Braun, Douglas 95-28249 Dr. Braun's project is a combination of both observation and theory to determine and interpret the characteristics of acoustic scattering and absorption by solar active regions. The measurements include a database consisting of recent high quality solar observations carried out at the geographic South Pole in 1990 and 1994 and on Kitt Peak. To be determined are the complete acoustic scattering properties for a wide variety of active regions with different surface morphology and at different stages of their evolution. The theoretical effort will be to model acoustic scattering by sunspot flux tubes, improving on the PI's present model with a more realistic treatment of the effects of the magnetic fields in the sunspot scatterer. Finally, using both theoretical modeling and observations, the scattering signatures produced by completely submerged inhomogeneities will be explored. ***

布劳恩，道格拉斯95-28249布劳恩博士的项目是观测和理论的结合，以确定和解释太阳活动区的声波散射和吸收特性。这些测量包括一个数据库，其中包括1990年和1994年在地理南极和基特峰进行的最新高质量太阳观测。待确定的是具有不同表面形态的各种活动区以及其演化的不同阶段的完整声散射特性。理论上的工作将是模拟太阳黑子通量管的声波散射，改进PI目前的模型，更真实地处理太阳黑子散射体中磁场的影响。最后，利用理论模拟和观测，将探索完全淹没的不均匀所产生的散射特征。***
