摘要：

A new damping mechanism of condensate collective modes due to collisions with thermal cloud was calculated at finite temperatures. The condensate growth was supported by lack of diffusive equilibrium between condensate and thermal cloud. The explicit calculations of the damping mechanisms for the trapped gas in the collisionless regime was analyzed.
