摘　　要：用极顶设计法确立最优化７组分玻璃固化体试验方案。对方案中１０２个试验配方进行高温粘度和电导电阻率工艺性能测试，并对其中经过调整的８６个配方建立高精度高阶重心多项式工艺性能预测模型。用伪组分法定量计算玻璃固化体各组分Ｓｉ、Ｂ、Ｎａ、Ｃａ、Ａｌ、Ｕ等氧化物和“废物混合物”对配方工艺性能的影响。An experimental D-optimum design of 7-component nuclear waste vitrification is established by the extreme venice design method. The high-temperature viscosity and the electric resistance of 102 compositions in this design are tested, where the experimental values of modified 86-composition design are used to establish the highly precise cubic Scheffe models for predicting the performances of the viscosity and the electric resistance of waste forms. The component effect of SiO2,B2O3, Na2O, CaO, Al2O3, U3O8 and the waste mixture WmOx on the two properties of waste forms are also calculated by the pseudocomponent exchange method.
