By using the Lie group theory of differential geometry and Pontryagin's maximum principle, it is pointed out that the mobile CRS robot on surface is controllable, and the necessary conditions and the structure equations of extremal trajectories are proposed.

为了解决曲面上移动CRS机器人的路径规划问题，在曲面上建立了机器人的动态模型，利用微分几何的李群理论和庞特里亚金最大值原理，证明了曲面上CRS机器人是可控的，并给出了机器人的最小时间控制的必要条件和结构方程。

I think Haiwang regarded the land of the lotus and itself; He abandoned the details of lotus and focused on the object-oriented structure and only organic color contrast (such as the use of a lot of black); He considered only Light color with the seasons and the geometric structure of the landscape. It's different from the only source style and the natural tendency of Impressionism . It has more spirits with the traditional Chinese culture and the aesthetic value.

我想这与李海旺把荷花与生长它的大地联系起来描绘有关系；与他舍弃了荷花的细节，只注重对象的有机的结构和色彩的单纯对比有关系；也与他只考虑光色的季节和几何化的风景构造，也不同于印象派只重光源色的自然主义倾向而获得了与中国传统文化相通的审美价值。
