G产品+ G回收+ G流失式中：G投入投入系统的物料总量；G产品系统产出的产品和副产品总量；G流失系统中流失的物料总量；G回收系统中回收的物料总量。其中产品量应包括产品和副产品：流失量包括除产品、副产品及回收量以外各种形式的损失量，污染物排放量即包括在其中。系统中物料衡算一般表达式为：系统中的积累=输入-输出+生成-消耗式中，生成或消耗项是由于化学反应而生成或消耗的量；积累量可以是正值，也可以是负值，当系统中积累量不为零时称为非稳定状态过程；积累量为零时， 称为稳定状态过程。稳定状态过程时，可以简化为：输入=输出-生成+消耗对无化学反应的稳定过程，又可表示为：输入=输出物料衡算包括总质量衡算、组分衡算和元素衡算。各种衡算方法的适用情况如表1-1所示：表1.1
