X-ray emission,as one of the important consequential results from ion-atom collision,carries the important information of several inner-shell processes as primary ionization,vacancy decay and intra-atomic excitation,which provides a valid method to investigate the particle properties and the complex interaction *** our previous work,such multiple ionization of projectile has been observed and the effect of incident energy was verified ***,we would like to present the further plan in which a special attention is going to focus on the dependence of multiple ionization on projectile charge state and target atomic number.

为了保证机器人在任意的抓取位姿皆能够完成3种形状轴孔零件的装配任务,提出了一种利用力传感器实现主从双臂协调运动的轴孔装配策略。详细描述了该策略在3个不同阶段的控制方法,在理论上保证了该策略的可行性。搭建了实验平台,针对3种不同形状的零件,分别采用4组不同的抓取位姿进行了实验。实验结果表明:由于零件形状的不同使得双臂在Z轴方向的调整角度不同,导致了装配任务耗时的差异性;对任意形状的零件以任意的位姿抓取,系统均能够在最短的时间内搜索出准确的装配位姿,以完成各种复杂形状轴孔零件的装配任务,验证了所提出的主从双臂协调下的轴孔装配策略的可行性和有效性。
