您要查找的是不是:
- radar upper band 雷达高空亮带
- 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
- They picked up the yacht on their radar screen. 他们在雷达屏上看到了那艘游艇。
- 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;
- The radar scanned the sky for enemy planes. 雷达密切监视天空,搜索敌机。
- Tears are secreted by an organ under the upper eyelid. 眼泪由上眼睑下面的器官分泌。
- The watchtower followed the aircraft by radar. 瞭望塔通过雷达追踪这架飞机的行踪。
- Enemy ships were detected on the radar screen. 敌舰的影像已显现在雷达(屏幕)上。
- I'd like a room on the upper level. 我想要楼上的房间。
- The signal was picked up by a downrange radar station. 该信号被试验飞行方向之内的雷达站收到了。
- A gunboat was detected by the radar. 雷达探测出一炮艇。
- Enemy aircraft were detected by our radar. 敌机被我方雷达发现。
- The ship was provided with radar equipment. 那船装有雷达设备。
- My hometown is in the upper reaches of the river. 我的家乡在这条河的上游地区。
