光的微粒理论

Correlation between spin angular momentum s and background angular momentums of planets;2. In the paper the principle of optical rotation due to the transfer of spin angular momentum from light to particles was discussed by analyzing the interaction between the beam of light and birefringent crystal particles, and then an optical tweezers was formed on nanometer optical tweezers system with a linearly polarized light beam (He-Ne laser 633 nm, 10 mW).

从理论上分析了偏振光束与双折射晶体粒子的相互作用过程，讨论了由于光束自旋角动量向晶体粒子的传递所导致的光致旋转效应的原理，并在纳米光镊装置上利用线偏振He Ne激光器(633 nm，10 mW)形成了光镊光阱，利用1/4波片来改变光镊光束的偏振状态，在不同的椭圆偏振状态下实现了直径约为几微米的CaCO3 晶体微粒的捕获和光致转动。

Our aim was to introduce another theory of light, different from the corpuscular one, but also attempting to explain the same domain of facts.

我们当时的目的是要介绍另一个光的理论，这个理论与微粒说不同，但也想做到能解释同样多的现象。

One concept was the corpuscular theory, which envisioned light as a stream, or flow, of small particles.

一个概念就是微粒子理论，把光想象为溪流，或微小粒子的流动。

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。

In the meanwhile, the TS characteristics of a scattering particle and their relationship are studied when it is passing through the scattering area, In addition to this, the distribution function of particles' shape is defenited in terms of math's method and a new method is putout of which the distribution of particles' shape is captured in according to the power spectrum and spectral distribution characterist of light scattering and finally, the utility of the perturbation ameliorating method and the effect of the particles' shape is modified, so far, the accuracy of measurement of the particles' size is improved effectively.

对此，本文在以Mie散射理论为原理，依据前向接收器接收的前向散射光信息以获取微粒大小信息的测量基础上，对微粒穿越光敏区时的时域与空域的特征以及相关性开展了研究，从数学上定义了微粒的形体分布函数，提出了一种依据光散射功率潜和频谱分布特征来获取微粒形体分布信息的方法，完善了微扰修正理论的应用性，有效地改善了形体的影响问题，从而可提高微粒粒度分布测量结果的准确性。

Theoretical analyze the principle of the optical rotation of the crystal particles by angular momentum of beam spin.

从理论上分析了光束自旋角动量使晶体微粒光致旋转的原理。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
