图1显示了控制倾斜上唇喷嘴流出角和收缩系数的主要变量。 图中给出的信息。2和3是针对非粘性理想流体推导的，可用于预测水中稀释纤维悬浮液的高速流出，前提是重力和表面张力的影响很小，且流动在几倍于切片开口b的距离内畅通无阻。

The primary variables which govern the angle of outflow and contraction coefficient for a nozzle with inclined upper lip are shown in Fig. 1. Information given in Figs. 2 and 3 was derived for a nonviscous, ideal fluid and can be used to predict high velocity outflows of dilute fiber suspensions in water, provided that the effects of gravity and surface tension are small and the flow is unobstructed for a distance of several times the slice opening b.
