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. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

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1W的光功率所需的电功率为1.51W，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197.8lm/W。

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。

In the original version of the photoelectric effect, one photon kicks out one electron, like one pool ball smacking into another.

在最初的光电效应试验中，一个光子被用来击出一个电子，就像一颗台球击中另一颗台球一样。

And I should also add that I'm quite impressed that I can save "over $60 dollars" when I plunk down one thousand on one of your crappy bundles. I mean, that's a savings of six tenths of one percent!

而且我附加一条，就是我没有把1000美刀砸在那些垃圾捆绑套装中，并且节省了"60美刀"，我的意思是，那是节省了几乎60％的开销！

Those Fourth of July celebrants taking this week off can spend some of their leisure hours reading one of the many new books on the subject, including Richistan, a rollicking guide to the America inhabited by the super-rich written by a Wall Street Journal reporter, or The Manny, a novel about the family life of the Park Avenue plutocracy, as witnessed by one of its daughters, Holly Peterson – as in Pete, one of Blackstone's co-founders.

现在有很多关于这个主题的新书，包括《富人国》，一本关于美国超级富豪的戏谑指南，由《华尔街日报》记者撰写；或者是《男保姆》，一本描述公园大道富豪阶层家庭生活的小说，全书以家族的一个女儿霍莉·彼得森为视点，就像彼得家一样。彼得是黑石的联合创始人之一。

Because drank wine, he already forgot from the back still pulled a tractor the boss is very fast overtook BMW, proper they with 280 stridden speed whirlwind cars when, was discovered by a pointsman of roadside, want to bar had had not enough time, take out interphone at once, follow police of below one a section of a highway to contact: Hello, hello, hello, discover two Che Zaibiao cars, rate is very rapid, one is BMW, one is to run quickly 600, ask your block them, incorrect, it is 3 Che Zaibiao cars, return from the back closely follow a tractor, and the tractor still is hitting left-hand rotation Xiang Deng, miss overtake other cars on the road...

因为喝了酒，他已忘了后面还拖了一辆拖拉机老板很快的追上了宝马，正当他们以280迈的速度飚车的时候，被路边的一个交通警察发现了，想拦已经来不及了，连忙拿出对讲机，跟下一路段警察联系：喂，喂，喂，发现两辆车在飚车，速度非常快，一个是宝马，一个是奔驰600，请你拦阻他们，不对，是三辆车在飚车，后面还紧紧的跟着一辆拖拉机，并且拖拉机还打着左转向灯，想超车
