一束激光被分成几束子光束,每子光束具有不同的延时并用以不同方位放置的光栅对它编码。
A laser beam is split into several sub-beams, each of which has different delay time and is encoded by using a grating placed in different azimuth.
大型强子对撞机在位于日内瓦附近欧洲粒子物理实验室的欧洲核子中心。从周末开始,物理学家们在LHC周长为27公里的圆环内,开始质子束流的调束工作。
Over the weekend, physicists began circulating beams of protons around the 27-kilometre ring of the Large Hadron Collider (LHC) at CERN, Europe's particle-physics laboratory near Geneva, Switzerland.
根据欧洲物理研究所报道,现在,大型强子对撞机已经打破了迄今为止世界上最密集的对撞粒子束的记录,超过了台质子-反质子对撞机。
CERN reports today that the LHC has broken the record for the world's most intense beams of colliding particles, snatching the title from the Tevatron.
像陡峭山坡上的雪崩一样,一束入射光的脉冲最初仅仅释放少数的电荷载子(charge carrier),这些电荷载子再轮流释放其他的载子,直到原始信号被放大很多次。
Analogous to a snow avalanche on a steep mountain slope, an incoming light pulse initially frees just a few charge carriers which in turn free others until the original signal is amplified many times.
他指的当然是LHC(大型强子对撞机)。在阿尔卑斯山脚下,LHC成功发射粒子束,进行了第一次试验。
He was, of course, referring to the Large Hadron Collider that just conducted its first successful test, firing a stream of particles under the Alps.
灯光变暗,幻灯背景片消失,一束追光投在一男子身,他身着军装,头戴贝雷帽。
The lights go to black and SLIDES FADE OUT . A spot falls on one man who is in a legion suit and beret.
我起床刚走出房间,就看到妈妈摆满一桌子的糖果、水果……还有一束美丽的鲜花,好看极了!
As soon as I got up out of the room, we see mom with a table of candy, fruit…
子束随机像差降低了合成光束的远场光斑峰值功率,并引起光束的弥散。
The random aberration of each beam reduces peak intensity of their far-field combination spot, and makes it dispersion.
光学聚焦传感器包括分束器,该分束器配置为将辐射光束分为第一子光束和第二子光束。
The optical focus sensor includes a splitter configured to split the radiation beam into a first sub-beam and a second sub-beam.
