和是能源科学和工程热力学中引出的新概念。利用和可以更科学地揭示能量的本质涵义，更具体地描述能量转换规律；分析法比能量平衡分析法更准确地反映了能量的利用情况，更明确地指出了合理用能的方向和条件；“节与“节能”相比，提法更严谨，含义更深刻，应用起来更科学，更具有可操作性。

Saving Energy a New Conception of Using Energy in Reaxon──To Save Exergy

'Exergy'(useful energy) and 'anergy'(useless energy) are new conceptions created out of exergy science and engineering theromdynamics. To make full use of esergy and anergy will reveal the essen tial nature of exergy more scientifically,and illustrate the law of Conservation of Exergy in details. Exergy Analysis, in comparison with Energy Balance Analysis,will show us more accurately the consumption of en ergy,and point out the direction and conditions to make use of energy reasonable more clearly. Compared with 'saving energy', 'saving exergy'is a scientifical term. Its meaning is more reasonable. To use it will be more correct and operable.
