摘　　要：为了对热力体系进行综合研究与评估，运用模糊数学方法，通过研究热力体系的多目标论域与因素指标集之间的相互作用，构造出评估矩阵Ｒ研究对热力体系起重要影响作用的因素指标集内部的相互作用，获得从因素重要程度出发的模糊子集４，并建立适宜的模糊方程Ｂ＝ＡＲ，Ｂ中的各元素反映了在热物理、经济，工程环境特性多因素指标集下的综合评估结果。由于该方程包含工程环境特性的发展因素，因此，它体现了人类社会文明对热力体系客观外界环境约束的印记。A concept of fuzzy analysis of thermodynamic-engineering is established in present paper, which has synthetically considered the physical, economic and engineering conditions for thermodynamic systems. The interaction between the multiobject sets of a thermodynamic system and its restraint factors is formulated into a socalled estimating matrix B; while the effect levels of the restraint factors is expressed in term of a fuzzy set A. Therefore, a fuzzy equation is proposed as: B ~ B A, with B denoting the resulted evaluation of the system under the restraint conditions. The equation is able to reflect the requirements of the human society civilization to the thermodynamic systems since the engineering conditions with their development have been included in it.
