The results show that the SSC can cause the topography flattening only in constant viscosity model; for the model with temperature-dependent viscosity, although the SSC enhances the surface heat flux, it has little effects on topography.

• 数据结果显示，在常粘性模型中，小尺度地幔对流可造成海底地形抬升；但对与温度相关的粘性模型，小尺度对流对地形几乎不产生影响。
