This paper presents a new rendering algorithm by the contrast between the Flat method, Gouraud method and Phong method, through which the color of each pixel can be figured out under the lighting model after the coordinates and normal of every corresponding point on the 3D-object surface have been calculated from the pixels in the range where the 3D-object is projected onto the photo, in order to provide each pixel a real color and get an image with strongest feeling of reality.

本文在对比研究了真实感图形生成中传统的Flat，Gouraud，Phong等明暗渲染方法后，提出了一种新的明暗渲染方法。在图像平面三维物体的投影范围内，由图像的像素坐标求出物体模型对应点的三维坐标及其法矢，然后对每个像素点根据光照模型来计算其明暗度。这种方法能够最大可能的保证图像中每一像素点明暗度的真实性，从而使所生成的真实感图像更加逼真。

The light sources of edge-type LED backlight units in small/medium displays are an array of LEDs located inside a lamp reflector and near the incidence plane of a light guide plate.

中小尺寸LED背光模组发光源为置於侧边之复数个LED点光源，其所面临的固有问题在於入光侧容易产生明暗不均，亦即导光板在靠近LED光源处会出现过之投灯亮带而在LED之间则容易形成较暗之暗区。

The typical structural characteristics of oil cells include, presence of a tripartite cell wall, in which the outer and inner layers are cellulose, the middle layer is a suberin layer lamellated; presence of a cupule attaching the oil vacuole to the wall; presence of plasmodesmata occurring in wall protuberances, which is coursed by the suberin layer.

成熟油细胞结构的典型特征是：具有三层暗明暗相间的细胞壁，内外两层是纤维素壁层，电子不透明，中间一层是电子透明的木栓质化壁层，由明暗相间的片层结构组成；细胞腔被油囊充满，它由一个细胞壁向内突起的杯形构造连接于细胞壁上：胞间连丝发生于由木栓质化壁层形成的一个向内的突起中。

This paper discussed an important step in volume rendering—— shading , using a fast algorithm based on a unit sphere segmentation.

针对体绘制的一个重要环节——明暗度的处理，提出了一种基于球面三角化的快速算法，其速度较传统的明暗度处理方法快近 2倍，同时大大节省了中间数据的存储量，有利于在微机上实现。

Caliche on gravel, as an indicator of variation of sedimentary environment, records relatively complete information on environment and climate.

砾石钙膜作为一种反映环境变化的沉积物标志，记录了比较完整的环境和气候信息，其实物的直接表现形式就是沉积了明暗相间的纹层，而形成明暗纹层的主要原因是受沉积时碳酸盐的纯度和结晶物的粒度以及杂质等的影响。

When scanning, from light transmitter beams shines on the bar code on the basis of the photoelectric detector from bar code on the binvalidation of the reflected light intensity to respond to that, when scanning a white spot sweep to the surface or in two in the space between the black line, the reflection of light intensity, high current output a detector; when the scan-to-black lines, reflected light, detector output UN-effectual, on the basis of narrow-striped width or length of time made in response to changes in light and shade with bar code and converted to a little different current signal, after a post to the bezze codec.

扫描时，从平发射器发不入的平束照在条码上时，平电检测器根据平束从条形码上不直射返来的平不不弱度息不入回答，当扫描平不背扫到白纸背上或处于两条暗线之间的空缺处时，不直射平不不弱，检测器输不入一个不小电流；当扫描至暗线条洋时，不直射平不弱，检测器输不入小电流，并根据暗线宽或广息不入工夫不幼短差别的反响，随着条形码明暗的改变变化为人小差别的电流暗记，经过放不小后运输到泽码器洋去。
