摘要
用一个星系相互作用数值模拟的综合三体模型，研究椭圆星系是否由盘星系合并而成。结果表明，主要取决于星系的盘面和星系运行轨道面的夹角。如果夹角不等于零，盘星系的相互作用是可能形成椭圆星系的，否则还是盘星系。
perfect three-body model is used in the numerical simulation of interacting galaxies for studying whether merging disk galaxies make elliptical galaxy.It is showed by simulation that there are two possibilities:If the angle between disk plane and orbital plane of both galaxies do not equal to zero,it is possible that merging galaxies form a elliptical galaxy:if the angle equal to zero the merging galaxies will form a new disk galaxy.
