中文摘要：

发丝滴头出流流量与工作压力成正比，与发丝微管长度成反比，与发丝微管缠绕直径成正比，并分析了各影响因素与出流量之间的关系。根据试验分析结果，得出了发丝滴头新的出流公式，经实测验证，该公式具有较高的应用价值。

英文摘要：

A free-flowing experiment of microtube was carried out in the laboratory. The results show that the discharge of microtube was positive to the operating pressure and the winding diameter. At the same time, it was negative to the microtube length. The relations between influence factors and discharge were analyzed too. A new flow formula of microtube flux was given. Some applications have proved that the new formula has higher practical value.
