肉眼

Nowadays, Olympic races have to be timed accurately to hundredths of a second.

古希腊裁判凭借肉眼做出判断，现在，奥运会的速度比赛必须被精确到百分之一秒。

The spectrum analysis shows that ① Infrasonic waves produced by meteor are mostly very short, lasting one to five minutes;②Periods of the infrasonic waves range mostly from 40 to 408 seconds, and a few waves range from 40 to 480 seconds;③ During 7:21 p.m. to 8:41 p.m. on Nov. 17, the infrasonic waves were much denser. After 8:41 p.m., the waves become more and more sparse, all waves conform to those observed with naked eyes;④ Amplitudes of infrasonic waves from meteor differ significantly from each other (weaker ones below 5 to 10 Pa, medium ones from 10 to 20 Pa, and stronger ones from 20 to 40 Pa). Two of the strongest ones reach 75 Pa and 50 Pa respectively around 7:28 p.m. and 8:07 p.m. on Nov. 17. An explanation of above results is given.

频谱分析结果表明：①各流星产生的次声波大都很短暂，持续时间为1~5min；②流星次声波的周期大都在40~408s；③在1998年11月17日19：21-20：41期间流星次声波仍很密集，20：41后才变得越来越稀疏，恰与肉眼观测结果相符；④流星次声波的振幅彼此相差很大，较弱的在5~10Pa，中等的在10~20Pa，较强的在20~40Pa，最强的两个波在11月17日19：28和20：07前后分别达到75Pa和50Pa。

GCubik exploits the Integral Photography technology to enable 3D images to be viewed with the naked eye rather than through sophisticated 3D glasses.

gCubik利用积分摄影技术，使三维图像，还可以用肉眼而不是通过复杂的3D眼镜。

Methods: using number one fumigate-washing prescription, jieeryin, PP powder and physiologic saline cure respectively the wound of the experiment Jimpy mice which have suffered form anus operation. Then we observed the bacterial number of granulation tissue, the content of hydroxyproline, and the emerging of granulation tissue at the fifth day after operation, and the change of granulation tissue at the seventh and fourteenth days after operation.

以熏洗一号、洁尔阴、PP粉、生理盐水分别治疗小鼠实验性肛旁手术伤口，观察各组小鼠伤口肉芽组织中细菌数、羟脯氨酸量、术后第5天肉芽组织出现情况、7和14天肉芽组织肉眼及病理学变化。

Examination assurance:Knife quality management is an key and unseen job.Special examination room has been established to examine product quality through advanced equipments at any time.

检验保证：刀具的质量管理是一项用肉眼看不见的重要工作，本公司购进了先进的检验设备，成立物理化验室，随时进行产品质量检验。

If you have light on for 1/100 second and immediately after lig ...

如果你有1/100秒内能开启，1/100秒内能关闭的灯(我记得由于是交流电的原因，我们使用的电灯都应该是有时断现象的，可由于时间很短，而我们的肉眼是分辨不出来的——客户大概意思是能快关快开)，你看不到

The molecular switch consisted of a [2]rotaxane with a dumbbell component that had dibenzylammonium and 4,4'-bipyridinium "stations" that were able to "lock up" the ring-shaped component known as a macrocycle.

在不同pH值的条件下，藉由TTF与[2]车轮烷之间电荷转移吸收改变所造成的颜色变化，使一般人可凭肉眼观察颜色来判别其操作状态。

Cinnamomea fruiting body. The malt extract agar was the basic medium used in this study. The standard MEA formula was designated as 100%, and a series of dilution of the MEA were made to culture A. cinnamomea. During the culture period, we determine the formation of fruiting body by visual and microscopic observation on A.

把标准的MEA配方视为100%，对其做一系列的稀释，用来培养樟芝，在培养的过程，发现子实体的形成，以肉眼和显微镜判断其多孔性状的生成，再以HPLC进行分析。

As Gomez, Folsome, and Pimm discovered in their microcosms, it can take 60 days for the microbes to settle into a stable community.

像生物圈二号一样，海水养鱼缸是一个精致的闭合系统，较大动物和植物的废物全靠这个世界里肉眼看不见的微生物处理。

Three or four naked-eye planets and a number of bright stars may be visible during totality.

三个或者四个肉眼可见的行星以及许多明亮的恒星也许能在全食阶段看到。

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。
