利用密度泛函理论中的B3LYP方法，选择LANL2DZ双Zeta基组，并考虑极化函数 ，对Ti_3P_6~+团簇可能存在的几何构型进行了理论计算研究，得到了Ti_3P_6~+具 有C_s对称性的最稳定构型，所得构型很好地说明了激光光解的实验结果。

The possible geometrical structures and relative stability of Ti_3P_6~+ cluster are explored by means of density functional theory (DFT) calculations. The effects of polarization functions and electron correlation are included in these calculations. The results show that the most stable structure of Ti_3P_6~+ belongs to the C_s point group. The properties of Ti_3P_6~+ is in good agreement with the experimental results.
