摘要
对于实验中存在的某些加性误差,可以用差值法减小这种误差。文章阐述了差值法的原理。推导了电热法测热功当量实验中,用差值法减小加性误差的结果。讨论了用单摆测重力加速度时减小加性误差的问题。
In this paper the differential method is introduced to reduce some addition error in test. The principles of differential method are expounded. Results from a specific experiment are presented. It also discusses on reducing addition error when using single pendulum to measure the acceleration of gravity.
