光源

This was where objects were placed on light sensitive paper or materials and exposed to light, fixing an indexical trace of the subject matter.

我总是喜欢将之比喻成一种早期制作影像的格式「光影图像」，这是一种在感光相纸或感光材质与光源之间，对物体进行曝光之后再进行校准、整修影像的方式。

The parameter of beam positions at HLS 200 MeV LINAC is very important to injection efficiency.A new strip-line beam position monitor system was designed recently,which is not interceptive to beam,qualified in precision and easy to digitalize the results.

合肥光源(Hefei Light Source，HLS)200 MeV直线加速器的束流横向位置是一个重要的运行参数，直接决定注入的效率，为此新开发了一种非拦截型、高精度、易于将测量结果数字化的条带电极束流位置测量系统(beam position monitor， BPM)，该系统由条带电极和信号处理系统组成。

In addition, this paper shows the design of the driving circuit of the interferential source and the design of the circuits monitor based on LabVIEW.

另外，本文还进行了光源的驱动电路系统设计和基于虚拟仪器的电路监控系统设计。

The crux is that these colors are mostly equally dominant (and therefore leave us with great artistic and interpretational freedom) as opposed to any other lighting condition, where there is usually one light source which is predominant.

最关键的问题在于这些颜色常常具有同等的强度优势。（因此留给我们用伟大的艺术眼光和自由的解释权来说明这些问题）---这与其他任何一种灯光系统条件不同的是，正常情况下，都会有一个主导光源，而这却没有。

E. , considering solar radiation, scattering, absorption, reflection and diffusion of light wave in the atmosphere, reflection and interreflection of the object surface, image rendering, and photorealistic image synthesis in the raster screen. The research has the merits of validity of theory and practicability of the model.

本文综合了太阳能、辐射传输、光照模拟、图形着色和图象合成等方面的研究成果，建立光照变化与景物成像之间的定量关系，完成从光源分析到图像合成整个流程的工作，即太阳辐射、光波在大气层中的散射、吸收、反射和漫射、对物体表面的反射和互反射进行分析和着色、最后在屏幕上合成人眼应该看到的真实图像。

The system had advantages of the invariableness of light source and long stable working time, which improved the image collecting precision greatly.

该系统光源恒定、处理速度快、图像精度高，能长时间稳定工作，显著提高了图像采集质量。

Using ultraviolet lamp as light source, the photocatalytic activity of photo-assisted mesoporous TiO_2 katalyst was studied by photodegradation of Rhodamine B.

以紫外灯为光源，通过对水溶性染料罗丹明B的光降解反应，考察了光助中孔TiO催化剂的光催化活性。

Each encoder contains a lensed LED source, an integrated circuit with detectors and output circuitry, and a codewheel which rotates between the emitter and detector integrated circuit.

每个编码器包含一个透镜LED光源，一个探测器和集成电路输出电路和一个编码轮的发射器和检测器之间的旋转集成电路。

Using the developed LECS system, four settings of light quality (pure red light, pure blue light, R/B ratio = 1:2 and R/B ratio = 2:1) were applied to tissue culture experiments of Limonium. The results show that: leaves developed under pure blue light become thiner, whiter and lower in chlorophyll content.

利用上述之光环境控制系统制造出纯红光、纯蓝光、红蓝比1：2与2：1等四种光质特性之光环境，控制总光度各约为 100μmol m-2 s-1 (离样本之高度为 5 cm )，於星辰花组培苗栽培试验及出瓶后驯化，并以传统日光灯管光源栽培作为差异比较。

The bird to die in abundance, only remains, lonelily is standing and waiting for a long time, that is a messenger bird!

大家跑来，每人手里拿着光源）鸟纷纷死去，只剩一只，孤单地伫立着，那是青鸟！

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。
