光源

Several firms are getting ready to tap into this underserved market.

几个公司已经准备进入这个光源服务市场。

PSD7151W with innovative structural design, is a suitable infrared outside the network security uniform ball and cover with the rotating movement, for the first time a multi-way to extend the life of bearings, infrared lights up and down together with the Yuntai the right and left rotation, make full use of light source, greatly enhance the user's viewing angle, no dead ends to facilitate monitoring and return to the default preset inspection points.

PSD7151W 以创新的结构设计，是一款适合于外安防的红外网络匀速球，球罩与机芯一起旋转，首次采用多轴承方式延长寿命，红外灯随云台一起上下、左右旋转，充分利用光源，大大提升使用者的可视角度，监控便利无死角，且可预设预置点来回巡视。

Then, we present an efficient sampling algorithm on the unit sphere, and the generated point distribution can match the SRBF representation. We are capable of creating images with multiple measured BRDFs under global illumination.

此外，根据球面射基底函的表现形式，我们也提出一种有效的重要性采样方法，其产生出的采样分布可以合球面射基底函所描述的资分布，此方法可以在全域光源照射的环境下，有效地绘制包含多种复杂材质的场景影像。

Where for each of the i light sources, is the unit vector pointing toward the light, is the light color, and N is the unit normal of the surface.

简单的说，diffuse函数就是统计场景中所有光源在物体表面上某一点产生的颜色值

First, we use the universal skin-color map to detect the face regions, which can ensure sufficient adaptability to ambient lighting conditions.

首先，我们使用通用肤色图侦测脸部区域，以确保在周遭光源条件变化时，仍有足够的适应性。

There is, unquestionably, multiple sources of light in addition to the Sun.

毫无疑问，这来自除太阳之外的多个光源。

Hiht efficiency energy-saving:Adopt high efficiency gas discharge sources with the function of energy saving,ling service life which reaches 1500 hours,especially for use as illumination in unwatched large area.

高效节能：选用高效气体放电光源，节能、寿命长、灯泡使用寿命高达15000小时以上。特别适合户外大面积无人看守照明。

Shanghai Yahong Electrical Lighting Co., Ltd is the professional manufacturer of High Pressure Sodium Lamp, Metal Halide Lamp, Fishing lamp, color Metal Halide lamp, Uni-form Pulse Start Metal Halide Lamp, Pulse Start Metal Halide Lamp and Mercury Vapor Lamp etc, the company locates in Shanghai, it is very convenient for shipping.

上海亚鸿照明电器有限公司是专业生产高压钠灯，金属卤化物灯，捕鱼集鱼灯和高压汞灯等高强气体放电灯光源的生产基地。公司创建于1997年，坐落在上海市宝山区，直达上海港，交通极为便利。

Objective To investigate whether disability glare happen or not in myopia under the low intensity of veiling glare source.

目的 探讨在低强度幕罩眩光源下近视眼是否存在失能眩光。

The influence of disability glare is decided by the Equivalent Veiling Luminance and average road luminance.

失能眩光是由于眩光源在人眼屈光介质内形成散射而形成的，可以通过等效光幕亮度和路面平均亮度来确定失能眩光的影响大小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
