To compound BN and SiO_2 candecrease its T_F, increase its T_G, improve its high temperature dielectriccharacteristics, and therefore is an effective approach to reduce the reentrysignal attenuation of BN antenna window.

• BN/SiO_2复合,可降低其烧蚀表面温度,增大其沿透射方向的温度梯度,从而改善其高温介电性能。 BN与SiO_2复合是减小氮化硼天线窗再入信号衰减的行之有效的方法。
