光线

Light resulted in precocious puberty is one of the important reasons.

光线过度。光线也是导致性早熟的重要原因之一。

Based on the measured refractive index distribution curve, according as the theoretical model of light transmission in the GRIN medium, using quadrivalent Runger-Kutta method to carry out the light tracking, by this means the mainly imaging character index of themicro-lens such as foci, longitudinal and transverse spherical aberrations aberration etc is calculated.i.

According to the spatial coherence, a fast algorithm for ray tracing is proposed for rendering implicit surfaces.

根据光线的空间相关性，本文提出了一种基于图像空间剖分的隐式曲面快速光线跟踪算法。

When the light ray refracts at the interface between a traditional positive-refractive-index material and a novel NIM, negative refraction occurs where the refracted ray and the incident ray lie on the same side of the normal line, which means that the emergence of NIMs changes the traditional propagating laws and the basic imaging properties of lenses.

当光波从传统的正折射率介质入射到负折射介质的界面时将发生折射光线与入射光线位于界面法线的同侧的负折射现象。

Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。

In the world, most of the work is using the ray casting method for such a hybrid rendering. This is because the sample point of geometric objects can be conveniently inserted into the sequence of points in the volume along a ray line.

国际上关于这方面的工作很多，但基本上是运用光线投射方法进行混合成象，因为在每条成象光线的数据样点序列中，便于插入几何形体的样点。

One-click fixes allow users to quickly enhance videos and photos taken in less-than-ideal situations, such as in poorly lit rooms or while moving, aiming to remove poor lighting, shakiness and inaccurate white balance.

单次点击式修正使用户能够快速提高视频和照片采取低於理想的情况下，例如在光线暗淡的房间或在移动中，旨在消除光线不好，颤抖和不准确的白平衡。

However, when light travels from air to snow, some light is sent back, or reflected.

但是，当光线从空气前往雪，一些光线被遣送回国，或反映。

Refraction: The change of direction of a light ray or energy wave from a straight line as it passes obliquely from one medium to another in which its velocity is different.

折射：当光线或能量波倾斜着穿过一种媒介到另一种媒介时，由于光线在两种媒介中的传播速度不同，导致其传播方向发生偏转。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
