Explosives containing metals and the other solid particulates have wide applications in air‐blast and underwater explosives. Due to the non‐ideal behavior of these explosives, available complex computer codes and empirical methods cannot usually provide a reliable estimation of their detonation velocity. Large experimental data of detonation velocity (392 experimental data) corresponding various types of ideal and non‐ideal explosives were collected from different sources to derive a general correlation. The new model assumes partial secondary reactions of metal and active particulates with gaseous products. Optimum values of different products are obtained by maximizing the coefficient of determination (R²) of the correlation and minimizing the mean absolute percentage error (MAPE) of the calculated results from experimental values of detonation velocities. The MAPE values of the new model and one of the best available methods are 3.55 and 11.16 respectively, for 90 non‐ideal explosives, which confirm much high reliability of the new method.

改进的相关性，可可靠地评估包含金属和其他固体微粒的非理想炸药的爆炸性能

含有金属和其他固体颗粒的炸药在气炸药和水下炸药中具有广泛的应用。由于这些炸药的不理想行为，可用的复杂计算机代码和经验方法通常无法可靠地估算其爆炸速度。从不同来源收集了对应于各种类型的理想和非理想炸药的大爆炸速度实验数据（392个实验数据），得出了一般的相关性。新模型假定金属和活性颗粒与气态产物发生部分二级反应。通过最大化确定系数来获得不同产品的最佳值（R ²）的相关性，并根据爆炸速度的实验值将计算结果的平均绝对百分比误差（MAPE）最小化。对于90种非理想炸药，新模型的MAPE值和可用的最佳方法之一分别为3.55和11.16，这证实了该新方法的高度可靠性。
