truncation error

基本解釋

It is different from traditional concept that the concept dynamic roughness includes influence of model error, truncation error, observation error and so on.
此時的糙率與傳統(tǒng)的概念有明顯的不同，它包含了模型誤差，截斷誤差，觀測誤差等各方面的綜合影響。

截斷誤差
First, the paper introduces All Phase truncation considering all kinds of truncation situations, which can make the truncation error less.
