中文摘要：

等离子体连续辐射谱反应了轫致辐射和复合辐射总效果,通过对连续谱的拟合可以给出等离子体的电子温度信息。基于Z箍缩钠等离子体的连续辐射谱数据,提出以最优化的观点来拟合实验数据,可以充分将实验中涉及到的多种未知变量作为不定参数考虑进去,比普遍采用的直线拟合更准确,其残差平方和仅为后者的1/3.6,同时与共振线强度比得到的电子温度非常符合,说明了该方法的有效性。

英文摘要：

Plasma continuum is composed of bremsstralung and recombination radiation,and the electron temperature could be obtained by fitting the continuum.Fitting experiment data with optimization viewpoint is proposed for sodium plasma continuum in Z-pinch,which can evaluate unknown variables in experiment,and the method is more accurate than linear fit which is adopted usually.The electron temperature from the optimization method accords with resonance line intensity ratio,showing that the optimization is valid.
