Another electroluminescent and has the type of light source such as light source.

另有场致发光和蓄光源等光源种类。

LED light source is characterized by long service life which can be 80,000 to 100,000 hours, over five times that of traditional light source, and low energy consumption. With an over 90% electrooptic power, it can save over 80% energy when compared to traditional lighting.

LED光源使用寿命长：可达到8万~10万小时，是传统光源寿命的5倍以上；低耗能：电光功率达90%以上，比传统照明效率节能80%以上。

The Middle Proterozoic Caiziyuan peridotite was formed in the epicontinental basin at the ocean-land boundary or within-continent rift basin. Its mantle source could be metasomatized by the dehydration fluid of subducted plate, and much initial radioactive 〓Nd was added to the source.

中元古代菜子园橄榄岩形成于洋陆交界的陆缘盆地或与大洋相连的陆内裂陷盆地，其源区可能受到俯冲板块脱水流体的交代作用，有大量初始放射性〓Nd加入。

Ethical or ethicoreligious dualism asserts that there are two mutually hostile forces or beings in the world, the one being the source of all good, the other the source of all evil.

道德或ethicoreligious二元断言，有两个互相敌对势力，还是在世界上，其中之一是从源头上的一切好外，其他万恶之源。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

The results showed that the highest yield of GLP among six strains was ShuShe.The effects of carbon source, nitrogen source, salt and the optimum initial pH value of medium on GLP produced by ShuShe were studied in liquid and solid fermentation respectively. The liquid and solid fermentive medium of high yield was selected by orthogonal experiment.
