By analyzing and calculating work on the spectroscopic diagnostic results, the quantitative relationship between the electron density of laser induced plasma and linear heat input as well as the relationship between electron density and factor of absorption are deduced.

通过对激光等离子体光谱诊断结果的分析、计算，定量地得到了等离子体粒子密度与焊接线能量之间的函数关系以及粒子密度与吸收系数的函数关系。

The parameter of laser energy transfer efficiency is used in the new model with a clear physical meaning for the first time. The mean absorption factor of laser induced plasma to the laser within the keyhole is calculated according to different welding parameters using the relative intensity method of spectral lines.

首次有机地将激光焊接能量传输效率这一重要的焊接参数以明确的物理意义引入数学模型中；通过谱线相对强度法计算推导出每一个焊接规范下小孔内等离子体对激光的平均吸收系数。

The plasma density scale length decided by main laser pulse in the experiment is suitable for Vacuum Heating, and it is the domiant process for hot electron generation. From the scaling law about hot electron temperature given by VH model, the hot electron measured by experiment was reasonable, the temperature was higher than the temperature given by Rcsonant Absorption scaling law.

从真空吸收给出的超热电子温度的定标率来看，实验中测量得到的超热电子温度是合理的。X射线是各向同性的，X射线产额随入射激光强度的降低而减小，当强度小于10〓W/cm〓时，不再有硬X射线产生。
