查询词典 reflection of light

An oxygen-bubble and white-light speckle velocimetry method is presented.Instead ofpulsed laser and commonly used particle,a sheet like-bubble mass generated from anade wire byeletrolysing water is used as particle tracer,a white light flash set controlled by digital time delaycircuit is used as double pulsed light source,and 2-D velocity distribution in a sectional planewithin flow field can be obtained without using light sheet technique.

提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。

In order to obtain symmetry and parallel polarized light,the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle,an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams.

为了获得对称且平行分束的偏振光，对双Wollaston棱镜进行了修正，在获得大分束角的对称偏振光后，配合普通玻璃三棱镜，使对称分束光变成平行分束光，通过改变三棱镜与双Wollaston棱镜间的距离来改变平行光的剪切距离。

However, the image-retrieving environment is so complicated, such like from a nature object to a variety of objects, from a light environment to a dark environment, or from a nature light to a daylight in office, the properties of objects, and the varieties of light sources and light intensities. These complex external image-retrieving environments let users can not get an accordant image quality. Such under a tungsten lamp, the image appears yellowish and reddish; under daylight in office, the image becomes greenish and bluish.

CCD Camera面对的是复杂的取像环境，从自然景物到各式各样的景物，从光亮环境到灰暗环境，或从自然光到办公室日光灯、景物的特性、光源的种类及光线的强弱，这些外在复杂的取像条件及变因往往让使用者无法得到相当一致的影像品质，如在钨丝灯下拍摄的影像，将产生偏黄、偏红效果的影像；在办公室的日光灯下将产生偏绿、偏蓝效果的影像。

According to the international standard ISO7027,we can know that the measurement of turbidity mainly use the optical turbidimeter measurement,it contains the scattering-light method and transmitted-light method. The scattering-light method has application in measurement for low turbidity water and also can used in high turbidity water.On the other hand,the transmitted-light method is more suitable for high turbidity measurement.

根据国际标准ISO7027可知，现今测量水的浊度主要以光学浊度仪测量法为主，主要包括散射光法和透射光法两种，散射光法主要用于测量低浊度水，但也可用于高浊度水的测量；而透射光法更适合于测量高浊度水。

Based on the Mie scattering theory, a formula to calculate the scattered light flux in a certain solid angle under the condition of polarized light input is derived form the formula for calculating scattered light intensity. The results are compared with the condition illuminated by a unpolarized light.

在Mie散射理论基础上，由单分散射的光强表达式导出在偏振光的入射条件下一定立体角内的散射光通量的表达式，并与自然光入射作比较。

There is no need to light anight light on alight night like tonight.for abright night light is just like aslight light.

像今夜如许明亮的夜晚，就不需要点一盏夜灯，因为明亮的夜灯也会变得微弱。

Armillary light source could provide light intensity from surrounding to center, and the intensity of light changed gradually. The intensity of light was the same from the point of the center to the same circumference line of the surrounding.

环行光源可以提供从四周到中央的光亮度逐渐移行，从中央点到外周的同一圆周线上光强度是一样的，色度值也基本相同。

A laser 3D body scanning system based on light stripe method was presented,which can realize body contour automatic scanning from top to bottom and forming a circinal stripe on body surface with four semiconductor laser linear light sources.Light stripe image is received from eight image CCD cameras located on the two sides of linear light sources.
