光点

This was also capable of reflecting economic and political aspects of the society at that time. President Lin Chun-shin pointed out that judged from Western art history, the painting before the eighteenth century would clearly delineate an object but there was a lack of the element of light. In the nineteenth century, Impressionist would raise the brightness of a painting through pointillism using three primary colors and come up with a feeling of light. Despite of the fact Vincent van Gogh's works had been systematically manipulated by painting dealers on the art market, the real reason for his paintings to excel after 100 years were his capability to apply pointillism techniques with distortion to express feelings, which could not be done by other painters.

林俊兴董事长表示，以艺术史的角度来看，十八世纪以前的绘画是将物体清楚描绘出来，但却缺乏光的元素，而十九世纪的印象派画家，却能运用三原色的点描提高画作中的明度，画出光的感觉；虽然梵谷的作品被画商有系统地於艺术市场推波助澜，但真正使其作品百年后脱颖而出的理由，是梵谷能把点描技法加上扭曲，表现出其他画家无法绘出的情绪。

依据基尔霍夫衍射理论，利用幂级数展开的方法推导出旁轴条件下高斯光束双缝衍射的近似光强计算公式，并通过数值计算对双缝衍射的基本特性进行了讨论，得出了与其他文献一致的结论，得出了高斯光束下的双缝衍射极小值点比平行光束双缝衍射的极小值点向外移，观察屏中心光能变小；光强分布可由激光斑在衍射屏处的参数调制的结论。

现代中国画家从我国舞台美术、民间美术和西方现代主义绘画中吸取有益的因素，采用点光、色彩变调所呈现的有层次、有变化的光，来突破传统的平面光，并使这种光成为画面灵动活泼的语言。

The following central point within a small local region of current tracing point can be obtained based on the influence of neighboring points as well as the smoothness and fairness principle. Finally, a sequential of central points can be traced out efficiently without any iteration and a parametric curve can be reconstructed by interpolating the central points.

该方法仅从当前跟踪点的邻近点集与曲线重建光顺准则出发，无须迭代，可快速、有效地跟踪得到无序点集的一个中轴点列，最后再由此点列拟合出参数曲线。

Among the four species of ground cover, the light saturation point and light compensated point of Ardisia japonica was the highest, and the value was 645 and 202 u mol/m2s, respectively, while the light compensated poin of Belamcanda chinense was the lowest.

四种地被植物中，紫金牛的光饱和点与补偿点最高，分别为645与202μmol／m~2s，金叶过路黄、多花筋骨草与射干依次减小，光补偿点以射干为最低。

The photosynthetic rate is the highest at 40μmol/m^2s. The light intensity for photosynthesis of Batrachospermum longipedicellatum. is saturated light intensity. The light compensation points increase with the rise of water temperature. They are 4.5, 5, 5.6, 6 and 7μmol/m^2s at 5℃, 10℃, 15℃, 20℃ and 15℃ respectively.

长柄串珠藻的光补偿点随温度的升高而升高，5℃、10℃、15℃、20℃和25℃的光补偿点分别为4.5μmol/平方公尺s、5μmol/平方公尺s、5.6μmol/平方公尺s、6μmol/平方公尺s和7μmol/平方公尺s。

We can acquire the locutions of points with the same principle stress direction and the principle stress difference through the photoelastic experiments These data are the important parameters in photoelastic stress analysis.

我们可以透过光弹实验得到具相同主应力方向点的轨迹，与相同主应力差值点之轨迹，此两组数据为光弹应力分析中之重要参数。

The theoretical results show that,compared to the source spectrum,the normalized spectrum in some points of the diffracted field is blueshifted,and in the other points of the diffracted field the normalized spectrum is redshifted.

理论研究结果表明：部分相干光谱经单缝衍射后，在衍射光场的某些点，光谱相对于光源的光谱往短波方向移动，即为蓝移；而在衍射光场的另一些点，光谱呈现红移。

I normally use quite a lot of light sources; I place them so I can highlight details of the scene. In this image I have used 13 lights: 4 omni lights as ambient lighting, 2 to highlight the form of the engine, 3 spotlights to highlight the back of the engine, 3 highlight to stress the specular and the greasy effect on the shell, a spotlight behind the snail neck for the sub surface scattering, in addition to the sun with area shade and the sky with a HDRI with an atmosphere similar to the photograph of the road for the global lighting I have used a surface with an asphalt texture for the floor and the yellow lines only to be reflected on the engine and to add some radiosity to the snail body and shine.

通常我使用很多的光源，我到处放置它们，这样我才能照到足够多的细节，在这幅图里我使用了13盏灯，4 盏点光源作为环境光，2盏来照亮引擎的形状，三盏聚光灯用来照亮引擎的背面，三盏来强调蜗牛壳的高光及油腻的感觉，有一盏蜗牛脖子背后的灯光来表现3S半透明效果，另外还有一盏太阳光来获得各个区域的阴影，以及一个赋予了HDRI贴图的sky，来作为全局光，我使用了一种沥青材质作为地面材质，并让引擎能反射地面上的黄色带子，并为蜗牛身体与光射线增加了一些radiosity，以取得得与背景类似的灯光环境。
