本文研究了等离子体中冷离子质量界面中离子-声孤子的传播过程。结果表明，两种情况下的透射波行为相似，入射孤子在从重离子区到轻离子区穿过质量界面时可能发生裂变。研究还发现，密度不连续面在入射孤子通过后向其传播方向移动。
The propgation of an ion-acoustic soliton through a mass interface of cold ions in a plasma is investigated both for a discontinuous change and for a gradual change. It is shown that the behaviors of transmitted waves are similar for both cases and an incident soliton may fission when it passes through the mass interface from the region of heavy ions to that of lighter ones. It is also found that the plane of density discontinuity moves towards the propagation direction of the incident soliton after its passing.
