查询词典 a pair

The new algorithm called PCTwig was proposed for this problem, which was based on the ordered pair. The twigs were queried through setting the ordered pair of parent-child relationship on query tree and document tree.

针对该问题，提出了一种基于有序对的新算法PCTwig，通过在查询树和文档树上分别建立父子关系的有序对来进行查询。

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.
