By using statistical physics method,some physical quantities for Bose Einstein condensation of an ideal Bose gas trapped by a harmonic potential are derived through theoretical calculation.It is found that the condensation is related closely with the shape of the potential.The critical temperature T C and the ground state fraction N 0/N obtained from the calculation are conformable to the experiment results quite well.These researches have contributed to a better understanding for this new substantial state.
