Abstract:
A two-phase repellent-translation equation of state of explosive detonation product (two-phase R-TEOS) was obtained. Using the two-phase R-TEOS and a known isentropic through the CJ point of an explosive as reference curve, the detonation parameters for various densities of the explosive can be estimated. The comparing the experiment data of detonation velocity for various initial density values of TNT which detonation product contains more solid carbon with the theory values estimated with above mentioned method, a new test of the hypotheses of the ZND theory was performed. The experiment and theory values of detonation velocity for various density values (from1.632 g/cm3to 0.901 g/cm3) are in good agreement, and their average relative difference is only 0.60%. The conclusion was drawn again that the hypotheses of the the ZND theory of detonation are true, and the two-phase R-TEOS is a proper equation of state of detonation product.

用TNT的{D,ρ0}实验数据对爆轰的ZND理论的检验
李银成*
摘要:
爆轰产物中或多或少含有固态碳,一相的排平物态方程被推广为两相的之后,以某种炸药的一条已知等熵线为参考曲线,就可以用来估算其各种初始装药密度下的爆轰参数.用产物中含碳量较多的TNT的{D,ρ0}实验数据与理论估算值相比较,可以对爆轰的ZND理论的假设进行检验.检验的结果再一次表明,爆轰的ZND理论的假设是成立的,并且排平物态方程是恰当的爆轰产物的物态方程.
