摘要
从数学上证明了上端固定,下端作圆周运动的弦振动是驻波。络纱时产生的退绕气圈也是这种形式的驻波。对气圈形状、节数和张力的研究应以弦振动理论为基础。
It has been proved mathematically, that the string vibration will forms standing waves if its Uper end is fixed while lower end moves round a circle. The study of the shapes, sections and tension of unwinding balloom must be based upon the theory of string vibration.
