生命化学的

In the course of evolution, when life emerged from the sea in the form of amphibia, a general chemical-sensitive system likely separated into two anatomically distinct but functionally united mechanisms to take into account the chemical information occurring in two different environments, one inside the body—taste or gustation—and one outside—smell or olfaction.

在进化的过程中，当生命以两栖类的形式从海洋里出现时，可能这一种主要的化学感应系统就分成了两种在解剖学上独立但功能上联合的器官。这种器官用来通过两种不同的环境分析化学信息。一种是在分析体内环境的，这就是味觉。另一种分析体外环境的，这就是嗅觉。

Tissue engineering is a new rising subject with the development of life science,materials science,chemistry science,its core is to establish three-dimension comples of cell and biological medical materials,that is also the living tissue with vitality,which can be used to reconstruct the morphosis and function for damaged tissue and then to achieve permanent replacement.

组织工程是近年来随着生命科学、材料科学及相关物理、化学学科的发展而兴起的一门学科，其核心是建立细胞与生物医用材料的三维空间复合体即具有生命力的活体组织，用以对病损组织进行形态结构和功能的重建并达到永久性替代。

Over break 3. But even assuming that a planet is the right size and has the proper chemical composition and a stable orbit neither too far from its star nor too close, so that its temperature is at all times in the range of liquid water (as is true of Earth except for the polar regions), a great deal would stilldepend on the kind of star it was revolving about.

over break 但是即使假定有一颗行星，它的大小正好，化学成分适宜，运行轨道稳定，与恒星的距离既不太远也不太近，气温始终保持在液态水温的范围内（正如地球上极地以外地区的温度一样），那儿是否存在生命，在很大程度上仍得取决于它所围绕运转的是什么样的恒星。

It obtains the various optical images of the sample's nanometer surface, transcended the diffraction limit of conventional optical microscope, by using a fine optical-fiber tip probing ultra-high frequency optical information on the sample surface. And it has extensively been applied on life science, chemistry and material science fields.

它利用细小的光学探针探测样品表面隐失波的超高频空间信息，超越经典衍射极限的限制，可对样品表面纳米尺度区域的各种光学信息进行扫描成像，在生命科学、化学及材料科学领域中都有着广泛而重要的应用。

Representation of panspermia - a theory that the seeds of life are found throughout the universe, and that life arose on Earth when such seeds landed here early in Earth's history.

&有生源说&是胚种论的一种学说，该理论认为地球上的生命是由搭顺风车，乘撞击地球的小行星或彗星的细菌或是生物化学物带来的。

The instrument may be used in measuring sheat wave resonant absorption spectrum of liquid film in 1x10 to the power -5 -500 Hz frequency range and in providing measurement data for the research of the interaction range between clusters, long chains and multibands of liquid film, the group behavior of molecules and clusters, the long chain in polymer solution, the second, the third and the fourth group behavior in left liquid and other group behavior in chemical solution and complex.

本发明的谱仪可在10 －5 ―500Hz频率范围内，测量液体膜的切变波共振吸收谱，为研究溶液中的团簇间、长链间和多键间的交互作用范围，分子和团簇的集团行为，高分子溶液中的长链，生命液体中的二、三、四级或其他化学溶液和络合物中的基团的行为提供可靠的测量。

Pass to currently the design,questionnaire of the study,teaching plan of research,related theories of the Protestantism material and it tidies up the analysis and teacher the interview, promote migration of the chemistry knowledge,expand with the conversion, make the student's better study life science.

通过对目前新教材的研究、相关理论的学习、教案的设计、问卷调查及其整理分析和教师访谈，促进了化学知识的迁移、扩展和转化，使学生更好的学习生命科学。

Whatever else it may be, at the level of chemistry life is curiously mundane: carbon, hydrogen, oxygen, and nitrogen, a little calcium, a dash of sulfur, a light dusting of other very ordinary elements-nothing you wouldn't find in any ordinary drugstore-and that's all you need.

不管原子还可以形成什么，从化学角度讲，生命的构成元素是极为普通的：碳、氢、氧、氮、少量的钙、少许的硫、再一些普通的别的元素。这些可以在任何一家药房找到。

Others are said to have redundant, but many also been a time when life is not to touch the East West gourd dipper touch, follow the crowd, and even Zhi Shen, away from reality, the choice of a road, only the prospect of dazzling, this is not a mathematical problem, Is not a chemical formula, but rather a philosophy of the proposition that this proposition, we have to read it out of it, and grasp the opportunity to grasp its own life big sail, to do my own life drivers.

其他说来也都是多余的，但众多人生又何曾不是东碰葫芦西碰瓢，随波逐流，甚至于沉乿，从实际出走，选择一条道路，才有光彩夺目的前景，这不是一个数学问题，更不是一个化学公式，而是一道哲学的命题，这一命题，我们要读懂它，摆脱它，把握机遇把握自己大人生船帆，做我自己的生命的驾驶者。

This edition freeduan.com includes discussions of new extinguishing agents, including wet chemical and clean agents designed to replace halon and a more in-depth treatment of hazard control and Life Safety issues.

这版freeduan.com 包括新熄灭的代理人的讨论，包括潮湿的化学制品和干净的代理人用于替换halon 和更多的详细的处理危险控制和生命安全问题。

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。
