| 摘 要： | 研究了ＳｉＯ２－Ｓｉ３Ｎ４天线窗材料的热学性能和抗热震性能。结果表明，复合材料的热膨胀系数、导温系数、导热系数随Ｓｉ３Ｎ４含量的增加而增大，对于同一Ｓｉ３Ｎ４含量的复合材料，三者均随温度的升高而增大，复合材料保持了ＳｉＯ２基体材料的良好抗热震性。

| Abstract: | Thermology properties and thermal shock resistance of the SiO2-Si3N4 composites were investigated in this paper. It is found that thermal expansion coefficient, thermal diffusivity and thermal conductivity of the composites increase when the Si3N4 content increases; in the same Si3N4 content, they all increase when temperature increase; the composites retain the excellent thermal shock resistance of the SiO2 matrix material. |
