中文摘要：

在二维空间中考虑了一类非线性Schroedinger方程组．在能量守恒及质量守恒的基础上，通过对解的极限行为的研究，建立了一系列解在原点的局部恒等式，得到了方程组的径向对称爆破解的集中性质．

英文摘要：

A coupled nonlinear Schroedinger equations is considered in 2-D space.Based upon the conservation of mass and energy, local identifies was established by the study of the limit behavior of the solutions, and concentration for the blow-up solutions with radially symmetry was obtained.
