在局部连通集上定义了连通b -凸函数；在关于弧的右上导数的基础上，定义了连通- B伪凸，连通b -拟凸函数，推广了B -凸函数。

Then it expands the B-vex functions by defining connected pseudo B-vex and connected quasi B-vex functions in terms of right upper derivative with respect to an arc.

在轨迹处理中，提出基于弦长和弧长关系的伪轨迹处理方法，得到合理的运动轨迹。

A pseudo-trajectory processing method based on the relationship between chord lengths and arc lengths is proposed to obtain reasonable trajectories.
