标题： Variations of helioseismic parameters due to magnetic field generated by a flux transport model

摘要： 太阳活动周期中，在对流底部发现了声速的变化，这可以用来约束太阳内部的磁场。 我们旨在检查由太阳发电机产生的磁场是否会导致通过日震学检测到的声速周期性变化。 通过使用巴布科克-利顿（BL）型通量传输发电机，获得了太阳内部磁场的基本配置。 我们通过同化由已建立的发电机产生的磁场来重构一维太阳模型，并检查了它们对结构变量的影响。 结果表明，发电机产生的磁场能够在太阳活动周期内引起对流层底部声速剖面的显著变化。 通过调整发电机模型的自由参数，这一理论预测的详细特征也与太阳活动周23期的日震学结果相似。 显示英文摘要

摘要： The change of sound speed has been found at the base of the convection during the solar cycles, which can be used to constrain the solar internal magnetic field. We aim to check whether the magnetic field generated by the solar dynamo can lead to the cyclic variation of the sound speed detected through helioseismology. The basic configuration of magnetic field in the solar interior was obtained by using a Babcock-Leighton (BL) type flux transport dynamo. We reconstructed one-dimensional solar models by assimilating magnetic field generated by an established dynamo and examined their influences on the structural variables. The results show that magnetic field generated by the dynamo is able to cause noticeable change of the sound speed profile at the base of the convective zone during a solar cycle. Detailed features of this theoretical prediction are also similar to those of the helioseismic results in solar cycle 23 by adjusting the free parameters of the dynamo model.
