| 摘 要： | 激光聚变靶物理研究用激光强率I随空间的变化来反映激光能量的沉积。目前激光靶物理研究使用的激光能量沉积方程在临界面处发散，讨论了造成这一非物理结果的原因，给出了合理的激光强度方程，并讨论了新旧两种激光强度方程对激光吸收的影响。

| Abstract: | Laser energy deposition is described by the spatial derivative of laser intensity in the simulation study of the laser-target interaction. But the equation for laser energy deposition used in our presentcode is divergent on the critical surface. In the present paper, a modified equation for laser energy deposition,which does not contain singularity, is derived. Some discusses and one dimensional laser-target interactionsimulation results are presented. |
