摘 要:The variations of NO\+-\-3 concentration in the Guliya ice core are reconstructed for recent about 1 000 a. Spectrum analysis of NO\+-\-3 indicates significant periodicities in the variations of NO\+-\-3 concentration, which coincide with the periodicities of the solar activity. Therefore, a positive correlation between the variations of NO\+-\-3 concentration and the solar activity is found.The variations of NO3+- conccntration in the Guliya ice core are reconstructed for recent about 1 000 a.
