Abstract: Recently the theoretical studies and the experimental surveys have indicated that new phenomena can emerge under the extreme conditions of high temperature,high energy and high density．For example,there is the problem about the fate of the standard model,the problem of baryon number and leptonic number violation when temperature is higher than Planck mass (1019　GeV),and the problem of mutual transformation of common baryon matter and quark-gluon plasmon when temperature is high．Based on the writers' previous achievements in research,sone viewpoints are presented and some conclusions are reached．It is hopeful that the discussion can give an impetus to the research of particle-astrophysics．

Key words: early universe nucleons, super-micro-black hole, (B+L) violation, quark-gluon plasmon
