In　practical　applications　of　graphene-based　electronic　devices,　they　may　have　some　pore　defects　under　energetic　particle　bombardment,　or　chemical　corrosion,　which　will　inevitably　affect　their　electrical　properties.　These　problems　have　recently　aroused　great　concern　and　interest.　In　this　paper,　we　systematically　study　the　influence　of　shape　(tripartite,　tetragonal　and　hexagonal)　of　hole　defect　on　the　electrical　property　of　zigzag　graphene　nanoribbon　(ZGNR).　The　results　show　that　the　influence　of　the　shape　of　the　pore　defects　on　the　conductance　and　current　characteristics　of　ZGNRs　is　significant,　whicl　may　result　from　electron　scattering　for　the　different　shapes　of　the　poredefect　boundary.　In　addition,　due　to　defects　in　suspension　adsorbed　hydrogen　or　nitrogen　atoms,　caused　by　defects　of　the　pore　shape　changes,　it　also　affects　the　electrical　properties　of　ZGNRs.　This　study　will　supply　valuable　theoretical　guidances　for　graphene-based　electronic　device　failure　analysis　and　the　design　of　the　graphene　pore　structure.
