【Abstract】 In this paper it is mainly analyzed theoretically the linear and non\|linear factors in the experiment of measuring electric potential by potentiometer and offered a method on how to avoid the non\|linear error,and also,introduced the criterion on how to distinguish linear and non\|linear ranges and presented the clear physical concept about the linear range of potentiometer.更多还原
