    It is found by measuring the low-field conductivity of segments of TaS3 single crystals that a current pulse equal to or larger than threshold for sliding charge-density-wave (CDW) conduction permanently destroys the inversion symmetry of the sample. The segments are limited at one end by the usual silver paint contacts which strongly perturb the motion of CDW's while at the other end a special weakly perturbing contact is applied. The low-field resistance of the segments depends on whether the last sliding CDW current pulse enters or exists the strongly perturbing contact. The results are interpreted as a direct confirmation of current-induced remanent CDW polarization recently reported by Janossy, Mihaly, and Kriza.
