光谱学

The spectrogram suggested that the absorption peak of the pigment was 627nm in alkalinous condition, 527nm in acidic condition.

光谱图谱表明该色素碱性条件下最大吸收峰在627nm处，酸性条件下最大吸收峰在527nm处。

On the basis of theories of plasma physics and optical spectroscopy a new method named Multilineal Spectroscopy Analytic Solution for diagnosing are plasma is proposed.

根据等离物和光谱，建立了一种电弧等离测试方法─—光谱多线解析法，可对未知配比混合电弧等离成分、温度甚至压力空间分布作同时测定。
