainless steel and titanium.

因而兴起了一大批小工厂，它们的老板是少数掌握多种技术，不断接受再培训且集工人、工程师和管理者于一身的人，它们装备有精密的、可重新调装的机器，它们所加工的是特种材料，像不锈钢和钛等。

However the depth at which they will be seamed together is exactly the same measurement.

无论它们的长度着别多少，当它们缝合后，它们的长度当是一样的。

Skutterudite compounds are a newly-developed family of TE materials. They exhibit excellent electrical transport properties; however, their thermal conductivity is too high to be good thermoelectric materials compared with traditional alloy TE materials.

中文摘要方钴矿化合物是近几年发展起来的一类新型热电材料，它们具有优异的电输运性能，但是相对较高的热导率降低了它们的热电转换效率，从而限制了它们在热电领域的应用。

But the electrochemical results show that complexes exhibitcompletely irreversible redox behaviour which is different from thatfound in diiron proteins. 1.3 To obtain the diiron species which are stable to elec-trochemical reduction, a series of new tetranuclear cage ironspecies containing two 〓 cores, with using hexadentatepolybenzimidazole ligands, were synthesized and characterized by vari-ous spectroscopic methods. Their physical properties have been investi-gated. The crystal structures of 〓〓tetrakis (benzimidazol-2-ylmethyl)-1, 4-diaminobutane and 〓,〓-tetrakis ( N-ethylbenzimidazol-2-ylmethyl )-1, 4-diaminobutane were determined. They contain two 〓 cores which arelinked to each other by -〓-chain in the ligands.

1.3为了获得电化学还原稳定双核氧桥联Fe化合物，使用六齿配体合成了一系列含有两个〓单元四核笼状化合物，并用各种谱学手段表征了它们，还研究了它们的物理化学性质确定了〓L=N，N，N'，N'-四(苯骈咪唑基-1，4-丁二胺和〓，〓四-1，4-丁二胺化合物的晶体结构，它们含有两个〓单元，其中两个〓单元是通过配体的〓链桥联成四核笼状结构。

A folugub is a beetlelike creature 6 feet long and 3 feet high, weighing about 180 pounds. Its protective carapace gleams and glitters with a crystalline sheen. A tonguelike organ flickers from between its mandibles every few seconds, reaching to a length of 3 feet. The tongue liquefies crystal objects on contact, which the folugub then slurps up.

溶晶怪外形像甲虫，它们3尺高，6尺长，重180磅左右，它们保护性的甲克闪耀着水晶的光辉，而它们那可以伸3尺长的舌头状口器则可以仅凭接触就溶解大部分水晶，而此时溶晶怪便吸食之。

These he had, and nursed them, loved them, and cared for them with earnestness and capability, and the family knew that, but they did not hide from him thatwhen visiting they often ate fruit and saw flowers which excelled what they had in their own garden,and that dis- tressed the gardener, for he wished to do his best and he did his best.

这就是他忙的几块地方。他热情地、内行地保养它们，爱护它们和照顾它们。主人都知道他勤快。但是有一件事他们却不瞒他：他们在别人家里看到的花儿和尝到的果子，全都比自己花园里的好。园丁听到非常难过，因为他总是想尽一切办法把事情做好的，而事实上他也尽了最大的努力。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
