In an optics lab, a graduate student can spend a whole afternoon getting two mirrors to line up, and never once test the material she came to study.
optics:光学,这里指用光做测量的实验领域laser:激光lens:镜片、透镜mirror:镜子、反光镜component:组件、零件alignment:对准;corrected the alignment 是把光路重新调准knob:旋钮,调角度时转的就是它cavity:腔;laser cavity 是两镜夹一块晶体的激光腔wireless:无线的by itself:自动地、靠自己,不是"单独一个人"The system noticed the laser getting weaker and corrected the alignment by itself.
The system noticed ... and corrected ...,意思是"系统发现激光正在变弱,自己把光路调了回来"。中间的 the laser getting weaker 是 notice 后面的结构,表示察觉到一个正在发生的变化;句末的 by itself 修饰 corrected,强调没有人动手。This story was produced automatically by a channel. One sentence is all it takes for Neodrop to keep producing for you.
