光源

In this paper, we present an analysis of quotient image method from the view of image linear subspace, and point out its main deficien- cies: 1 inaccurate assumption of ideal class of object, 2 3-d subspace doesnt suffix to represent all images of an object under varying illuminations.

在本文中，我们从图像子空间的角度对商图像方法进行了分析，理论分析和实验表明，这种方法存在的主要缺点有：1不准确的理想类假设；2简单的三维点光源模型无法很好地近似任意光照情况。

The invention discloses a vehicle speed matching method based on linear array CCD image, including the following steps that: two linear array CCD video cameras are respectively arranged on two sections positioned on a road at intervals; both linear array CCD video cameras face downwards and are provided with infrared ray laser source; the frame rate of each CCD video camera is more than 1,000 frames per second, and the resolution is more than 1,024 lines; correlation matching computation of the image sequences obtained by both linear array CCD video cameras is carried out to obtain the time difference of the same object in two image sequences; finally, by means of the time difference and the distance between both cameras, the driving speed of an object vehicle can be obtained according to the velocity formula V=s/t.

本发明公开了一种基于线阵CCD图像的车辆速度匹配方法，该方法在道路相距一定距离的两个断面上分别安装两个线阵CCD摄像机，两个线阵CCD摄像机指向垂直向下，线阵CCD摄像机上配有红外线激光源，线阵CCD摄像机的帧速率大于1000帧/秒，分辨率大于1024线；对两个线阵CCD摄像机得到的图像序列进行相关匹配计算，从而获得同一个目标在两个图像序列中的时间差，利用该时间差和两个摄像机的距离，根据速度公式V＝s/t即可以得到目标车辆的行进速度。

It is an new technology to use synchrotron radiation lithograph for making large scale integral circuit.

在进行大规模集成电路光刻时，采用同步辐射光源是一项新技术。

When Lloyd's mirror interference is combined with grating diffraction the fringes for different colors produced by white light source can be coincident, thus the white and black fringes will be observed.

把劳埃镜干涉和光栅衍射结合起来，有可能使白光源产生的不同颜色的条纹彼此重合，从而能观察到清晰的黑白条纹。

The carriage is supported beneath contact glass and movable in a direction normal to a longitudinal axis of the line light source.

该托架支撑在玻璃罩下方，并可以在与线光源的纵向方向垂直的方向上移动。

I think Haiwang regarded the land of the lotus and itself; He abandoned the details of lotus and focused on the object-oriented structure and only organic color contrast (such as the use of a lot of black); He considered only Light color with the seasons and the geometric structure of the landscape. It's different from the only source style and the natural tendency of Impressionism . It has more spirits with the traditional Chinese culture and the aesthetic value.

我想这与李海旺把荷花与生长它的大地联系起来描绘有关系；与他舍弃了荷花的细节，只注重对象的有机的结构和色彩的单纯对比有关系；也与他只考虑光色的季节和几何化的风景构造，也不同于印象派只重光源色的自然主义倾向而获得了与中国传统文化相通的审美价值。

That part of a luminaire designed to control the spatial distribution of the luminous flux of the lamp.

灯具的一部分，用以控制光源光通量的空间分布

Luminous flux is in relation to radiant intensity and wavelength.

光通量与光源的辐射强度有关，还与波长有关。

The luminous flux per unit area at any point on a surface exposed to incident light.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
