本文通过对用不同模具所浇铸出的铝合金块状标样均匀性的研究，分析和讨论了模具几何参数对标样均匀性的影响。同时，对其它影响因素也进行了一些探讨。
In this paper, the homogeneity of the aluminum alloy lumps cast by different molds is studied, and the influence of the mold geometrical parameters on the uniformity of the standard samples is analyzed and discussed. At the same time, some other factors have also been discussed.
