The displacement of each mode is determined by a balance between the energy fed into the riser over lock-in regions and the energy dissipated by the fluid damping over the remainder.

各阶模态的响应位移通过平衡涡激锁定区域内柱体的输入能量与非锁定区内流体阻尼的耗散能量计算得到。

Then, by means of the energy balance relation, a new cohesive stress law of Mode I crack is obtained which is only concerned with the surface energy density within the cohesive zone.

然后，利用能量平衡关系，得到仅与表面能密度相关的I型裂纹内聚力新的本构方程。

While the car is on the move, the electric drive itself contributes to a favourable energy balance through recuperation, by converting kinetic energy into electric current in deceleration mode and during braking and feeding this energy into the battery.
