摘　　要：利用电注入着色装置,使用点阳极和平板阴极在不同条件下对氯化钠晶体进行电注入着色。在着色晶体中产生大量V、F、胶体C和N心。对着色晶体进行系统的光谱测量,确定色心光谱吸收带的光谱参数。研究不同注入条件对色心浓度的影响。测得电流～时间关系曲线。计算出V色心的激活能小于F色心激活能,进而解释色心形成机理。Under different conditions, sodium chloride crystals were colored electrolytically using an electrolysis apparatus with a pointed anode and a fiat cathode. A lot of V, F, colloid C and N color centers were produced in colored crystals. Systematic spectral measurements were carried out to colored bands of color centers were determined. Influence of different electrolysis conditions to color center concentration was studied. Current time curves were measured. Calculated value of activation energy of V color centers less than F color centers, and formation mechanism of color center was explained.
