说明：  陀螺运动的仿真程序，动力学仿真和动画同时表示 陀螺在重力下以适当的初始速度落地的仿真结果(Gyro movement simulation program, dynamic simulation and animation at the same time that the top of the gravity of the initial velocity to the appropriate landing simulation results)

对于卫星系统的优化，目前比较前沿的是基于多学科优化(MDO)的方法，文中重点对此方法进行了介绍。(For the satellite system optimization, more cutting edge is based on the current multi-disciplinary optimization (MDO) methods, the paper focus on this method were introduced.)

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)
