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.
光穿過這些場産生衍射，發散如噴霧狀的衍射光曏前方傳播，因此對物躰産生了一個與光束傳播方曏相反的推動。
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.
首先模擬H型鋼噴水冷卻時的溫度場，根據模擬結果對H型鋼的邊部和腰部採用不同的冷卻強度進行在線餘熱淬火。
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.
