原子蒸气束二维空间纵向速度分布的激光法测量

Measurement of 2-D Velocity Distribution of Atomic Vapor by Laser Induced Fluorescence

用激光诱导荧光法测量了真空室内原子蒸气束的二维速度分布，给出了原子蒸气束的平均速度与空间方位角的关系。

D velocity distribution of metal atomic vacua was measured by laser inducedfluorescence(LIF),and an average velocity distribution vs azimuth was also given.
