由于鼓形齿式联轴器角向补偿大于直齿式联轴器。
Drum gear coupling due to the compensation Angle is greater than straight-tooth coupling.
当我们谈到角向节点时,一个轨道的,角向节点数等于l。
And when we talk about angular nodes, the number of angular nodes we have in an orbital is going to be equal to l.
天然气火炬削减的部分,但是,角向磨光机将作整洁工作。
Gas torch to cut the parts out, but the Angle grinder will make a neater job.
But because there's this lone pair here, it's pushing down on the other bonds, 5° so we end up with an angle of less than 109 . 5 degrees.
但因为这里有孤对,它会把其它键向下压,所以键角会小于109。
So, let me get a little bit more specific about what we mean by nodal plane and where the idea of nodal plane comes from, and nodal planes arise from any place you have angular nodes.
关于节面的意义,或者节面概念的起源,让我们讲的更具体一点,节面起源于角向节点。
You can go ahead and use that equation, or you could figure it out every time, because if you know the total number of nodes, and you know the angular node number, then you know how many nodes you're going to have left.
你们可以直接用这个方程,或者每次都自己算出来,因为如果你们知道了总的节点数,又知道角向节点数,就知道剩下的节点数是多少。
