摘　　要：采用微扰法,研究了不同质量分数的ZnO以及不同的热处理制度对SiO2-Al2O3-MgO-La2O3微晶玻璃系统微波介电性能的影响。结果表明,ZnO能有效地改善SiO2-Al2O3-MgO-La2O3系微晶玻璃的微波介电性能。当ZnO质量分数为8%,在850℃下保温处理72 h,得到的样品最佳参数为:εr=14.053,Q=1 338.821,τf=85×10-6/℃。The effects of different mass fractions of ZnO and different heat-treatment procedures on the microwave dielectric properties of SiO2-Al2O3-MgO-La2O3 glass ceramic system were investigated by perturbation method. The results show that ZnO improved microwave dielectric properties of LMAS glass-ceramic effectively, the best sample parameters are as follows： εr=14.053,Q=1338.821,τf=85×10^-6/℃, when treated under 850℃ for 72 hours with ZnO mass fraction of 8 %.
