The minimum supersymmetric standard model (MSSM) without R-parity through various lepton-number violations is investigated systematically. All kinds of possible mixing in the model are formulated precisely. The remarkable issue that the lightest `Higgs' H10 may be heavier than the weak-boson Z at tree level is kept, as the special R-parity violation MSSM where only bilinear violation of the lepton numbers is allowed. It is also shown explicitly that there is a freedom U(n+1) (n is the number of the broken lepton-numbers) in re-defining the lepton and Higgs superfields. Feynman rules relevant to the R-parity violations are given precisely in 't Hooft-Feynman gauge. With further assumptions and concerning all available experimental constraints, spectrum for interest sectors is computed numerically.
