| 摘 要： | 本文对有用能——火用的概念和起源做了简单介绍，并分别概述了化学火用和累积火用的基本理论以及在应用上的意义。指出了当前火用分析存在的问题，进而提出了“投入产出火用函数”，并以此对可再生能源、不可再生能源以及循环能源的转换利用进行了火用分析，得出了只有不断加大可再生能源在能源结构中的比例和提高转换过程的火用效率，才能减缓地球火用衰减的结论。 |
| 关 键 词： | 化学火用 累积火用 火用分析 |

| Abstract: | The concept and origin of available energy—exergy were briefly introduced, theories about chemical exergy and cumulative exergy consumption and the significance of their application were presented in this paper. Problems existed in exergy analysis were poited out, and then the exergy input-output function was introduced to make exergy analysis on renewable energy, nonrenewable energy, recycling energy conversion and utilization. Conclusion was made that the depletion of global exergy could be relieved if only the proportion of renewable energy in the energy structure was increased and the exergy efficiency of conversion process was improved. |
| Keywords: | chemical exergy cumulative exergy consumption exergy analysis |
