摘　　要：本文研究了在电容式条干均匀度仪上把现在的反映内不匀的变异系数,改用反映内外不匀的总变异系数来表征纱条均匀度。用上述方式计算总变异,大大提高了测量精度。The work of the paper studied to replace the current practice of characterizing strand evenness by an internal uneven variance coefficient with a total internal and external one. In this way. the testing precision is greatly improved.
