摘要：
The thermodynamic quantities of a kind of (p, q)-deformed ideal Bose gas are derived by means of the statistical distribution function. It is shown that the entropy and the heat capacity of the system are discontinuous at the critical point. Therefore, the Bose-Einstein condensation of such a system is a second-order phase transition. When p, q --> 1, all the results obtained here are the same as those for the usual ideal Bose gas.
