decrease beam

基本解释

That is the system adopting slipping-foot without base beam decrease the earthquake shear effectively, and its whole behavior is even.
即无梁滑动支座结构体系有效地减少了底部总剪力，并且整体力学性能均匀。
With an identical vehicle running speed, the vibration response of the bridge increases with the decrease of track beam bending rigidity.
在相同车速下，随着轨道梁抗弯刚度的降低，桥梁振动响应增大；
The TEC single-mode fiber-coupled laser module is used to decrease the laser beam drift, and the high accurate and stable measurement reference can be obtained.
系统采用带有温控的半导体激光器单模光纤组件作为光源，有效地降低了激光器本身的光线漂移，为滚转角误差测量提供了高精度和高稳定性的基准光线。
