| 摘 要： | By means of infinite-dimensional Kac-Moody-Virasoro symmetry group transformation, rich localized (3 1)-dimensional excitations such as dromions, ring-shape and bubble-like excitations are obtained for a matrix systemwhich is produced by extending the Lax pair of the celebrated self-dual Yang-Mills field. Abundant (3 1)-dimensional localized excitations can also be found in other types of nonlinear systems.
