However, these LEDs tend to produce white light with a cool, bluish tinge.

然而，这些发光二极管只产生冷的带有蓝色光晕的白光。

Shortly after replacing the battery if there is the same phenomenon, then the most likely leakage is the main board, to check whether there is any damage to the motherboard of the diode or capacitor, or use an external battery to resolve this issue.

如果更换电池后不久又出现同样现象的话，则极有可能是主板漏电，可检查主板上是否有损坏的二极管或电容，或是使用外接电池的方法来解决。

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°.

The study results shows that the breakover phenomenon in the Ⅰ-Ⅴ characteristics of SITH is due to the continual decreasing of potential and the continual increasing of anode P-N junction bias, accordingly the high injection formed in the drifting region, which leads to the hole concentration of space charge region near the gate much higher than the ionized acceptor concentration, and the space charge region reduced and can not stand higher voltage.

论文总结得到的SITH模型一即"SIT控制的二极管"模型—对分析该器件的工作机制显示了良好的作用。

Overvoltages are initially clipped by breakdown clamping until the voltage rises to the breakover level, which causes the devices to crowbar into a low-voltage on state.

保护器由一个匀称电压触发型双向交流二极管组成，过电压最初被弱钳位剪除址到电压上升至超过的级别，该级别会造成装置进入一个低电压开启状态。

This topic uses the switching mode is the entire bridge all controls the rectification filter, moreover the power source has also utilized the soft switch technology, causes its loss to reduce obviously, the DC-DC transformation use cuts the wave boosted circuit to realize, the structure is simple, the transfer efficiency is high; Selects the small breakover resistance, the high shutter speed P60N06 tube for the switching valve, to select the quick recovery diode rectification, reduces the reverse breakover time, reduces the loss.

本课题采用的开关方式是全桥全控整流滤波，而且电源还运用了软开关技术，使它的损耗明显降低，DC-DC变换使用斩波升压电路来实现，结构简单，转换效率高；选用小导通电阻、高开关速度的P60N06管为开关管、选用快速恢复二极管整流，减少反向导通时间，降低损耗。

To do this a "bridge rectifier"(a simple arrangment of 6 diodes) must be used.

这样做的"整流桥"（一个简单的安排， 6二极管）必须使用。

A conventional PFC circuit is composed of diode bridge rectifier and boost converter circuits.
