Trajectory Reconstruction of Human Upper Extremity when Moving on Horizontal Plane

人体 上肢在 水平 面上运动时的轨迹重构

HORIZONTAL STRESSES IN THE UPPER LITHOSPHERE high horizontal geo-stress and low vertical geo-stress ; This paper mainly studied the change principle of the principal stresses and equivalent stresses on the horizontal plane fracture and near the wellbore .

重点研究了 水平裂缝 面 上及井眼附近的主应力和等效应力的应力等值线变化规律。
