A simple phenomenological model of the structure of an inhomogeneous quantum fluid is proposed. As examples of the application of the model the structure of the free surface of He II and the structure of the negative-ion bubble in He II are investigated. The free-surface structure compares well with the results of a more elaborate microscopic calculation. Questions concerning the effect of surface curvature and "tightening" of the bubble surface are examined.
