The effectiveness of hematin and protoporphyrin IX as photosensitizes in singlet oxygen(1O2)generation was determined and at the same time the influence of different light wavelength on them was studied.

研究了肌红蛋白的组成成分血红素和原卟啉的光敏能力，同时分析了不同波长光的照射下血红素和原卟啉对猪肉脂肪氧化的影响。

Fresnel thought that the light vibration is one continuous medium- by condition mechanical elastic vibration, he supplemented the huygens' principle by the Young interference principle in 1835, from this has had the Huygens - Fresnel principle which is familiar by people, with this principle can either completely explain the light straight line dissemination,or can discuss the diffraction phenomenon,and it becomes a important principle in the wave optics.

菲涅耳认为光振动是一种连续介质-以态的机械弹性振动，他于1835年以杨氏干涉原理补充了惠更斯原理，由此产生了今天人们所熟知的惠更斯-菲涅耳原理，用这个原理既能圆满地解释光的直线传播，也能讨论衍射现象，成为波动光学中的重要原理。

It was proved that the prism could replace the prism which was only made of iceland crystal in general.

其中，图1为一种单一棱镜式的超高透激光偏光棱镜，其出射光束与入射光束不同向，给使用带来不便；图1是两只单一棱镜的组合，其作用是实现出射光和入射光的同向，但需要较多的冰洲石晶体材料。

This image has travelled a great distance, and because the intensity of light falls off as the square of the distance, the loss of light is great .

这种图象已移动了很长一段距离，并且由于光的强度随距离的平方而减弱，所以光的损耗是非常大的。

Saturation refers to the purity of the color, if a mass spectrum in a light reflectance high, and on other band of light in a very low reflectivity or not, this color purity.

饱和度是指颜色的纯度，如果一物体对光谱中某一波段光的反射率高，而对其他波段光的反射率很低或没有，则此色的纯度就高。

Their hunting is done with a lot of guess work thrown in, that probably why most Siamese cats are pampered house cats it was too hard to make a living as a mouser.

从猫寻找在晚上漫游他们的眼睛被创造允许同样多光的事尽可能，他们的视网膜用帮助进入更多光的一部反射性影片涂。

This paper gives a new method for measuring the concentration of pulp.The laser and optical fibre measurement is based on the back-scattered theory and the principle of reflection and refraction of light.

根据光的后向散射理论，利用光的反射和折射原理，本文提出了一种新的在线测量纸浆浓度的方法——激光光纤测量法。

Ideally, the parallel rays which reach the pupil at different positions in a meridian will cause various sensitivity responses and can be fitted by a 2nd order parabolic curve.

此曲线的峰值点的位置即是通过水晶体后和光杆细胞轴向平行的入射光的入射位置。

The photo techniques are widely used in the criminology techniques researching areas. The telling of the light is first routine steps of either the field perambulation or the testing of material evidences.

光技术的应用在刑事科学技术领域极为广泛，无论是现场勘查，还是物证检验，光的检测是例行的第一步，它具有灵敏度高，不损害检材的特点。

Because of the collective modulation of the periodic dielectric distribution to the incident electromagnetic waves, the directions of the group velocity and the phase velocity can be opposite, a photonic crystal slab can work as a negative refractive-index material.

由于介电函数的周期性分布对入射光的调制作用，使得特定频率区域的入射光在光子晶体中传播时的群速度方向和相速度方向相反，因而使得光子晶体平板表现出负折射特性。

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。
