Bionic　super-hydrophobic　surface　has　a　multiple　micro-nano-binary　structure　(MNBS)　similar　to　the　microstructure　shown　on　a　lotus　leaf.　This　kind　of　the　surfaces　has　a　contact　angle　of　water　greater　than　150°　and　a　roll　angle　smaller　than　5°.　In　this　paper,　the　frost　deposition　phenomena　on　a　bionic　super-hydrophobic　surface　were　observed.　The　surface　has　a　159°　contact　angle　and　is　made　of　many　micro　bumps.　The　formation　of　water　droplets,　the　droplet　freezing　process,　the　formation　of　initial　frost　crystals　and　the　frost　layer　structure　on　a　cold　bionic　super-hydrophobic　surface　under　natural　convection　conditions　were　closely　observed.　The　frost　layer　structure　on　the　super-hydrophobic　surface　shows　remarkable　differences　to　that　on　a　plain　copper　surface:　The　structure　is　weaker,　looser,　thin　and　easy　to　be　removed　and　most　importantly,　it　is　of　a　very　special　pattern,　a　pattern　similar　to　chrysanthemum,　a　frost　layer　structure　that　has　not　been　reported　before　as　far　as　the　present　authors　could　know.　The　experimental　results　also　show　that　the　super-hydrophobic　surface　has　a　strong　ability　to　restrain　frost　growth.　The　frost　deposition　on　this　bionic　surface　was　delayed　for　55　min　compared　with　the　plain　copper　surface　under　the　conditions　of　a　cold　plate　temperature　-10.1°C,　air　temperature　18.4°C　and　relative　humidity　40%.　A　theoretical　analysis　was　also　presented　to　explain　the　observed　phenomena.
