| 中文摘要: |
| 爆炸驱动的干粉灭火剂或水灭火相对于传统灭火方式具有高效、便捷等优势，可应用于森林、草原和高层建筑物等火灾扑救。为了研究干粉和水介质爆炸运动特性及其灭火效果，采用HX-3型彩色高速摄像机记录爆炸水雾、爆炸抛撒干粉灭火剂灭火的全过程，发现爆炸装置直径、介质质量对两类介质爆炸抛撒过程、抛撒半径、抛撒作用时间有着显著影响；等体积的干粉和水进行爆炸灭火，水介质到达着火区域较快，而干粉驻留时间较长。文中的实验结果与分析，对提高爆炸灭火效率、优化水基或干粉基爆炸灭火弹结构，具有一定的理论参考价值。 |

| Compared with traditional fire extinguishing methods, explosion driven dry powder fire extinguishing agent or water mist has the advantages of high efficiency and convenience, etc. It can be applied in forest, grasslands and high-rise building fire put out. In order to study the kinematic characteristics and fire extinguishing effect of two typical extinguishing agents, the whole process of water mist and powder disperse in extinguishing was recorded by HX-3 type high speed colour video camera. It is found that the diameter of explosion device and agent mass have significant influence on the explosive dispersal process, the dispersion radius and spreading time of two kinds of media. When the same volume of dry powder and water were used to extinguish fire, the water medium reached the fire ignition area faster, and the dry powder remained for a longer time. Experimental results and analysis in this paper have certain theoretical reference value for improving fire-extinguishing efficiency and optimizing the structure of water-based or powder-based explosion extinguishing projectiles. |
