With the linear and angular momentum conversation, the state equation is established for the system control design. 该方法以系统动量和动量矩守恒关系为基础,建立了控制系统设计所需系统状态方程;
By using the pseudo angular momentum method, the radial equation for bound state of Kepler's problem is solved and the analytic expression for eigenstate is derived. 用赝角动量方法直接求解球坐标下束缚态开普勒径向方程。
For given orbital angular momentum states, we discover a complete set of independent base-functions, which are homogeneous polynomials in the components of the coordinate vectors and satisfy the Laplace equation. 对于确定的轨道角动量状态,找到了一组完备且独立的角动量本征函数基,它们是坐标分量的齐次多项式,且满足Laplace方程。
