均匀扰动 meaning in English

homogeneous perturbation
isotropic turbulence

Numerical experiment shows that this heterogeneous disturbance arising from soil water content ' s spatial variability cannot be neglected when regional mean evaporation fluxis estimated
数值试验表明，这种因空间变率而引发的非均匀扰动项在估计区域平均通量时具有不可忽视的影响。
To demonstrate the heterogeneity of hydrological flux and the significant influence on regional evaporation , firstly , it is proved theoretically that because of soil water content ' s horizontal spatial variability ( heterogeneous distribution ) an additional heterogeneous disturbance which is equivalent to mesoscale flux is induced
首先从理论上推证出：由于土壤水分所存在的水平空间变率(非均匀分布，对网格区平均通量而言，可引发附加的量级与中尺度通量相当的非均匀扰动项。
