point light source meaning in Chinese
点光源
Examples
- The axd series is a group of high - brightness point light sources having a continuous spectrum similar to that of the sunlight
短弧氙灯:该产品是一种高亮度的点光源，具有像阳光一样的连续光谱。 - A pigtail with laser coupling lenses as a point light source of interferometer is designed . it can be separately used to the body of interferometer
在实验系统中，设计并实现了带耦合系统的单模光纤导光系统，使光源和干涉仪主体的可以分离。 - Being a point light source the light rays direction on an object surface is given by the line joining the point light source and the point on the surface of the object itself
作为一个点光源，光线在一个物体表面上的发射方向使用光源所在点和物体表面点之间的连线来确定的。 - The form of the psf has been deduced according to the fresnel diffraction , and it has been analyzed that the frings density of the psf depends on the axicon ' s refracting angle and the distance l between the point light source to lens l2
利用菲涅耳衍射理论，推导出相干光照明下无衍射系统的点扩散函数( psf )的形式，并分析出点扩散函数的条纹疏密与锥镜的夹角和点光源的位置有关。 - After the comparing the simulation results with the theoretic results under the three followed condition : a point light source on the parabola reflector focus , a point light on the ellipsoid reflector focus and a point light source before the parabola reflector focus , a conclusion is gotten that the two results are generally accordant , the accuracy of the simulation software reach the engineering requirements and the computational simulation software of photometric characteristics of headlamp of motor vehicles can guide the design of the headlamp reflectors
比较了点光源位于抛物面反射器和椭球面反射器焦点的情况和点光源偏离抛物面焦点的情况下照度的理论计算结果和采用本文的照度仿真计算结果，其仿真计算结果和理论计算结果基本相符，能满足工程上的要求，说明仿真计算软件对前照灯的反射镜的设计具有很好的指导意义。
