摘　　要：稳定性是光电式测色仪的一项重要技术指标,光电式测色仪在长时间重复使用时,受环境温度变化以及光源色温变化的影响,色差测量的结果会产生较大漂移,严重影响测量精度,经常需要对仪器重新进行标定,通过改进积分球的结构,改进电源方案及增加辅助测量环节,避免重复标定,有效提高测量稳定性。Stability is an important technical index parameters to for evaluating photoelectric colorimeter. When it was reused for a long time, the result of measurement will be drifted largely, which can influence the precision of measurement seriously. So the instrument has to be anew calibrated frequently, which is due to the effect of ambient temperature and source color temperature change. However,by improving the structure of integrating sphere and the power supply scheme and adding measurement-aided link,repeated calibrating is avoided and the measuring stability is imoroved effectively.
