利用光电计数器研究弹簧振子的周期——知识扩展

Using the Photoelectric Counter to Study the Period of the Spring Oscillator

在气垫导轨上测量弹簧振子的周期是中学物理中的重要实验,实验一般采用一个光电门和一个挡光片测量弹簧振子的周期,实验方法较单一,实验过程容易出现错误,为此,文章提供了几种不同的光电门和挡光片的组合下弹簧振子周期的计算方法,解决了实验测量中的问题,培养了学生的发散思维,锻炼了学生解决问题的能力.

Measuring the period of the spring oscillator on the air-cushion guide is an important experiment in middle school physics.The experiment generally uses a photoelectric gate and a light-block to measure the period of the spring oscillator.The experimental method is relatively simple,and the experiment process is prone to errors.The article provides several calculation methods for the spring oscillator period under the combination of different photogates and light barriers,solves the problems in the experimental measurement,cultivates the students'divergent thinking,and exercises the students'ability to solve problems.
