Some Observatonal Subjects Which Could Be Selcted in SMY of Cycle 21

Based on the parameters and characteristics of the present observational eguip-ments belonging to the Solar Physics Division of Yunnan Observatory, some interesting subjects which could be for reference and chosen during SMY are proposed in this paper.The problems of the dynamical spectral observations of the phenomena of solar activities are emphatically pointed out, because they have become the most prominent titles in the domain of solar optics at present.
