摘　　要：基于近年来实验发现的轨道激发态介子,分别利用雷吉轨迹的线性和方根形式,计算了实验数据丰富的1^(1)S_(0)、1^(3)S_(1)和1^(3)P_(2)介子多重态中各不同介子成分雷吉轨迹的质量谱,根据两种轨迹的计算结果与现有的实验数据对比分析发现,线性雷吉轨迹描述介子谱更合理。实验上更多高自旋介子态的发现将会验证这一结论。Based on the orbital excited mesons discovered experimentally in recent years,in the framework of the quasi-linear Regge trajectory and square-root Regge trajectory,the masses of the states lying on the well established 1^(1)S_(0),1^(3)S_(1),and 1^(3)P_(2)trajectories are estimated.Comparison of the results given by the two trajectories with the existing experimental data illustrates that it is more reasonable to describe the existing meson spectrum with the quasilinear trajectory.This conclusion will be confirmed by the high-spin meson states discovered experimentally.
