摘　　要：探讨现有文献中纺纱平均特数的两种计算方法。对产量加权算术平均特数计算公式与产量加权调和平均特数计算公式这两种公式分别进行推导与分析,并举例说明了这两种公式计算所得的纺纱平均特数之间存在的差异,指出产量加权调和平均特数计算公式更具推广意义。Two kinds of calculation methods for average count in current literature were discussed. Two methods i. e. weighted arithmetic average and weighted harmonic average was derivated and analysed. The differences of average counts in two formulas were explained by examples. It is pointed out that output weighted harmonic average is much more extensive and general.
