    摘要: We review spiral density-wave theory and its realtionship to the disordered appearance of population I objects in some disk galaxies. We discuss mechanisms proposed for the formation of (a) feathers by gravitational instability behind galactic shocks, (b) branches by the action of ultraharmonic resonances, (c) spurs by reflection of leading waves off sharp features induced by nonlinear dredging, and (d) flocculence by the chaos produced from overlapping resonances. We conclude that disorder arises in spiral galaxies not so much from disorderly causes as from too sensitive a response of the interstellar medium to an orderly but nonlinear spiral gravitational field.
