The curve plotted in this way would meet the boundary conditions given and all the polar curves embodied the same wrapping angle. 这一方法不仅保证了绘制的型线有给定的边界条件,同时保证了各型线有相等的包角。
The cross air blow of spinning equipment, the spinning pack and the improvement of winding angle in take-up equipment were emphatically analysed. 重点分析了纺丝设备的侧吹风,纺丝组件以及在卷绕设备上卷绕包角上的改进。
