The penalty finite element equation for ternary viscous incompressible permanent flow inside the guide shell of an oil transmissionpump is established by using the penalty finite element method.
运用罚有限元方法，对油泵导壳内部三元粘性不可压缩定常流动建立了罚有限元方程。

Inside the transmission, an electric oil pump replaces the torque-converter pump.
同时在变速箱内用一部电子油泵取代了原有的变矩器泵。
