| 摘 要： | 对比研究了入射激波诱导下纳米铝粉和微米铝粉与环氧丙烷混合物快速反应系统中的爆炸特征.利用多台单色谱仪同步采集技术实验测定了二种反应混合物在不同诱导激波中强度作用下的点火延迟时间.为获得爆炸系统内部信息利用扫描电子显微镜(SEM),X射线衍射分析仪(XRD),X射线能谱(XPS)对相应铝粉反应生成物的结构、态貌、表面氧化层厚度进行了表征和分析.结果表明:TEM结果表明纳米铝粉生成物为絮状、针状和纤维状,而微米铝粉生成物为球状且体积增大;XRD结果显示在压缩区、点火区、燃烧区、爆炸区、传播区、碎片压缩致冷区生

| Abstract: | The explosion characteristic of propylene oxide/nano-,micro-alumium component were comparably investigated under the changed induced incident shock waves.The ignition delay times of two explosion systems were determined by the monochromater synchronous test technology.The structure,morphology,surface oxide layer of the products were analyized by scanning electron microscopy(SEM),X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS).The results indicated that the products of nano-Al are the spongy... |
