Positive electron and antiparticle are found.

A new interpret,based on the relative mass-energy relation and the antiparticle theory and CPT theorem by Dirac in the framework of relativity theory of the function Ψ of Klein-Gordon equation is given.

In the meantime, we can find the space time correspondence points of the positrons and the antiparticles.

This parper exptores the interaction force of antimatters, and gives the four types interaction force and its intensity through comparison of the particles with antiparticles.

This paper expounds material microcosmic composition of everyday world and three families of material world;introduces antiparticles,the antideuteros and the antihydroen atom are fanded;explores the possibility of producing antimatter when the cosmic tremendous explosion and discusses the riddle of huge explosion in Tunguska.

The compound fraction of target surface was gotten from the rate equation s of sputtering and the transport equations of reactive particles .

A method which is independent on the momentum picture is introduced to calcu-late the threshold energy of initial state particle and the maximum energy of final state particlein particle reactions.
