针对BKW(Becker—Kistiakowsky—Wilson)状态方程,编写了爆炸参数计算程序。该程序除了可以计算常规含C、H、O、N元素炸药的爆轰参数,还能计算含有其它金属元素炸药的爆轰参数。通过对含Fe、Mn元素的乳化炸药以及含A1元素的水胶炸药的爆轰参数计算表明,该计算程序得到的计算结果与实验结果基本一致,相对误差不超过1%。采用该程序计算爆轰参数时,只需输入炸药的化学式、常温常压密度和生成焓即可。
The calculation code based on BKW(Becker-Kistiakowsky-Wilson) equation of state was programmed, which was not only able to calculate the detonation parameters of traditional explosives con- taining C, H, O and N elements but also calculate those of some special explosives containing plenty of other metal elements. The detonation parameters of the emulsion explosives containing Fe and Mn ele- ments and the water-gel explosives containing A1 element were calculated using this new code and were compared with the experimental values and the data from published papers and original BKW program. The results indicated that the calculated parameters are well satisfied with those obtained from experimental data with the relative error less than 1%. In the calculation process, only the chemi- cal formula,density and formation heat of explosives at normal temperature and pressure are needed.
