| 摘 要： | 现行的碰撞实验多在气垫导轨上进行,并利用橡皮筋发射滑块,由于橡皮筋容易老化问题难于解决,所以设计了可调节、可显示弹射能量的弹簧枪,用弹簧枪代替橡皮筋,从而可以实现多种被弹射物体的定速发射和同速发射.

| Abstract: | Now the collision experiment is usually carried out on air track,using elastic string to launch the slider.Problems caused by the the aging of the elastic string is difficult to solve.An alternative designs,using a spring gun instead of the elastic string,is presented in this work,which can adjust the launching energy and launch the slider at identical velocity. |
