His postulation of the photon (a "particle" of light) and the photoelectric effect — which was described in his first great paper of 1905 and won him the Nobel Prize in 1921 — gave us scores of everyday applications.

他关于光子和光电效应的假设——其论述见于他1905年的第一篇重要论文，该假设使他获得了1921年的诺贝尔奖——为我们提供了几十种日常应用。

Also, optical dipole potential and photon scattering rate of the trapped cold atoms were calculated.

同时还计算了光学双阱囚禁冷原子的光学偶极势和光子散射速率。

This is because the scattered photon energy flux from the atmosphere scattering near the source preponderate over the absorption.

这是由於源附近大气对光子散射到达探测点的注量超过大气对光子的吸收所致。

By the means of experiments and numerical simulations, it is verified that speckles can be formed when nanofluids are illuminated by laser beam. First, clear speckles are formed by illuminating static nanofluids containing proper volume fraction of nanoparticles. Then, classic-scattering-model and photon-nanoparticle-collision-model are respectively established based on the wave-particle duality of light. The formation of speckles with nanofluids is simulated respectively on these two models, and the formation mechanism of speckles is figured out.

In addition, the two-photon absorption cross section σ non-linearly increased with a ratio of 1∶2.8∶3.7, which is near to the ratio of the square of branching number n2 (1∶2.25∶4), indicating a remarkable cooperative enhancement of σ in the multi-branched pyrazine derivatives.

另外， 从双支到四支结构，双光子吸收截面σ按照1∶2.8∶3.7的比例增加，接近于支链数目的平方之比(1∶2.25∶4)，表明多支结构的双光子吸收存在显著的增强效应，其中四支结构的σ值为1007 GM。
