surface-emitting LED

This series LED is used for indoor and outdoor lighting, the light body using high quality aluminum, surface anodic oxidation process.

此系列LED用于室内室外照明，灯体采用高质量铝材，表面阳极氧化处理。

Surface Properties of GaAs IR LED Chips

GaAs红外发光管芯片的表面性质

The Au could activate surface oxygen of CeO2, which led to greatly improvement catalytic activity.

Au的加入可以活化CeO2的表面氧，从而大大提高催化剂的催化氧化能力。

The results showed that the accumulation of the organic suspended matter in the surface layer of the percolation medium because of withholding and adsorbing was the main reason that led to the clogging of the CRI system.

结果表明：污水中有机悬浮物由于截留和吸附作用而在浅表层渗滤介质中的积累是造成CRI系统堵塞的最主要成因。

Blow-by of hearth sidewall led to abnormal temperature rising near cold surface.
