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。The paper measures the cycle of simple harmonic motion with the method of gas-track by improving gas-track system. The paper has analyzed the calibration curve between the square of the cycle and its inertial mass according to experiment principle and uncertainty analysis, combined with measurement data. And the paper validates the relationship between the square of the cycle of objects performing simple harmonic motion on the gas-track and inertial mass,which further validates that in- ertial mass of object is equal to its gravitational mass.
