镊

Leaves 3-veined. Male perianth lobes 4(or 5), valvate; female perianth lobes 4, subequal, shorter than achene.

叶3脉。雄花花被裂片4(或5)，镊合状；雌花花被裂片4，近等长，短于瘦果。

A numerical simulation of this model shows that one of the methods to improve the efficiency of an optical tweezer is to change variant conditions, such as the microrotors speed is in proportion to the lasers power and has a nonlinear relation with the beam's waist.

基于此种模型的分析结果表明改变环境参量是提高光镊工作放率的方法之一，如微转子转动速率与光镊的激光功率成正比，与束腰半径成非线性关系。

With the development of single moleculer manipulation.Much research work has been done on DNA by optical tweezer, magnetic tweezer, micropipe, and so on. All these work has opened a new area in molecuer biology.

随着单分子操作的实验技术的发展，人们通过光镊、磁镊、微吸管等等，研究DNA分子的力学性质，探索DNA与蛋白质的相互作用，为分子生物学的研究开辟了新的天地。

Theories and experiments about the optical tweezer are studied in detail. All kinds of micro-sized particles are trapped and manipulated by laser trapping. An useful device which is used to trap both transparent and opaque particulates is invented.

本人从理论和实验两方面对光镊技术进行了深入的研究，实现了光镊对各种微粒的捕获与操纵，设计实验装置对透明与不透明微粒捕获实现了统一。

Because of the use of novel technique of mode choosing and shape modifying to the high power infrared diode laser,and of manipulating the trap with dual-lens scanning, the tweezer is easy to be constructed and operated.

由于采用了独特的对大功率多模红外激光选模整形和双透镜陷阱操纵技术等性能价格最优化选择，该系统易于构建，陷阱操作方便，其构建价格仅一般光镊的几十分之一，非常适合光镊技术的推广和一般实验室构建。

Female flowers: sepals 5, often narrower than in male, imbricate to reduplicate-valvate, persistent, sometimes accrescent; petals 5, smaller than in male, mostly reduced or obsolete; disk annular or dissected, receptacle often villous; ovary 3-locular; ovules 1 per locule; styles 3, longer and slender, free or nearly so, once to several times bifid.

雌花： 萼片5，通常比雄花的狭窄，覆瓦状到外向镊合状的镊合状，宿存，有时增大；花瓣5，小于雄花，多数退化或废退；花盘环状的或多裂，花托经常具长柔毛；子房3室；胚珠每室1；花柱3，长和纤细，离生或近离生，1到数个2裂。

Sepals imbricate or valvate, rarely spathaceous, mostly (2 or)3-6, rarely more, usually free or connate at base only, sometimes partly united into a tube, caducous or persistent, rarely accrescent. Petals 3-8, rarely more, often isomerous and alternating with sepals, free, imbricate or valvate, rarely contorted, similar to sepals or not, sometimes with a fleshy adaxial basal scale, or petals absent. Disk present, entire, lobed, or comprised of free or connate disk glands, these extrastaminal, interstaminal, or intrastaminal, or extragynoecial, or disk absent.

萼片覆瓦状或镊合状排列，很少佛焰苞，几乎(2或者)3-6，很少更多，通常离生或者只是基部合生，花瓣3-8，很少更多，通常与萼片同质并且互生，分离，覆瓦状或镊合状排列，很少旋转状，与萼片相似或不相似，有时在近轴基部有一个肉质的鳞片，或花瓣无。

利用直接在镊尖施加外力使其张开的方法可简便、迅速地测量反向夹持镊的作用力

We constructed a holographic-optical-tweezers-based line traps system and established a theoretical model for the line trap.

在本研究中，我们建构一套线形捕捉全像雷射镊夹系统，并建立模型分析线型雷射镊夹捕捉微粒子的捕捉力。

After the emergence of optical tweezers, using it to study the optical rotation get people\'s attention, it can operate particle on the angle.

光镊出现后，利用光镊来研究光致旋转得到了人们的关注。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
