摘要
反应性光声谱技术（ＲＰＡＳ）是近年来发展起来的一门新技术，它用于研究激光与物质互作用和快速的凝聚相化学反应。利用这一技术研究了激光与含能材料互作用的过程。研究发现并证实了脉冲激光激发下凝聚相的化学反应由光激发化学反应、慢速化学反应和快速加速的化学反应等三个阶段构成，反应性光声谱呈现出明显的双峰。
Reactivity photoacoustic spectrum technology(RPAST)is a new technology developing recently.It is applied to research interaction of laser and materials as well as fast chemical reaction of condensed phase.In this paper the technique was applied to study the interaction process of laser and energetic materials.It was found and verified that the chemical reaction of condensed phase excited by pulsed laser consists of three stages,photochemical reaction,slow chemical reaction and fast accelerating chemical reaction,and the reactivity photoacoustic spectrum has a typical double peak.
