A general dynamically permissible velocity field for plane flow is set up in the paper. The force and energy parameters for extrusion (or drawing) are analyzed, and the optimum draw Angle is obtained.

本文建立了平面流动较为一般化的动可容速度场，分析了平面挤压(拉拔)的力能参数，获得了最佳凹模锥角。

So if we do this and we form the molecule ammonia, let's switch to a clicker question, and have you tell me what the bond angle - is going to be in ammonia -- HNH Actually, let me draw it on the board as you look -- actually, can you put the class notes on, since you don't actually have your notes to refer to.

如果这样做的话，我们就可以形成氨分子，让我们来做一个课堂练习,你们告诉我氨分子中的键角是多少-,键角，the，h，n，h，bond，angle。,实际上让我在黑板上画出它来，这样你们可以看到实际上-,你能把课堂讲义放出来吗，因为你们没有讲义可以参考。
