摘要: The effects of ultraviolet irradiation on small but finite amplitude dust-acoustic solitons, are studied by the reductive perturbation method. self-consistent dust charge variation is taken into account. It shown that can significantly lower magnitude negative charge, and even make grains charged positively. With growth phase velocity width solitary wave increase, whereas its decreases. related physical mechanism discussed.
