- W2363229367 abstract "We improve and debug traditional pendulum,utilize the consistency of the starting state of pendulum ball manipulated by electromagnet to adjust the photoelectric door under the lowest equilibrium position of the swinging ball,measure the accurate vibration cycle of the pendulum ball.By analyzing experiment principle and uncertainty we introduce curve estimation of SPSS to analyze experiment data,and obtain the calibration cure between the effective length of pendulum and square of the pendulum period,verify there exist linear relationship between the compound of effective pendulum length and square of the vibration cycle.So,we calibrate the gravity acceleration in the end,analyze and evaluate the measurement data and the experiment result with the confidence probability of 95% uncertainty in order to obtain the more reasonable experiment result." @default.
