为了理解X（3872）的结构，我们研究了谐振子核态与D和D +D*−分子态的耦合效应. X（3872）的结构中约有9%为粲正离子，75%为等标分子，16%为等矢量分子，这很好地解释了X（3872）的观测性质.
In order to understand the structure of the X(3872) the effects of thecharmonium core state coupling to theandD+D*−molecule states are studied. The obtained structure of the X(3872) is about 9 % ofcharmonium, 75 % of the isoscalarmolecule and 16 % of the isovectormolecule which explains observed properties of the X(3872) well.
