The model includes reaction rate equations, gas-liquid equilibrium and gas-liquid mass transfer equations, so that the simulation gives close results to the commercial practice.

数学模型中包括了反应动力学方程、气液平衡和气液传质方程，使模拟结果接近于工厂实践。

Also if you want to calculate chemical equilibria in the liquid and gas phase, of course, now you've seen chemical equilibrium, so the amount of reaction depends on the composition.

如果你想计算液相，和气相的化学平衡，当然，你们知道化学平衡，反应的量决定于组分的比例。

But again, if you know all the energies of the possible states, in the solid, in the liquid and the gas, statistical mechanics shows us that we can calculate the equilibrium between those.

但是，如果我们知道，物质在固相，液相和气相中所有可能态的能量，统计力学告诉我们，我们可以计算这些相的平衡问题。
