evaporative cooling, exergy analysis, indirect heat exchange,imbalanced flow,quasi-counterflow heat exchanger,numerical simulation,effectiveness.

蒸发冷却,(火用)分析,间接热交换,不平衡流,准逆流扳式换热器,数值模拟,换热器效能。

It mainly includes: ①Based on the analyse of chemical exergy and physical exergy, an improved method of exergy is put forward in which the exergy change of mixing is considered.

主要包括:①改进了一般有效能分析方法,在化学有效能和物理有效能的基础上,引入了混合物质状态变化(特别是压力有较大变化)时的有效能变化值。

And exergy shows maximum utilities and organization, and fitted to be used to measure the productivity. APES are specially used here to distinguish from the concept of Agroecosytem Productivity derived from Ecosystem Productivity.

能值是能量的记忆,因为不能反映投入的品质、副产品开发、循环经济等农业生产的许多重要特征,不适合于测算系统生产力,而适于测算农业生态系统的总成本;最大潜能表示最大有用性和系统组织程度,适用于测算系统生产力。
