Several diffrent but mutual-related models of the projective plane in this thesis reveal its structure and imagins its entire form,and had shown the whole nature-one side through the relations of the projective plane and Mobius tie.
本文给出射影平面的几个不同但是互相联系的模型 ,借以揭示射影平面的结构 ,想象射影平面的整体形状 ,并通过射影平面与莫比乌斯带的关系来了解射影平面的一个整体性质———单侧性。
Considering that in some cases we can focus the discussion on one side of a pair of solution,the one side stability and one side asymptotical stability criterion theorem is obtained by modifying the conditions of Liapunov theorem.
针对Liapunov稳定性定理中要求在平衡原点某邻域内满足一定的条件 ,考虑到平面系统的平衡点可以只在通过它的一对解的一侧讨论 ,经过一些条件的修改 ,得出了平衡点的单侧稳定性和渐近稳定性的判定定理 ,并给出证明过
