光斑直径 meaning in Chinese
spot diameter
Examples
- Mel 80 has a very small spot of only 0 . 7mm with gaussian beam profile
Mel 80使用高斯激光束的光斑直径只有0 . 7毫米。 - The results indicate that it can obtain the laser beam with less spot and more power density , which could use in lm
结果表明，经过这种传输变换后可获得光斑直径较小的、功率密度较高的、可用于激光加工的激光束。 - It is suitable for the persons who feel dizzy when they take acupuncture and are afraid of pain , and more suitable for the old men and the children
