筛选

Tracing the history of the hairbrush is akin to sifting through a haystack for a needle.

追踪历史上的发刷类似于筛选大海捞针了针。

So I think university managing enterprise is not worth the candle get more kicks than halfpence.

具体讲就是，一方面大学从校办企业中彻底撤离出来，让企业自主的走向社会，接受市场的筛选。

The moderate halophile strain Nj223 was selected from Prydz Bay deep-sea sediment and identified by 16S rDNA as Halomonas sp.

对普里兹湾深海沉积物中筛选到的中度嗜盐菌盐单胞菌Nj223Halomonas sp。

The model,based on the solution space of Hamiltonian problem,fixes the DNA molecules of solution space on the solid carrier,and fluorescence labels on them,and then gets all solutions of Hamiltonian circuit problem by certain biochemical actions.

该模型基于哈密尔顿回路问题的解空间，将问题解空间的DNA分子固定在固体载体上，对其进行荧光标记，然后通过相应的生化反应筛选出哈密尔顿回路问题的所有解。

The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

摘 要：采用两台JVC3000高速摄像机对中国女子链球优秀运动员张文秀的技术动作进行三维摄影测量，获得较为全面的人体运动学数据；运用SPSS软件对数据进行筛选和相关分析，发现该运动员在旋转时间、轨迹和速度等技术参数方面存在着一些制约成绩提高的问题，诸如双支撑时间短于单支撑时间、各圈(尤其第1圈)的轨迹倾角偏大、加速过程太短、单支撑阶段过于强调加速及双支撑阶段旋转过快、持续加速能力不强等。

Initial experiments, reported recently in the Journal of Animal Science, show that the process does not affect the hatchability of tested eggs, and appears to be virtually foolproof, if rather long-winded (the results are available only after two hours).

最初的实验最近在《动物科学》杂志上发表，实验表明上述筛选过程并没有影响实验样蛋的孵化率。并且即使是在相当繁琐的情况下（得到实验结果一般需要两个小时），实验结果也似乎是可靠的。

The authors have separated and purified four strains that can b e used to decompose the cellulose and starch at a great rate from the zymotic wa ste,starch factory's sludge and putrid haulm.

从发酵的垃圾、淀粉厂污泥、腐烂桔杆等样品中，分离、纯化、诱变、筛选出分解纤维素、淀粉能力较强的 4种菌株，按不同比例混合制备出有机固体废物发酵剂。

Hawley sketches for members of Congress 19 security steps the TSA employs before, during and after checkpoint screening."Each and every one of these 19 security layers is important and strong in its own right," he says."Linked together, they are effective and daunting."

他描述了安检的19个步骤，在筛选检查之中及后面的步骤对自身来说，19个步骤的任何一环都是重要和强大的，把它们很好地联系在一起，则会发挥出高效和令人畏缩的作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
