摘　　要：利用分幅相机拍摄了不同实验条件下的 XeF2 光解离波图像,反映了解离波的形成过程,获得了不同XeF2 初始浓度下光解离波半径、解离层厚度、发展速度随时间的变化曲线,分析了光解离波参数的时间、空间特性。结果表明,光解离波在目前实验条件下所达到的最大距离约 3 cm,解离波发展速度最大达 28km/s;XeF2 初始浓度越低解离波半径越大,发展速度越快,解离层厚度越厚。The framing photographs of XeF2 photodissociation wave (PDW) under different experimental conditions have been taken, showing the forming process of the PDW. The variations of the radius, thickness and developing velocity of the PDW with time were obtained under different primary XeF2 concentrations. The temporal and spatial characteristics of the PDW were analyzed. Results show the maximum travelling distance of PDW is about 3 cm, and the maximum developing velocity of the PDW is about 28 km/s. As the primary XeF2 concentration is lower, the radius will be larger, the developing velocity higher and the PDW thicker.
