您要查找的是不是：
- These procedures reduce the number of electrons in the upper band, which minimizes their reabsorption of light. 这些程序会减少位于上层能带的电子数目，从而降低电子再吸收光的比率。
- The electrons in the upper band eventually release energy, thereby emitting photons. 上层能带中的电子最后会发射光子释放能量。
- On the other hand， if price tags the upper band and indicator action does not confirm (that is， it diverges). we have a sell signal. 在另一方面， 如果价格标注，那么上面的线和指数行动不证实(那是， 它分歧)。我们有一卖信号。
- In between overall reviews, directorate salaries were adjusted annually on an interim basis in line with the increase for the upper band of non-directorate staff. 在两次全面检讨之间,首长级每年按非首长级高层薪金级别的加薪幅度,暂时调整薪酬。
- In this phenomenon, rather than emitting light, an electron in the upper band loses its energy to other electrons that subsequently give up the excess energy as heat. 在这种现象中，位于上层能带的电子释放能量时不会发出光，而是将能量传给其他电子，其他电子再将这些多馀的能量化为热放出。
- Silicon undergoes more Auger recombination than does gallium arsenide because it needs more electrons to be pumped into the upper band to overcome its low light-emission efficiency. 矽的奥格重合发生率高于砷化镓，因为矽需要推送更多电子到上层能带，才能克服过低的发光效率。
- A band or badge worn around the upper arm. 臂章戴在上臂的绑带或徽章
- The upper bands (or buckets) in good lasing materials such as gallium arsenide are narrow and have steep sides, so they tend to hold relatively few electrons. 在砷化镓等发光效率较高的雷射材料中，上层能带（或桶子）相当窄，两侧曲线很陡，因此可容纳的电子数目比较少；
- He left when the band began to beat out pop music. 乐队一奏起流行音乐他就走了。
- Tears are secreted by an organ under the upper eyelid. 眼泪由上眼睑下面的器官分泌。
- The band played a military march. 乐队吹奏军队进行曲。
- A live band is always a good draw at a party. 现场演奏的乐队在聚会上总是很吸引人的。
- I'd like a room on the upper level. 我想要楼上的房间。
- He was waylaid by a band of guerrillas. 他遭到游击队的狙击。
- Radio2 can be heard on the long wave band. 第二广播电台可在长波段收听到。
- My hometown is in the upper reaches of the river. 我的家乡在这条河的上游地区。
- The brass band is banging away in the park. 铜管乐队在公园里吹吹打打。
- He locked his diary in the upper drawer. 他把日记锁在上层抽屉里。
- He has formed a new band with his brother on bass. 他组织了一个新乐队，由他弟弟弹低音吉他。
- He was attacked by a band of ruffians. 他遭到一伙暴徒袭击。
