摘　　要：本文应用GRAY三相物态方程及Lagrange数值模拟方法，计算并讨论了康普顿散射对X射线热激波及其破坏效应的影响。计算结果表明，对较硬的X射线谱（15heVPlanck谱），康普顿散射造成能量沉积与热击波峰压明显下降，在LY－12铝中，能量沉积的相对差△E（X）／E（X）可达9％～22％，热击波峰压的相对差△Pm（X）／Pm（X）约为12％。The effects of Compton scatter on X-ray shock wave and its damage effects have been calculated and discussed by using GRAY three-phase equation of state and Lagrange numerical simulationmethod. The resulti show that, for stronger X-ray spectrum (15 keV Planck spectrum), Compton scattercan cause the depositional energy and the peak pressur of X-ray shock wave to decrease, in LY-12 aluminium, the disagreement aE(x) /E(x) range from 9 % to 22 %, △Pm(x) /Pm(x) is about 12 %.
