摘要
针对催化剂研究领域中存在的某些不确定性因素，提出应当使用模糊数学来定量地描述这些客观存在的模糊性。尤其对催化剂配方和制备工艺过程这种复杂体系的研究，由于这些不确定性因素间存在着相互作用和协同作用，使体系高度复杂化，从而在客观上产生了模糊性。但对于传统的研究方法难以起作用的领域，可用豆型模糊关系方程进行处理。根据线性代数和模糊数学的基本定义或规则，可从理论上对这种Ⅱ型模糊关系方程进行推导，获得可行解，并可将其编成计算机程序。本文通过对催化剂制备的二个实例，证实了对于催化剂研究领域等复杂体系，若采用模糊关系方程，仅需少量几次试验，就可获得许多定性及定量的数据，并可为进一步的研究指示方向。
According to cerium indeterminate factors existing in catalyst research, an idea for utilizing the fuzzy mathematics to quantitatively describe these objective reality fuzziness is put forward in this paper. Especially for the research of catalyst formulation and technical process, because of the interaction and synergetic effect of these indeterminate factors,make the system highly complicated, thus the fuzziness is produced objectively. For the field in which traditional research approaches are difficult to tube effect,the model II fuzzy relation equation can be used for treatment of such case. According to the basic definitions or rules of linear algebra and fuzzy mathematics, the model II fuzzy relation equation can be theoretically derived to get feasible solution,and the calculation method can be computerized. Two examples of catalyst preparation in this paper confirm that for the complicate system in catalyst research, many qualitative and quantitative data can be obtained by using the fuzzy relation equation with only a few number of test, in addition, the direction of further research can be indicated.
