The reflection spectra of Al0.5Ga0.5As-AlAs distributed Bragg reflector at different incident angle are calculated by transfer matrix method.

采用传输矩阵法对Al0.5Ga0.5As-AlAs材料的发光二极管分布布拉格反射器进行入射角的反射光谱研究，计算发现反射偏振光p和s随入射角的增大呈"V"形变化，在49.8 处有最小反射值。

The reflection spectra of Al0.5Ga0.5As-AlAs distributed Bragg reflector at different incident angle are calculated by transfer matrix method. The reflection spectra curve of p-polarized and s-polarized plane waves vary with a 'V' shape with the rise of the incident angle and the lowest reflectivity is at 49.8°.

Proton generated from a Cockroft-Walton accelerator in the energy range of 30-100 keV were appropriately collimated and made to pass through a 10 g/cm^2 carbon foil. After Rutherford scattering, proton uniformly irradiated TLDs which were placed at the 20° behind and 20 cm away from the carbon foil. We used a channeltron behind TLD holder as the proton detector.

由Cockroft-Walton加速器提供之质子源，能量在30~100keV间，经准直后通过一10 g/平方公分之碳膜做拉塞福散射，散射后之质子均匀打在置於其后20°的压克力置装器内的热发光剂量计，利用压克力置装器后之一电子倍增器作为量测质子工具。

X9313U-WS Pinout: The coupler consists of a AlGaAs LED that is optically cou- pled to a dielectrically isolated photodiode array which drives two series connected high voltage MOS transistors.

X9313U-WS引脚说明：该耦合器由一个砷化铝镓发光二极管是光凑发光二极体为介质隔离光电二极管阵列的驱动两个串联的高压MOS晶体管。

Since photoemissive materials are very inefficient, the time that the pinhole has to look at the point source in order to collect enough electrons tends to make image dissectors rather slow digitizers.

由于光电发射材料效率是非常低的，要收集到足够的电波，解析器背后的小孔发光就为不得不依赖于图像的点源，这使图像解析器成了非常慢的数字转换器。

After analyze existing headlamp adjuster, we can find that the main research of headlamp adjuster is almost about the efficiency of light bulb, shine angle of reflector, and how to automatic control headlamp adjuster now.

经分析现有车头灯调整机构后，可发现目前对於车头灯的研究，大多以著重於灯泡的发光效率、反射器的投射角度、以及如何自动控制整反射器为主。
