有生物的

Many phytoplankton and autotroph absorb the DIN of the bottom water that decrease content of DIN in bottom water and change the fluxes of the DIN. And the activity of those phytoplankton and autotroph can even change the direction of DINS fluxes.

在有光的条件下，浮游藻类和一些光自养生物对沉积物水界面溶解态的营养盐的直接吸收，从而减少了上覆水中可与沉积物可交换的营养盐的含量；浮游植物的活动甚至有可能改变无机氮在沉积物水界面的扩散方向。

For there was no other donor but himself, and while his physique was close enough to the human to make little difference on the operation table, his DNA typing was a biological puzzle yet unsolved, unduplicable unless he was alive and able to supply the template for growth structuring.

因为没有其他的捐赠人但是他自己，而且当他的体格对人类够接近来有在手术桌子上的小不同的时候，他的 DNA 打字是一个生物的谜题然而未解决， unduplicable 除非他是有活力的和聪明为生长构成供应型板。

The glaciers, perhaps 200 million years old, also may entomb genetic fragments of past microbial life on Mars as well as air bubbles that might reveal the composition of the atmosphere as it was long ago, according to geologist James Head of BrownUniversity in Providence, Rhode Island.

根据 Rhode Island 州 Providence 大学地理学家 James Head of Brown 的说法，这块大约有2亿年的冰河可能会藏有火星过去生物的基因碎片，也可能会有一些气泡。这些气泡里的空气会表明多年以前火星大气的成分。

We need to know the importance of big,mature trees,because living space for most of man's fellow creatures on this planet is figured not only in square measure of surface but also in cubic volume above the earth.

我们需要知道成熟的大树的重要性，(60)因为除人我们需要有人教我们，告诉之外，其他生物的生存空间。不仅仅有平面上的，还有立体上的。

The inclination to goodness, is imprinted deeply in the nature of man; insomuch, that if it issues not towards men, it will take unto other living creatures; as it is seen in the Turks, a cruel people, who nevertheless are kind to beasts, and give alms, to dogs and birds; insomuch, as Busbechius reporteth, a Christian boy, in Constantinople, had like to have been stoned, for gagging in a waggishness a long-billed fowl.

向善的倾向是在人性中印得很深的；怎样深法？就是如果这种倾向不发向人类，也要及于别的生物的；这可由土耳其人见之，土耳其人是一种残忍的民族，然而他们对待禽兽却很仁慈，并且施舍及于狗只和雀鸟。据布斯拜洽斯底记述，君士坦丁堡有一个基督教青年，因为在玩笑中撑住了一只长喙鸟底嘴的缘故，差一点被人用石头打死了。土耳其人爱物的程度有如此者。

Through the research, the author found the true facts that are Arhorchin Mongolian ethnobotanical knowledge not only have a historical contribution to the development of indigenous society, but also have a very important applicable value and practical significance to the exploitation, utilization and conservation of grassland plant resources, to the management of grassland ecosystem, pastoral community development, conservation of biodiversity and cultural traditions, and development of Mongolian national educations of society, economy and environment.

通过本项研究发现，阿鲁科尔沁蒙古民族植物学知识不仅有其历史的贡献和作用，而且在现代社会、经济和环境条件下，对于草原区植物资源的开发利用和保护、草原生态系统的管理、牧区村社发展、生物多样性和相关文化保护以及蒙古民族教育、科学、文化的发展均有重要的应用价值和实际意义。

Of creatures possessed of hearing, some have ears, whilst others have none, but merely have the passages for ears visible, as, for example, feathered animals or animals coated with horny tessellates.

在拥有听力的生物中，一些有耳朵，同时其它的没有，只有可见的听觉作用通道，像是有羽毛的动物或者覆盖着坚硬鳞甲的动物。

A single figure in each rises and pulls its dark hood over its smooth, finned head. One motions toward the dense swamplands to the east. The strange figures seem even more out of place silhouetted against their bulkier, less agile troll allies; yet their authority is unquestioned.

每艘小艇旁都有一个人影浮现，这些人影将黑色斗篷拉下，盖住那光滑且有鳍的头部，并向东边的沼泽方向做了个手势，这些带有黑暗力量的奇怪生物在型体上似乎跟他们巨大且笨重的洞穴巨人盟友格格不入，但是他们的影响是无庸置疑的。

The homeodomain is responsible for binding to DNA, and experiments to swap homeodomains between proteins suggest that the specificity of DNA recognition lies within the homeodomain, but (like the situation with phage repressors) no simple code relating protein and DNA sequences can be deduced.

同源域负责结合DNA，在蛋白质之间交换同源域的实验证实了这一结论。但（就像噬菌体阻遏子的情形一样）并没有推出联系蛋白质与DNA序列的简单机理。同源域的C端和原核生物阻遏子α-β-α超二级结构有一定的同源关系。我们回想第13章，λ阻遏子有一个&识别螺旋&（α-螺旋-3）DNA的大构接触，而另一个螺旋（α-螺旋-2）位于 DNA的拐角。

The doses estimated by accident reconstruction were about 30,30and 20 R and the doses estimated with chromosome aberration were about 46,26 and 26 rads respectively.The results obtained by above two methodsagreed quite well.In accident 2,all 8 cases of exposed workers...

在事故2中，受照者8人，均佩有胶片剂量计，其剂量记录从1.6到20伦不等；用染色体畸变方法，以无着丝点畸变和击断率为指标，在计数200和500个左右的细胞时，用我们实验室所作的刻度曲线，分别进行了剂量估算；结果表明，在较低剂量的~(60)Coγ射线照射事故中，当计数500个左右的细胞时，上述&生物剂量计&仍有一定的参考价值。

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。
