准确地评判物质平衡变化趋势则需将物质平衡与冰体动力学结合起来，并建立冰-海-气耦合模型。
It is necessary to combine the mass balance with the ice sheet dynamics and to develop the couple model of ice-ocean-atmosphere for accurate estimate of the mass balance state and its variability.
这写着在平衡状态一种物质，的浓度变化等于零，我们一会儿也会把它用作一种近似，当我们学习更复杂的机理的时候。
Writing at equilibrium that the change in the concentration of one of the species is equal to zero, we're going to use that as an approximation also later, when we get to more complicated mechanisms.
它还和大脑的生理变化相关和一种给大脑和神经传递信号的化学物质的不平衡有关。
It is related to physical changes in the brain, and connected to an imbalance of a type of chemical that carries signals in your brain and nerves.
