Query: SUSY-QCD Effect on Top-Charm Associated Production at Linear Collider   We evaluate the contribution of SUSY-QCD to top-charm associated production
at next generation linear colliders. Our results show that the production cross
section of the process $e^+e^-\to t\bar c{or}\bar t c$ could be as large as 0.1
fb, which is larger than the prediction of the SM by a factor of $10^8$.
