A multivariable control system has been developed which manipulates heataddition and inflow so as to control digestion temperature and effluent substrate concentration.
多变量控制系统的操作变量为供热量和进水量，被控变量为消化温度和消化污泥排出浓度。

The storage of sensible heat, on the other hand, allows flexibility as to temperature; in addition, safe substances like water and most rocks have large sensible heat capacities.
另一方面，感热的储存允许温度有一定的灵活性。此外，水和大多数岩石等安全物质具有较大的感热容。
