摘　　要：He-Ne激光能促进孔雀绿的阳极氧化速度,增加峰电流的增长速度,但对孔雀绿母体峰电流的增长速度反而减小。溶剂参数π^*与孔雀绿的氧化电位Eox₂及吸收光谱的λ_max间有线性关系。在DMSO溶剂中,发现氧化后的孔雀绿,在可见光谱有“烧洞”现象。并观测了“激光诱导后期效应”。In this paper, it was found that the He-Ne laser can promote the anode oxidation and increase the rising rate of peak current of malachite green but decrease the rising rate of leuco-malachite green. There is a linear relationship between the solvent polarity parameter π* and oxidation potential Eox2 or the λmax of the UV/VIS spectra of malachite green. In DMSO, a 'hole-burning' phenomenon was observed in the spectrum of malachite green when it was-oxidized. Some 'laser induced after effect' was observed.
