Abstract：
In the present paper a picture of the baryon-antibaryon system is proposed. If proton, neutron and A hyperon with spin 1/2 form the SU(6) basic particles, then the baryon-antibaryon system must be classified by the SU(6) group (It can be classified into pseudoscalar BB system and vector BB system). The spectrum of the BB system has two characteristics: The "Unitary energy band" and the "strangeness analogy state". In this paper the experimental spectrum of the Pp systemwith spin 1/2 and the calculation show that there exist the SU(6) "Unitary energy band" in the Pp system and exist the "strangeness analogy state" between the Pp system and other BB systems such as np system or BB systems which have strangeness S=±1.
