摘　　要：采用因次分析法,利用相似理论求得金属丝过滤器、泡沫陶瓷过滤器、直孔陶瓷过滤器流动阻力与相关因素之间的数理方程,由此可得到过滤器在浇铸系统中的截面放大公式,为精确设计含过滤器浇注系统提供了必要的依据。The relations of flow resistance of woven metal filter, ceramic foam filter, straight hole ceramic filter with relative factors has been built by analyzing with orthodox regression and minimum differences square and the section enlarging formulae for casting system with filters have been gotten. The results give an importante reference for the design of casting system with filter.
