spray beam

基本解释

The spray of light scattered forward by these fields could push the object backward, against the movement of the beam itself.
光穿过这些场产生衍射，发散如喷雾状的衍射光向前方传播，因此对物体产生了一个与光束传播方向相反的推动。
Firstly, the spray cooling temperature field for H-beam was simulated. Then different cooling rates were adopted for edge and waist parts of the beams according to the simulated results.
首先模拟H型钢喷水冷却时的温度场，根据模拟结果对H型钢的边部和腰部采用不同的冷却强度进行在线余热淬火。
Comparing with the plasma spray technique and the electron beam physical vapor deposition has led to the incorporation of very durable coatings into the most demanding rotating turbine components.
