光子

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。

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。

This may be used to measure the quark structure of photon.

由此我们可推知，HERA分解光子过程中的双喷注产生提供了检验QCD理论和测量光子的部分子结构的机会。

It is suggested that the nature of Talbot serf-imaging is the recordation and reappearance for periodic space information of object by photons.

与此同时，提出了塔尔博特效应实际上是光子对周期性空间信息的记忆与再现的过程，从而对光子在光传播过程中携带空间信息产生了一定认识。

In addition, broad-linewidth reflection bandstop filter with one-layer grating structure is designed by use of optimization technology for diffractive optical elements and rigorous grating diffractive theory. Finally, rigorous theory is used to analyze photonic crystals for their subwavelength periodic structures.

根据二维光子晶体的结构特点，提出光栅层模型，使二维结构退化为一维结构，从而大大简化了计算过程，提高了计算速度，并编制了计算程序，详细讨论了几类二维光子晶体的禁带特征。

This procedure can be applied to real photonic devices. For example, an optical refractometer or a chemical sensor can be designed by replacing the intermixing material by the medium to be measured.

这种具有光栅结构的手徵性光子系统能够提供另一种可能性的方法建构实际的光子装置，如生物/化学感测器或折射计。

In nitrogen,carbonmonoxide and hydrogen we obtained two-or three-photon resonantly enhanced third harmonicgenerations through many band systems.

在N2，CO和H2中我们得到了与多个带系双光子共振以及三光子共振的三次谐波。

On the basis of wavelength distribution of the continuum emission,we suggested that atom Al resonantly absorbing continuum radiation was absorbs energy by atom solid,which consists o...

我们认为：Al原子吸收能量的主要机制是原子实吸收连续辐射光子，原子实吸收光子的方式是与价电子构成极性振子对连续辐射共振吸收。

Our group started the experimental test of the photon rest mass in 2000, and presented a scheme of the modulation method with the precise torsion balance.

我们实验室于2000年开始进行光子静止质量的实验检验，并提出了扭秤调制法检验光子静止质量的实验方案。

Whether the rest mass of the photon is zero or not hence became one of the fundamental problems confronted by many physicists.

恒定光速暗含了传播电磁波的媒介——光子的静止质量必须为零的假设，而光子静止质量是否为零也就成为物理学家们一直希望能够正面回答的基本问题之一。
