infiltration of neutrophil cells was seen.───可见较多中性白细胞浸润。
If the infiltration intensity is less then the saturated permeability coefficient, the surface soil finally reaches to an unsaturated infiltration stage instead of saturated infiltration stage.───当降雨强度小于土体的饱和渗透系数时，表层土体达不到饱和状态，最终的稳定入渗只能达到一个非饱和入渗状态。
The research on dolomite genesis is in postulation stage at present, which includes five models of vaporization, infiltration and circumfluence, sea water, mixing water and buried dolomitization.───白云岩成因的研究目前还处于假说阶段，主要包括蒸发、渗透回流、海水、混合水以及埋藏白云岩化作用五种模式。
If the infiltration intensity is less then the saturated permeability coefficient, the surface soil finally reaches to an unsaturated infiltration stage instead of saturated infiltration stage.
