摘要
根据模糊集理论，应用多层次的定量化和语言化相结合的模糊综合评判数学模型，全面考虑了与水工建筑物过流表面设计施工、壁面材料和运行情况等方面的因素，并按照各因素对空蚀初生的影响程度，将其划分为不同的层次进行逐层综合评判。这样，不仅能计及可以定量的影响因子，还可以充分利用语言或文字描述的变量，从而得到一个能被工程接受的空蚀初生判别标准。
Based on the mathematic model of synthetic judgement with multistage quantization and word picture in the Fuzzy theory, the state of incipient cavitation are estimated, which considers varieties of effective factors that the solid wall surface irregularities and materials of spillway as well as the operation of water conservancy project. As such, not noly thinking over the quantization factors but also making full use of word or language variables, the evaluation method of incipient cavitation has been given in this paper.
