一个描述强激光驱动飞片高速运动的Gurney模型

在Gurney模型的基础上，结合变质量体系的动力学方程，提出了一种简单地描述在真空环境中强激光驱动飞片高速运动的计算模型．以强激光驱动铝飞片为例，根据一组飞片厚度（10μm）的速度实验结果，确定了模型中的激光／飞片能量耦合参数，并且通过与其他不同厚度飞片的实验结果比较表明，该模型在较宽的激光加栽强度范围内，对飞片运动的速度均有比较好的描述和预测能力，该模型具有一定的普适性．

A Gurney Model for the High Velocity Launch of Laser-Driven Foil Plate

In the framework of Gurney theory and the kinetics equation of changeable mass system, a simple model to calculate the final velocity of a laser-driven foil plate in vacuum condition has been proposed. To certificate this model, examples are presented by comparing the model computation with the experimental measurement for aluminium foil plates. Results indicate that the new model has a good ability to describe the velocity variations of foil plates with different thickness and in a wide laser energy range.
