类太阳振荡的标度关系提供了太阳中随机低阶振荡模式的特征的翻译，以预测具有对流外层的其他恒星中类太阳振荡的特征。这一预测是基于它们的恒星质量、半径和有效温度。随着时间的推移，原来的标度关系已经从预测类太阳振荡的特征逆转为推导恒星参数。已提议更新比例关系及其参考值，以适应因其使用变化而提出的不同要求。在这篇综述中，提出了通过类太阳振荡的标度关系来提高恒星参数估计精度的建议，并讨论了不同方法的利弊。
The scaling relations for solar-like oscillations provide a translation of the features of the stochastic low-degree modes of oscillation in the Sun to predict the features of solar-like oscillations in other stars with convective outer layers. This prediction is based on their stellar mass, radius, and effective temperature. Over time, the original scaling relations have been reversed in their use from predicting features of solar-like oscillations to deriving stellar parameters. Updates to the scaling relations as well as their reference values have been proposed to accommodate for the different requirements set by the change in their use. In this review the suggestions for improving the accuracy of the estimates of stellar parameters through the scaling relations for solar-like oscillations are presented together with a discussion of pros and cons of different approaches.
