标题： Correlation Analysis of Mode Frequencies with Activity Proxies at Different Phases of the Solar Cycle

摘要： 我们分析了GONG和MDI/SOHO在完整太阳周期中测量的中间度p-和f-模本征频率，以研究它们与太阳活动的相关性。我们证明频率确实与活动呈线性变化，然而相关程度在周期的不同阶段有所不同。在上升和下降阶段，模频率与活动代理变量有很强的相关性，而在低活动和高活动期间，频率与所有考虑的活动代理变量的相关性显著降低。 显示英文摘要

摘要： We analyze intermediate degree p- and f-mode eigenfrequencies measured by GONG and MDI/SOHO for a complete solar cycle to study their correlation with solar activity. We demonstrate that the frequencies do vary linearly with the activity, however the degree of correlation differs from phase to phase of the cycle. During the rising and the declining phases, the mode frequencies are strongly correlated with the activity proxies whereas during the low- and high-activity periods, the frequencies have significantly lower correlation with all the activity proxies considered here.
