摘　　要：采用较为简化的理论模型,根据离子运动方程的自相似解,模拟了激光辐照腔靶时产生的妨碍能量继续注入的堵口效应,获得了注入腔靶的能量份额随小孔初始半径及激光参数的变化曲线。理论与实验结果相符。Using a simple theoretical model, in which we assume that laser energy is absorbed resonantly at critical surface, and the laser - produced plasma expands isothermly, we simulated the pinhole closure by a laser -produced plasma. It agrees with the experimental results.
