he mechanism to prohibit corrosion was different,adding Pb2+ and polyethylene glycol in the electrolyte.In the farmer case,a complex reaction occurred between Zn and Pb2+ and formed vast ballshaped complex ion whose center was Pb2+ and whose subordinate was Zn and when polyethylene glycol was added,polyethylene glycol was absorbed to the Zn surface and forms a thin films,so as to stop the dissolution of Zn.In this paper,the mechanism is fairy consistent with many experimental results.
