用DIS系统验证玻意耳定律实验的误差分析

Error analysis on the experiment of validating Boyle law using DIS system

在验证玻意耳定律实验时,采用压力传感器采集数据,虽然测量的精度提高了,但实验数据拟合直线不经过原点.分析误差产生的原因,认为该情况是由于传感器管道中留有的少量气体引起的,并对实验数据进行了修正,修正后的拟合直线通过原点,较好地验证了玻意耳定律.

In order to increase the measuring precision, the pressure transducer is used to collect data in the experiment of validating Boyle law, but the fitting curve does not pass the origin of the coordinate system, which is not in accordance with the Boyle law. The experiment error comes from the gas in the pipe of the pressure transducer. After correction, the results are in good accordance with Boyle law.
