As a result of error distribution\\\'s non-uniqueness, draws out to the standard deviation understanding again, by about standard deviation reflected that the erroneous zero rank value two side the variation targets, the application unimodal distribution fits the error distribution, the goal is: By approaches the rationality which under the enhancement goodness of fit\\\'s premise determines to the error.

从文章的上下文感觉此标准值似乎是人为规定的，并不受实测数据本身分布的影响，不具有客观性。个人认为：研究在实际中实测数据相对于均值的分布更有意义。按照作者的观点，误差的分布都是单峰的，除了正态分布这种对称分布外，作者认为还有不对称的偏峰分布。因此研究这种偏峰分布模型可能更有意义。
