| 摘 要： | 分析比较了计算Ｘ射线辐照固体材料引起汽化反冲冲量的几种计算公式。通过对Ｘ射线辐照后材料运动过程的数值模拟和分析，提出了一种计算汽化反冲冲量的数值计算公式。计算结果表明:数值计算得到的汽化反冲冲量与ＢＢＡＹ公式的结果比较接近；脉冲Ｘ射线引起的汽化反冲冲量与Ｘ射线的能谱及辐照量有明显的依赖关系，且汽化反冲冲量随辐照量的变化是非线性的。

| Abstract: | A number of models that predict the blowoff impulse generated in solid target by pulsed X ray radiation are analysed and compared.By calculating and analysing the process of material radiated by pulsed X ray a numerical model that calculates the blowoff impulse generated in solid material by pulsed X ray radiation is given.The results indicate that blowoff impulse obtained by using numerical model is close to the result of BBAY model,the blowoff impulse is dependent on the spectra and the flunce of the X ray source,and the variance of blowoff impulse versus the flunce of X rays is nonlinear. |
