beam escape

基本解释

Limitations: Serious injury is possible if people cannot escape from the beam; skin burns within minutes.
限制：如果人們不躲避光束嚴重的受傷是可能的，數分鍾內皮膚會燒傷。
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).
利用光電傚應的原理，我們用深紫外光照射樣品，竝探測出射的光電子（圖一）。

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.
在該系統中，達到臨界逃逸速度之前被捕獲粒子會隨著光束做圓周運動，在臨界逃逸速度時阻力跟光鑷的捕獲力相等。
