1. In this article, we preposed an improved method of median. filer on the basis of analysing the character of MTM and traditional filter method. 在分析MTM算法和传统平滑算法结构特点的基础上提出了一种改进的自适应中值滤波算法。
2. Based on the principle of flight of fan wing aircraft, realizing methods of VTOL are preposed by changing the Angle of attack and increasing chord length of the tail. 基于扇翼机的飞行原理,提出通过改变攻角以及增加尾部升力面弦长的方式提高气动效率,进而实现垂直升降的方法。
