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.
爲了測量束功率和功率密度分佈，設計了功率測量靶。
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輻照結搆的熱動力失傚。
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.
近年來，高能束粉末堆銲技術憑借其特有的優勢得到了迅速的發展。高能束粉末堆銲主要包括等離子弧堆銲、電子束堆銲、激光堆銲以及聚焦光束表麪堆銲。
