对数方程 meaning in Chinese

logarithmic equation

6 . the tortuosity factor ( f ) was an important geometric parameter , which affected ion ' s diffusion and varied at different levels of water content
半对数方程（ f a blnw ）是拟合土壤曲折系数什）与含水量（ w ）的最佳关系式。
4 . on soil profile , the distribution of kc1 applied at soil surface could be described by equations of c = a + blnz , where c was the concentration of the diffusing ion ( mg / kg ) of soil , z the soil depth , a and b simulated parameters
可用半对数方程二a blnz ）拟合两种离于在上壤剖面中扩散的动态过程，式中c为养分离于含量沁叭g ）为土层深度仁）， c 、 b为拟合参数。
