常見例句雙語例句In mantle convection models, the mantle viscosity is generally assumed constant or dependent on depth.粘度為常數(shù)或僅隨深度變化是地幔對(duì)流模型中常用的假設(shè)。The ratio of poloidal to toroidal component of mantle convection determined the proportion of seismic energy released in the thrust, normal, or strike-slip earthquakes.地幔對(duì)流的垂直運(yùn)動(dòng)與水平運(yùn)動(dòng)分量的比率，決定了逆沖、引張與走滑型強(qiáng)震的能量釋放份額。A constant viscosity mantle convection model is developed into a variable viscosity model assumed a latitude-dependent viscosity with small fluctuations on the basis of a constant background value.建立了一維粘度擾動(dòng)下的變粘度模型。 通過假定粘度為常粘度背景下存在僅隨緯度變化的小橫向擾動(dòng)，將常粘度模型發(fā)展為變粘度地幔對(duì)流模型。 返回 mantle convection
