计算并讨论了核对称性能量斜率对中子星非径向振荡f模的影响。基于实验和理论分析所限定的对称性能量斜率的保守范围，得到了中子星星中f模引力辐射的频率和阻尼时间的限制。研究还表明，较高的对称能量斜率对应于较小的频率和较长的阻尼时间。同时，给出了一组新的参数，以反映标度频率和阻尼时间的普适性质。
The effect of the nuclear symmetry energy slope on the non-radial oscillation f-modes in neutron stars is calculated and discussed. Based on a conservative range of the symmetry energy slope constrained by the experiment and theoretical analysis, a constraint on the frequency and damping time of the gravitational radiation from the f-mode in neutron star is obtained. It is also shown that a higher symmetry energy slope corresponds with a smaller frequency and a longer damping time. Meanwhile, a new set of parameters is given to present the universal properties of the scaled frequency and damping time.
