logarithmic formula造句

in pattern, the velocity distribution still corresponds with the logarithmic formula except that the value of k is smaller than that in non-particle flows
所谓型分布，是指沿整个水深仍可用对数公式表达，但k值变小的分布。
as for pattern, the logarithmic formula is also effective either in core region or in surface layer, and the values of k in both cases become smaller but differ to each other
型分布则是指主流区仍可用对数公式表达，且k值变小；在近底区亦近似符合对数律，但两区的k值有所不同。
