In　this　paper,　we　first　prove　some　sufficient　conditions　for　the　biholomorphic　convex　mappings　on　the　Reinhardt　domain　DP　(pj　≥　2,　j　=　1,⋯　,n)　in　Cn.　From　these,　we　construct　some　concrete　examples　of　biholomorphic　convex　mappings　on　the　Reinhardt　domain　DP　(Pj　≥　2,　j　=　1,⋯,　n).　We　also　introduce　a　linear　operator　and　a　sub　class　of　biholomorphic　convex　mappings　for　the　purpose　of　constructing　some　biholomorphic　convex　mappings　on　DP　in　Cn.　Copyright　©　2009　Rocky　Mountain　Mathematics　Consortium.
