| 摘 要： | 报道了能量比为１：１０、间隔为２００ｐｓ、脉冲宽度为１２０ｐｓ的双脉冲激光驱动线状等离子体的Ｘ射线发射特性。通过与单脉冲驱动情况比较，获得了预脉冲作用下，等离子体轴向辐射增强的空间分布特性。并针对若干重要的辐射跃迁的增强情况，讨论了它们各自的物理原因。

| Abstract: | The effect of pre pulse on line shaped laser produced plasma X ray radiation was studied. The intensity of pre pulse is 10% of that of mainpulse, the duration of each pulse is 120 ps, and the delay of main pulse to pre pulse is 200 ps. The spatial characteristics of the pre pulse effect were obtained, and some important transitions and their physical origin were discussed. |

| Keywords: | pre pulse laser produced plasma enhancement of X ray emission |
