粒子

By the historical and methodological pondering over the development process of modern physics,based on the research work done by Arndt,Zurek,Brune,Myatt and so on,the problem of the wave-particle duality,the boundary between classic physicsand quantum physicsand the quantum decoherence of object particles is extended to the boundary of electromagnetic fields between classic and quantum in this paper.

本文通过对现代物理学发展过程的历史学与方法论反思，在阿恩特、哲瑞克、布鲁尼、莫雅特等人工作的基础上把实物粒子的波粒二象性、经典物理与量子物理的界限以及量子退相干问题推进到了电磁场的经典与量子界面上，并就反康普顿散射的经典理论与量子理论进行了比较研究，发现了洛仑兹-康普顿佯谬并设计了一个敏感而可行的双胜判决性实验。
