1. Using axicon-based optical devices can realize such transformations as Gauss' beam into a diffraction-free Bessel beam, solid beam and annular beam converting each other. 应用旋转棱镜和组合光学系统能够将高斯光束变换成“无衍射”贝塞尔光束，并能实现实心和环状光束的相互变换。
2. A high-power laser beam colliding with a high-energy electron beam produces a narrow beam of gamma rays. 高功率雷射束与高能电子束相碰时，会产生一束极窄的伽玛射线。

4. When high beam headlights are in use sensors in the Automatic High Beam system detects oncoming traffic and automatically switch the headlights to low-beam. 当远光灯大灯都在使用中的传感器自动检测系统的高光束迎面而来的流量和自动切换到低大灯光束。
5. The unit horse head polished rod close to beam suspension gravity working point . Therefore, while pump holddown beam bending moment so small that will not cause beam broken. 本机驴头悬点距游梁吊重力作用点距离很短，所以，卡泵时游梁弯矩小，不足以造成折梁。
