【摘要】 通过对传统实验仪器和测量方法的改造,利用PASCO系统转动传感器测量得到单摆角位移与时间的关系,并使用Science Workshop高功能的数据处理软件DataStudio进行实验数据智能获取,以及MathWorks多功能的数值计算软件Matlab进行数据点的最小二乘法拟合,进而实现对重力加速度的测量,结果表明实验测量值接近公认值.更多还原

【Abstract】 The traditional experimental instrument and measurement method were improved by using the PASCO system rotation sensor to realize real-time measurement of angular velocity and angular displacement of the pendulum,and using Science Workshop’s high performance data processing software Datastudio and MathWorks’ s multi-function numerical calculation software Matlab.The gravity acceleration was accurately measured,the measured value was very close to the accepted value.更多还原
