beam power density

基本解释

To measure the beam power and the distribution of beam power density, as an emphasis, a calorimeter is designed.
为了测量束功率和功率密度分布，设计了功率测量靶。
The thermodynamic failure of the structures irradiated by laser beam with low power density are studied in this paper.
研究了低功率密度激光辐照结构的热动力失效。
In recent years, high power density beam powder surfacing techniques have been developing rapidly, such as plasma arc surfacing, electron beam surfacing, laser surfacing and focusing light surfacing.
近年来，高能束粉末堆焊技术凭借其特有的优势得到了迅速的发展。高能束粉末堆焊主要包括等离子弧堆焊、电子束堆焊、激光堆焊以及聚焦光束表面堆焊。
