Abstract：
The strong CP violation,the PQ mechanism and the axions in the standard model are discussed.The model of techniaxion is established.The mass and the lifetime of techniaxion,the coupling for techniaxion with other matters are obtained.The constraints on the properties of techniaxion from astrophysical and cosmological considerations are discussed.An axion physical state should exist in the cosmic rays.
