摘要
本文从理论上分析了Ｘ光机输出射线的特性及影响初始谱分布的因素；提出了Ｘ光机辐射能谱调制的附加过滤法。Ｋ荧光辐射法、脉冲幅度甄别法和平衡差滤法，并对这些方法的原理及具体应用进行了较详细讨论。
This paper mainly analyses the property of output from X ray units and the factors influencing the primary photon energy spectra, and gives the methods for energy spectra modulation, including additional filtration, K fluorescent, pulse amplitude discrimination and equilibrium difference filter. Their principles and applications were also described. (
