中文摘要：

建立了由海底热点隆起横截面地形估算地幔柱体积流量的简单模型,并在去除了海洋岩石圈冷却下沉、海山以及沉积层影响的情况下,运用该模型对Hawaii热点隆起的27个区域的横截面地形曲线进行了拟合分析,估算了Hawaii地幔柱体积流量在过去35 Ma中的变化,并观测到距今3～4 Ma和距今17～19 Ma的两个峰值。

英文摘要：

A flexure model is formulated to estimate mantle plume volume flux through hotspot swell topography. By using the model curve to best fit the actual seafloor topography on 27 cross-sections of Hawaiian swell, the temporal variation in volume flux of Hawaiian plume during the past 35 Ma is estimated, and two volume flux peaks at 3-4 Ma and 17-19 Ma before present are observed.
