摘　　要：研究了X射线在金属腔体内激发的系统电磁脉冲响应,给出了其中的电磁场幅度、波形和分布曲线。计算结果表明:X射线透射入系统后,8 4J/cm2的注量在靠近试体表面和金属壳体表面附近被激励的电场高达106V/m量级,对部件形成相当的威胁,有必要对部件采取加固措施。The system-generated electromagnetism pulse (SGEMP) response is researched for column model in metal cavity by X-ray, and the amplitude, waveform and distribution of electromagnetic pulse are given. The result shows that electric field nearby the surface of metal shell and column model with X-ray in system at the fluence of 8.4 J/cm2 is as high as 106 V/m, and it is quite harmful to system parts. It is necessary to take reinforce step.
