摘要：

The coordinate-momentum double distribution function rho((r) over right arrow,(p) over right arrow)d(3)rd(3)p is calculated in the local density approximation for bosons with positive scattering length a in a trap. The calculation is valid to the first order of a. To clarify the meaning of the result, it is compared for a special case with the double distribution function rho(w)d(3)rd(3)p of Wigner.
