摘要：
A perturbation method is developed for calculating the effect on the frequencies of solar global oscillations of changes in the chromosphere. We show that the frequency perturbation depends on the subphotospheric structure of the solar model only through the mode inertia (or mode mass). The effects of changing the chromosphere can first be calculated independently of any particular model of the solar interior; and the frequency perturbations for any given model then obtained by scaling with mode inertia. In particular we apply the method to changes in chromospheric magnetic field.
