混合炸药爆速预报的新方法

为了提高混合炸药爆速尤其是含铝混合炸药爆速的计算精度，基于体积加权法思路构造一种新的混合炸药爆速计算公式，对近50种常见的混合炸药配方进行了计算，并与实验值进行对比，结果很好吻合，最大误差低于3%，平均误差低于1%，与BKW和Urizar常用方法相比，计算精度有显著提高。

A new method for predicting detonation velocity of composite explosive

In order to predict detonation velocity of composite explosive accurately (esp. aluminium-containing explosive), a new equation of predicting detonation velocity of composite explosive was derived in the weighted-volume method. With the new equation, prediction of detonation velocity was carried out for more than 50 kinds of composite explosive. The predictions show a good agreement with the experiment data. The maximum error of prediction was less than 3%. The average error of prediction was less than 1%. Compared with that of commonly used methods such as BKW and Urizar, the prediction accuracy of the new equation was significantly improved.
