摘要：
The numerical simulation of the accelerating process of laser-driven flyer plate was described using one-dimensional (1D) bulk absorption model. A modified 1D Lagrangian hydrodynamic code was used to describe the gasdynamical behavior of the ablated foil plasma in the laser intensity range of 10 8-1010 W/cm2. The model provided spatial and temporal distribution of field parameters including velocity, temperature, opacity and average ionized charge number. The calculated particle velocity distribution in plasma is linear, which confirms the assumption employed in the Gurney model.
