This paper describes two microcomputer programs of electron diffraction spot patterns.
本文介绍了两种电子衍射花样的微型机分析程序。
Then the diffraction spot size is decreased, and the optical resolution is increased, so the accuracy of the fine tracking system is improved.
由此减小接收衍射光斑的大小，提高系统的光学分辨能力，从而提高精跟踪系统的精确性。
Highly visible stationary laser diffraction patterns from liquid surface waves at a few tens Hertz were obtained experimentally, and the disappearance of zero order diffraction spot was also observed.
对于频率为几十赫兹的液体表面波，实验上观察到稳定、清晰、反衬度非常高的衍射图样，并发现了零级缺级现象。
