The result showed that the luminous flux for LW white LED radiation power output is 298.7 lm and the total photons are 2.7×1018. If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons.

在理想情况下，注入一个电子-孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子-孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1 W的光功率所需的电功率为1.51 W，上述白光LED发光光谱对应的白光LED的电-光转换的理论极限流明效率为197.8 lm/W。

The asphalt is hard and is dug out with a big scoop shovel or a pick,leaving a hole in the surface of the lake.within a week or two the hole is filled with new asphalt that pushes up from below.the supply of asphalt seems to be endless.

The asphalt is hard and is dug out with a big scoop shovel or a pick,leaving a hole in the surface of the lake.Within a week or two the hole is filled with new asphalt that pushes up from below.

一则古老的传说解释了沥青湖的来历：许多世纪以前，两个印地安人部落打了一次大仗，获胜的部落建立了一个村庄，并举行胜利庆典，他们杀死了数以百计的美丽的蜂鸟，吃了鸟肉，并且用鸟的羽毛装饰他们的衣裳；伟大的圣灵被这些蜂鸟惨遭杀害所震怒，便让全村沉入地下。

Such a tie was to be decided by a hole-by-hole play-off, which was scheduled to be played immediately.

最后的一个名额要通过一洞接一洞的延长赛来决定，而且安排立即进行。
