Fuzzy Synthetic Judgement of the Incipient Cavitation

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.
