摘要：
A new method of testing the validity of the static EDL theory as applied to streaming potential was developed. By measuring the electrical potential downstream along the channel surface,one may determine the validity of the static EDL theory with the introduction of a flow field. Experimental results suggest that the direct applying of the static EDL theory to streaming potential measurement may cause great discrepancy which was usually to be ascribed to the surface conductance.
