摘要

<正> The Bose-Einstein condensates(BEC) of trapped atomic gases with internal degrees of freedom are new forms of macroscopically coherent matter. These forms of matter exhibit rich quantum structures and provide new opportunity to examine the quantum many-body theory in detail way. An essential feature of a spinor BEC is that two or more hyperfine states have almost the same energy and the spin degrees of freedom become
