基于充液飞行器的简化模型，在状态空间中设计控制规律以约束状态至滑模。滑模通过在一个约化空间中求解最优控制问题获得，其解是角速度作为姿态变量的函数。
A control law, that constrains the state to follow the sliding mode in the state space, is designed on the basis of a nonlinear, simplified model of the completely liquid-filled spacecraft dynamics.
引入空间群消光规律，用计算机模拟电子衍射图，提出选取约化四边形的新方法。
Adopting the space-group extinction rule and simulating the electron diffraction pattern with computer, this paper proposed a new method for selecting the reduced quadrangle.
