用气轨系统与Spss标定物体的惯性质量

摘要

通过对气轨系统的改进与调试，用气垫导轨测量物体做简谐振动的周期，由实验原理及其不确定度的分析，结合测量数据，应用Spss软件分析给出周期的平方与其惯性质量的定标曲线，验证了物体在气垫导轨上做简谐振动周期的平方与其惯性质量存在线性关系，进一步验证了物体的惯性质量与其引力质量相等的关系。%　　Thepapermeasuresthecycleofsimpleharmonicmotionwiththemethodofgas - trackby improvinggas - tracksystem.Thepaperhasanalyzedthecalibrationcurvebetweenthesquareofthe cycleanditsinertialmassaccordingtoexperimentprincipleanduncertaintyanalysis,combinedwith measurementdata.Andthepapervalidatestherelationshipbetweenthesquareofthecycleofobjects performingsimpleharmonicmotiononthegas - trackandinertialmass,whichfurthervalidatesthatin -ertialmassofobjectisequaltoitsgravitationalmass.
