两种落针法测量液体粘滞系数实验方法比较

Comparison of two experimental methods in drop-stitch measurements of the liquid viscosity coefficient

用一种新的霍尔传感器测量液体的粘滞系数,运用传统电子表和霍尔传感器测量粘滞系数进行比较.结果表明霍尔传感器测量液体的粘滞系数更好地消除了系统误差.这使学生实验更加方便,又提高了实验的准确性.

Using a new kind of Hall sensor to measure the liquid viscosity coefficient. Compared to the measurement of the liquid viscosity coefficient between traditional electronic watch and Hall sensor. The results show that the measurement of the liquid viscosity coefficient using the Hall sensor performed better in system error eliminating, facilitating the students＇ experiment, and improving the accuracy of the experiment.
