摘要: 对于爆轰驱动平板问题，当由理论近似给出或实验拟合给出某些物理量后，可以借助抛射角方程导出适用的抛射角公式。利用爆轰驱动平板的抛射角方程，在小抛射角条件下，假设切向速度大小随时间的变化率为零，很容易得到周培基（P.C.Chou）公式。考虑切向速度大小随时间的变化率时，运用抛射角方程对周培基公式进行改进，得到了更为精确的抛射角公式。与实验结果相比，改进的周培基公式计算结果与实验结果更接近。Abstract: For the problem of detonation driving plate, if some quantities could be gained from theories or experiments, we can deduce the projection angle formula from the projection angle equation. Using the equation, regarding the projection angle as a small quantity, neglecting the differentiation of the absolute value of the tangential velocity with respect to the time, the P.C.Chou formula was easily obtained. When considering the differentiation of the absolute value of the tangential velocity with respect to the time, the improved P.C.Chou formula was obtained. Compared to the P.C.Chou formula and Taylor formula, the results from the improved formula are more close to the experiment.
