beam escape

基本解释

Limitations: Serious injury is possible if people cannot escape from the beam; skin burns within minutes.
限制：如果人们不躲避光束严重的受伤是可能的，数分钟内皮肤会烧伤。
Based on the photoelectric effect, when a beam of monochromatized radiation is shined on a sample, electrons are emitted and escape to the vacuum (Fig. 1).
利用光电效应的原理，我们用深紫外光照射样品，并探测出射的光电子（图一）。

The trapped bead will be rotated following the beam's motion before it reaches the critical escape velocity when the drag force is equal to the optical trapping force.
在该系统中，达到临界逃逸速度之前被捕获粒子会随着光束做圆周运动，在临界逃逸速度时阻力跟光镊的捕获力相等。
