| 摘 要： | 用简单的几何模型计算限双激子体系的束缚能，得到二维双激子与单激子的束缚能比率随σ＝ｍｅ＾＊／ｍｈ＾＊从０．３２４到０．２２８之间变化，与前人的实验和理论结果符合较好。

| Abstract: | Using a model structure for a two dimensional biexciton,we calculated its binding energy.The ratio of the binding energy of a 2D biexciton to that of a 2D exciton is found to be from 0.324 to 0.228.The results agree fairly well with previous expermental and theoritical results. |
