摘要：

Material motions on the solar surface have been deduced from the wavelength shift of Fe I lambda-6302.5 angstrom, measured over the umbra and inner penumbra of a spot for which the magnetic field configuration has already been established with some confidence. The two vector fields are considered together in detail and the results support the 'convective roll' sunspot model (Spruit, Galloway). For the magnetic field regions, both material flow along the field lines and field line motions are derived. A small upward motion only is deduced for the field free regions.
