Abstract
In this paper, (1) a kind of meaning of the BEC concept and the condition of the BEC formation of synopsis are introduced.(2) we demonstrate the possibility of BEC of an ideal Bose gas confined by one-and two-dimensional power-law traps. One-dimensional systems display BEC in traps that are more confined than parabolic: U(x)~xη, η2, Two-dimensional systems display BEC for any finite Value of η.
