动量矩方程 meaning in English

moment-of-momentum equation

Patterns which are based on experience and experiment and wasteful in time , nonguarantecable in quality . high production efficiently is then achieved . and the same time , this paper puts forward a relative control system , changes and realizes the adjustment of spinning speed and the fixed increasing the technology and application of stone balls , yielding better economic efficienly . in the end of this paper , there is an appendix of computation program edited by c language , the geometry parameters of stone balls
同时通过恒定总流的能量方程和动量矩方程，确定了风水球转速的计算方法，建立了相应的控制系统，改变了过去风水球转速、转向固定不变的状况，实现了对转速转向的调节，设计了转向控制系统和转速控制系统，提高了风水球的技术含量和可观赏性，从而获得更好的经济效益。
