摘　　要：通过三刺激值测量及数学校正方法,对低亮度条件下 CRT 的色度特性作了分析,发现该条件下 CRT 仍然具有通道独立性和色坐标的一致性。因此,采用了适用中高亮度条件的数学模型,对低亮度条件下 CRT 的颜色复制进行预测并得到了与中高亮度条件下相当的预测精度。The CRT's colorimetric characterization under low luminance condition was studied with tristimulus measuring and data correcting method and it was found that the CRT still has channel inde- pendence and nearly exhibits channel chromaticity constancy.A mathematical model that has been veri- fled to be applicable under middle luminance condition was used for colour reproduction predicting on the CRT and the predicting precision was reasonable high compared with middle luminance condition.
