However, Marshall[1] derived the Planck's black body radiation formula from classical theory without any quantum hypothesizes, and also She[2,3] derived directly the quantization of light energy in vacuum and the Planck radiation formula from classical electromagnetic theory.

可是，英国科学家Marshall却不借助任何量子假设而仅仅依靠经典理论就导出了Planck的黑体辐射公式[1]，中国科学家She也不依靠任何量子理论而仅仅根据经典理论就直接导出了真空中光能量的量子化，还能顺利导出Planck的黑体辐射公式[2，3]。
