Abstract：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.
