And in terms of radial nodes, we have 2 minus 1 minus 0, so what we have is one radial node.
对于径向节点，我们有2减去1减去0，所以有一个径向节点。
Yup, so one total node, 2 minus 1 is 1, and that means since l is equal to 1, we have one angular nodes, and that leaves us with how many radial nodes?
一个节点，2减去1等于1,因为l等于1,我们有一个角向节点，那剩下径向节点有多少个呢？
And in terms of radial nodes, we expect to see one node.
对于径向节点，应该有1个。
The node axial force and radial force decreased with the time increased and the change rate of the node stress at the center was less than that at the circumference.
节点轴向力、径向力均随时间的增加而减小，而且节点应力变化速率在中心区域小于圆周处。
