摘　　要：目的　了解炸药在二维接触爆炸情况下输出的压力 -时间关系 .方法　推导了炸药二维接触爆炸情况下输出压力 -时间的 p-t关系式 ,并且以传爆药柱 -惰性介质二维接触爆炸为例进行了数值计算 ,对理论结果进行了实验验证 .结果　实验结果与理论预测相吻合 ,相对误差不超过 7% .结论　理论结果可用于Aim\ To obtain the relation between output pressure of explosive and time under the condition of two dimensional explosion. Methods\ A \%p-t\% relationship between output pressure of explosive and time under the condition of two dimensional explosion is derived. The numerical calculation of \%p(t)\% relation between the booster pellet and the medium was made as an example. The theoretical results are compared with the experimental results.Results\ Experimental data well conform with the theoretical prediction, within 7%. Conclusion\ The theoretical results can be used for numerical calculation of \%p t\% relation for engineering use.
