摘要
基于我们的工作，本文分析了无衍射光束的物理意义，贝塞耳光束的传输变换和聚焦特性。然后，对与无衍射光束有关的一些易于混淆的概念提出了我们的看法。最后，对主要结果加以总结。
Based on our work, the physical meaning of diffraction-free beams, the propagation and transformation as well as focusing properties of Bessel beams are analyzed.Then, our commests on some confisable concepts relating to diffraction-free beams are given. Finally, the main results are summarized.
