针对近年来新发现的典型高能物质特点进行了分类和性能总结,通过炸药类高能物质的能量特征研究了高功率密度能量的输出特性,得到了能量密度与能流密度的输出差异;从作用时间及空间特征尺寸角度重新认识了常规高能物质的高功率密度特性,并对未来的发展提出了展望。结果表明,高能物质能量的高功率密度输出能够达到其他常规材料所无法比拟的量级差距,优化高能物质的装填结构和能量激发序列设计能够使相同质量炸药的爆炸输出功率差别达到1~4个数量级,能量密度差别达到1~2个数量级,能流密度差别达到1~6个数量级。

Aiming at the characteristics of newly discovered typical high-energy matters（HEMs）in recent years,the classification and performance summary of HEMs were carried out.The output characteristics of high power density matters were studied through energy characteristics of HEMs of explosives,and the differences of output between energy density and energy flux density were obtained.The high power density characteristics of conventional HEMs were reconsidered from the angle of action time and space characteristic dimension,and the future development was prospected.Results show that the high power density energy output of HEMs energy can reach different order of magnitude that other conventional materials can not compare.Optimizing the loading structure of HEMs and the design of energy excitation sequence can make the difference of explosion output power of the same mass explosive reaches 1-4 order of magnitude,the difference of energy density reaches 1-2 order of magnitude and the difference of energy flux density reaches 1-6 order of magnitude.
