Query: $H_{TC}\Pi^0$ and $\Pi^+\Pi^-$ pair productions at the planned $e^ + e^
  -$ colliders in the topcolor-assisted technicolor model   The top-pions($\Pi^{0,\pm}$) and the top-Higgs($H_{TC}$) 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., $e^ + e^ - \to H_{TC}\Pi^0$ and $e^+e^-\to \Pi^+\Pi^-$. The
results show that the production rates are at the level of serval fb for $e^ +
e^ - \to H_{TC}\Pi^0$ and tens fb for $e^+e^-\to \Pi^+\Pi^-$. These processes
can produce the adequate distinct multi-jet final states and the SM 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 double.
