摘要
Acoustic mode frequencies, with degree up to 900, observed by Michelson Doppler Imager (MDI) from 1995 to 2005 were analyzed to determine if there are any changes in the near-surface layers of the solar structure with the solar cycle. The inclusion of high-degree modes allowed the determination of the sound speed up to 0.993R(circle dot).
