摘　　要：提出了相对分离指数H(L)=exp(Lk1)-k2Lk3,发现存在临界纤维长度LC,溢流中含有较高含量的较长纤维,底流中含有较高含量的较短纤维。分析了分流比对相对分离指数的影响。　The author suggested that the relative separation index H（L） can be expressed as H（L）=exp（L^k1）-k2L^k3.There exists a critical fiber length.The content of fibers longer than the critical fiber length in the overflow is higher and the content fibers shorter than the critical fiber length in the underflow is higher.The effects of split ratio on relative separation index are studied.

关 键 词：水力旋流器 纤维筛分 评价分流比 相对分离指数
