摘 要：
通过对终年放牧的青海藏羊毛纤维长度方向5cm区段含硫量的测定,结果表明青海藏羊毛纤维不同长度区段的含硫量不同,含硫量顶峰值前,随着长度增加含硫量逐步增加,但成年公羊顶峰值后随长度增加,含硫量逐渐减少。青海藏羊毛长5cm各区段含硫量差异不显著（P>0.05）,毛长与含硫量除成年公羊为强的负相关（r=-0.56964）,其余各性别年龄组内均为弱的正相关关系,相关系数r=-0.116 182～0.354 898。

摘 要：
The content of sulphur in 5cm fiber on the direction of wool fiber length was measured in Qinghai tibetan-sheep grazing all the year. The results showed that there was different sulphur content in different section of fiber length, and the sulphur content increased gradually with the wool length increased before the peak of sulphur content. But the wool sulphur content in adult ram decreased gradually with the wool length increased after the peak of sulphur content. There was no significant difference in the sulphur content between different sections of 5cm wool fibers in Qinghai tibetan-sheep. Except there was high negative correlation between wool length and sulphur content in adult ram(r= -0.569 64), and low positive correlation in the rest treated groups,and the correlation coefficient was r= -0.116182-0.354898.
