Basing on the Thomas-Fermi approximation or local density approximation(LDA) and the principle of the constancy of chemical potential in equilibrium,we calculate thermodynamic quantities of q-Bose gas,which include the critical temperature of BEC,the ground fraction of BEC,the total energy and the special heat of BEC.

Thermodynamic properties of a weakly interacting Bose gas in a weak magnetic field;

The influence of weak interaction on thermodynamic properties and the stability of imperfect Bose gas;

Vortex solution of weak interacting Bose gases;

Relationship of the Gaussian width of Bose-condensed gas and the intensity of ID-optical lattices potential;

Interference of Bose-condensed gas in a 1D optical lattice;

A solution to the ground and single vortex states of Bose-condensed gas in an axially symmetric harmonic trap;

The general expressiones of energy and heat capacity of n-dimensional ideal Bose gas with differnet eneregy-momentum relations are obtained at temperature T>T C and T<T C .

By using the generalized Bose-Einstein distribution function,Bose-Einstein condensation of a generalized Bose gases trapped in a generic power-law potential in the two dimensional space is investigated.
