摘要
本文利用微焦点体积CT(μVCT)技术和同步测试方法,研究含能材料体密度与体积CT灰度值的相互关系,探讨相近密度范围内含能材料试件的密度测试方法。采用该方法可以分辨出样件间0.1%的密度差;在样件密度变化范围为2.5%时,试件体密度-体积CT灰度值的线性相关系数达到0.999。
Relationship between energy material volume density and volume CT gray value was studied by micron focus volume computed tomography and synchronized detection. The measuring method for energy material density in narrow range was explored. The result showed that the 0.1% diversity of specimen volume density could be distinguished. The Linearly dependent coefficient of specimen volume dengsity and volume CT gray value approached 0.999, while the diversification range of PBX specimens dengsity within 2.5 %.
