stage circulation

This paper introduced a energy saving method which makes a drying proces of waste gas stride over step circulation so that wate gas remaining heat on three steps fluid-bed lrying equipment can be in full use.

为了使三级流化床干燥装置的废气余热能充分利用 ,本文提出了一种节能方法 ,采用废气跨级循环的干燥流径。

Model of mutual-circular material flow of industrial eco-chain was developed, which will provide some guidance in the study of industrial ecosystem.

以工业代谢为理论基础,运用系统分析与建模的方法对工业生态系统中的企业及其所构建的工业生态链进行理论分析与描述,揭示了工业生态系统中物质代谢及循环流动机理,并提出了简化的工业生态链的梯级循环物质流模式及其数学表达模型,对我国开展工业生态研究具有一定的参考价值和指导意义。
