Inthispaper,byapplyingasimplifiedversionofLieb'sspin-reflection-positivitymethod,whichwasrecentlydevelopedbyoneofus[G.S.TianandJ.G.Wang,J.Phys.A:Math.Gen.35(2002)941],weinvestigatesomegeneralpropertiesoftheboeon-fermionHamiltonlan,whichhasbeenwidelyusedasaphenomenologicalmodeltodescribethereal-spacepairingofelectrons.Onamathematicallyrigorousbasis,weprovethatforeithernegativeorpositivecoupingV,whichrepresentsthespontaneousdecayandrecombinationprocessbetweenbosonandfermioninthemodel,thepairingenergyofelectronsisnonzero.Furthermore,wealsoshowthatthespin-excitationgapoftheboson-fermionHamiltonianisalwayslargerthanitschargedgap,aspredictedbythepre-palredelectrontheory.
