误差表示准则 有效数字 微小误差
This paper, based on the tiny error rule (TER) in algebraic sum method, derived the criterion for correctly expressing errors with significant digit, for the first time. Then, according to the criterion, an important conclusion is further reached, namely, any error only needs to keep three significant digits at most, or it is meaningless. Thus, this paper further perfected the theory of error, and so, it is of great significance for accurately processing all measurement data.
