From the perspective of matter wave in quantum mechanics, this paper, by describing the wave function of microcosmic particle and using probability wave, derives the distributive regularity of light intensity of the single slit diffraction and circular aperture diffraction.

光具有波粒二象性，从量子力学的物质波出发，利用描述微观粒子的波函数，采用几率波的方法，导出光的单缝衍射和圆孔衍射的光强分布规律，所得结果与波动光学中用惠更新－菲涅耳原理得到的结果一致。

Recent progress on surface modifications of TiO2 doped by metal cation and metalloid anion has been summarized,based on the findings reported in the present literatures.

早期的研究主要集中在悬浮体系即TIO：粉末上，但目前悬浮相TIO：光催化剂在水中易凝聚、易失活、且使光的穿透力受阻，尤其是处理后的光催化剂分离与回收的难题已成为该项技术能否工业化的关键。

What could make their skin shine moon-bright like that, or their white-gold hair fan out behind them without wind..

A spatial distribution of diffuse reflectance produced by obliquely incident light is not centered about the point of light entry.

倾斜入射的光所产生的漫反射的空间分布，其中心与光的入射点存在一个偏差，这个偏差与组织的吸收系数和有效消光系数有直接的关系。

I dare to say he will use up all the money, because he is a peron who will use up the money the moment he get it.

我敢说不出几天他就会把钱花光，因为他是个有钱就要花光的人。

Due to the phototaxis of pests, fluorescent lamp, blue lamp or ultraviolet lamp can be used as bait, equipped with a high voltage （3000-4500V）and low current（5-10mA electrified wire netting around the lamp tube.

根据害虫趋光的习性，利用日光灯、蓝光灯或紫外线灯作引诱源，在灯管外围装置高电压（3000-4500V）、低电流

Secondly, the visibility of interference fringes is increased by raising reflectivity of uppersurface of glass plate and convex of plane convex lens.

垂直入射平行光I经多次反射和折射后，形成光束Ⅲ和Ⅵ，二者迭加而产生干涉，即所谓透射光的干涉。

Because the optical system of optical characteristics and the nature of the launch of the optical microscope is not the true meaning of the linear shift-invariant systems, the PSF is usually perpendicular to the optical axis in the xy plane was the distribution of radial symmetry, but the direction along the z axis significant expansion.

因为光学系统的特点和发射光的性质决定了光学显微镜不是真正意义上的线性移不变系统，所以PSF通常在垂直于光轴的x-y平面上呈径向对称分布，但沿z光轴方向具有明显的扩展。

The reflection of the LO mode, RLO, and its ratio, RLO/RTO, with the reflection RTO of the LO mode increase with increasing angle of incidence. In the case of the polarized incident light,ωLO is a function of angle of incidence and polarization state of the incident.

在45°入射角附近，ωLO几乎与入射光的偏振方向无关；在这个临近角45°两侧，ωLO和入射光的偏振方向的关系呈现相反趋势：当入射角小于45°，ωLO随着入射光极化仰角θ的增大而减小，当入射角大于45°，ωLO随着极化仰角θ的增大而增大。

Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

然后用二能级模型解释了单、双、三光子激发原理，在理论上推导出了单、双、三光子吸收诱导荧光强度与脉冲强度以及脉冲作用时间的关系，并进一步研究了入射光时间分布分别为矩形、高斯型、双曲正割型时激发溶解在氯仿溶液中的C22H22N4O样品所产生的荧光峰值光强，结果表明激发光的时间分布对双、三光子荧光峰值强度的影响比对单光子的影响要大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
