摘要：
We propose a rational quantum deformed nonlocal currents in the homogeneous space SU(2)(k)/U(1), and in terms of it and a free boson field a representation for the Drinfeld currents of Yangian double at a general level k = c is obtained. In the classical limit (h) over bar --> 0, the quantum nonlocal currents become SU(2)(k) parafermion, and the realization of Yangian double becomes the parafermion realization of SU(2)(k) current algebra.
