But for ethanol made from trees, grasses and other types of biomass which contain a lot of cellulose, the energybalance can be as high as 16, at least in theory.
从树、草和其它含有大量纤维素的生物资源中制出的乙醇,其“能量平衡”值起码在理论上能高达16。

A mathematical model of heat loss of high temperature smoke vented from rotary anode furnace in copper refining based on warm-up burning air was established based on principle of energybalance.
This paper analyses the energybalance during the electric furnace steelmaking of An-long. We find the fundamental causes and affecting factors of high electricity consumption.
