A superconductor/normal conductor potential probe pair was used to measure differences between the time-averaged electrochemical potentials <..mu../sub p/> of Cooper pairs and <..mu..> of quasiparticle excitations caused by a phase-slip center in several experimental situations. The results can only be understood by assuming that at a larger distance from the phase-slip center <..mu..> differs from the proposal of Skocpol, Beasley, and Tinkham by showing a ''swinging over'' or ''swinging below'' <..mu..>. We propose a modified slope of <..mu..> as a function of site. Possible explanations are discussed. The multiple-contact samples used also allow the study of the influence of phase-slip centers already present on the relaxation of nonequilibrium quasiparticles.
