The top pions ({pi}{sup 0,{+-}}) and the top Higgs (H{sub TC}) are the typical particles predicted by the topcolor-assisted technicolor (TC2) model and the observation of these particles can be regarded as the direct evidence of the TC2 model. In this paper, we study two pair production processes of these new particles, i.e., e{sup +}e{sup -}{yields}H{sub TC}{pi}{sup 0} and e{sup +}e{sup -}{yields}{pi}{sup +}{pi}{sup -}. The results show that the production rates are at the level of several fb for e{sup +}e{sup -}{yields}H{sub TC}{pi}{sup 0} and tens of fb for e{sup +}e{sup -}{yields}{pi}{sup +}{pi}{sup -}. These processes can produce the adequate distinct multijet final states and the standard model background can be efficiently reduced. So, with the high luminosity at the planned linear colliders, the top pions and top Higgs can be observable via these two pair production processes without question.
