the largest radio telescope in the United States; called the very large array or the VLA, and the Soviet Union's largest radio telescope, called the RATAN 600, will be used to observe the sun for ten days each year during a three-year period. This will lead to a greater understanding of the radiative output of the sun; it is this output that powers all global changes on the Earth. Our joint research project will enhance the scientific return of both instruments beyond that is expected from using either one alone. Spectra and polarization data taken with the RATAN 600 at eleven wavelengths between 0.9 and 20.0 cm will be combined with VLA observations of high angular resolution at 2, 3.6, 6, and 20 cm to determine radiation mechanisms and coronal magnetic field strengths for the various sources of intense, quiescent solar radiation. *** //

美国最大的射电望远镜；被称为甚大阵列或VLA，苏联最大的射电望远镜，被称为Ratan 600，将在三年内每年用来观测太阳十天。这将使人们更好地理解太阳的辐射输出；正是这种输出推动了地球上所有的全球变化。我们的联合研究项目将提高两种仪器的科学回报，超出单独使用其中一种仪器的预期。Ratan 600在0.9到20.0厘米之间的11个波长的光谱和偏振数据将与2、3.6、6和20厘米的高角度分辨率的VLA观测相结合，以确定各种强烈、静止的太阳辐射源的辐射机制和日冕磁场强度。*//
