Analysis of Helioseismic Data and Inversion for Solar Structure and the Excitation Process

地球物理数据分析技术将用于日震数据分析的类似问题，特别是对全球振荡台网组数据的分析。美国国家科学基金会（National Science Foundation）的一项重大项目是计划测量分布在地球周围的六个地点的太阳振荡。对振动频率的分析，就像对钟的振动频率的分析一样，将产生关于太阳内部的新信息，这是其他任何方法都无法获得的。但是现有的这类有限的数据已经表明，很难将这些数据转化为有关太阳内部的信息。这项拨款的研究人员将把已经高度发达的解释地球地震数据的技术应用于太阳数据。

Geophysical data analysis techniques are to be brought to bear on similar problems of the analysis of helioseismic data, with a particular view to the analysis of Global Oscillation Network Group data. A major project of the National Science Foundation is the planned measurement of solar oscillations from six sites spread around the Earth. The analysis of the oscillation frequencies, like those of a bell, will yield new information about the interior of the Sun not available by any other means. But existing limited data of this kind have already shown that it is difficult to transform the data into information about the solar interior. The investigators for this grant will apply to solar data the techniques already highly developed to interpret seismological data of the Earth.
