| 摘 要： | 设计了由改进的弹射架和定位释放器组成的等速发射装置,实现了气垫导轨实验中滑块的等速发射,并可通过控制滑块初始位置使滑块获得预期发射速度.分析表明滑块发射所获得的速度和初始位置间的关系为近似的线性关系,这一结论和实验结果完全符合.

| Abstract: | The catapult device at identical velocity is designed,which is composed of improved catapult rack and positioning release device.It can catapult glider at identical velocity in air track experiment.And through controlling the initial position,the glider can be catapulted at definite velocity.Analysis indicates that the relation between velocity and initial position of the glider catapult is approximately linear.It is accorded with the experiment result. |
