光线的

Unlike rendering solid objects with well-defined boundaries, volumetric shading determines how light passes through an object, not just how it bounces off the object.

和渲染固态实心的物体不同的是，体积渲染没有一个清晰明确的渲染边界。体积材质节点测算光线是如何穿过物体起作用而不是测算光线在物体表面的反射。

The computational flow of light propagation and the key techniques of visualization are presented. An optical system was employed to verify the correctness and feasibility of quaternion method in the calculation of beam propagation, and the pincushion distortion caused by the optical system was successfully simulated.

通过对某光学系统的仿真分析，成功仿真出图像经过光学系统产生的枕形畸变，证明四元数方法在光线传输运算中的正确性与可行性，为复杂光学系统的空间光线传输计算提供了另一种方法。

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。

It will decrease when the pointing angle increases,and vice versa.By giving a pixel size of 20 μm for a detector,an orbit altitude of 600 km and a beam deflexion angle low than 30° for the imaging spectrometer, the effective focal length of the telescope was calculated(400,470 or 435 mm),and the relation curves between the relative ratios of ground resolution and the beam deflexions were presented.

给定成像光谱仪探测器像元尺寸为20 μm，飞行轨道高度为600 km，光线摆角≤30°，以星下点、最大摆角和整个运动补偿段地面分辨率中值为30 m为依据来计算望远系统的焦距，求得望远系统焦距为400、470、435 mm，并给出了此时的地面分辨率相对比值与光线摆角的关系曲线。

The pupil diameter of different diopters changes greatly under different rays, and it is a very important parameter to measure the pupil diameter in different diopter under different rays before the refractive surgery.

不同屈光度在不同光线下瞳孔直径有很大的变化；不同屈光度在不同光线下的瞳孔直径是屈光手术前评估的一个重要参数。

It was the light. It was still the gray-green light of a cloudy day in the forest, but it was clearer somehow.

是光线。虽然依旧是阴天森林里的那种灰绿色的光线，但不知怎么的，的确明亮一些了。

In this paper, an equation descriping Proca light traveling in gravitional field is derived.

本文在导出Proca光线在引力场中的传播方程后，以球对称引力场以及平面引力波分别作为静态和动态引力场的例子，计算了有质量光子对应的光线偏折与频移。

They were in fact purple-blue and when the light went inside they turned more blue and had a stronger color - the people had white masks on and goggles standing away from them when the light was going inside the crystals.

他们其实紫蓝色，当光线走了进去，他们把更多的蓝光和有较强的颜色-人民已经在白色口罩和护目镜站在离他们当光线被发现的晶体去。

The principle of an optical microscope is quite simple; however, the resolving power of an optical microscope is limited by the wavelength of the light employed, being greater when the light source is shorter wavelength.

光学显微镜的工作原理其实非常简单，然而，光学显微镜的分解力受到其所使用光线波长的限制，光线波长越短，其分解力就越大。

光学显微镜的工作原理其实相当简单，然而，光学显微镜的分解力受到其所使用光线波长的限制，光线波长越短，其分解力越大。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
