Experimental results indicate that the effective absolute permeability coefficient increases greatly with the electric field strength increase in the low permeable natural core, but increase slowly in the high permeable natural core.

• 对于低渗透天然岩心 ；其有效绝对渗透率因数随电场强度增大而单调递增 ；且其值很大 ；而高渗透天然岩心的有效绝对渗透率因数提高的幅度较小 .
