通过分析EPS水泥的内部结构来研究其微波损耗机理，分析了EPS和炭黑填充率、EPS颗粒直径以及试样厚度对材料吸波性能的影响。

The electromagnetic loss mechanism was analyzed and influences of EPS and CB filling ratios, EPS diameter and sample thickness were also analyzed in the paper.

结果表明，封孔涂层表面的孔隙基本被封住，封孔剂及其纳米颗粒可渗入涂层的孔隙中起到填充作用，从而降低涂层的孔隙率。

The results show that the pores of the coating surface are basically sealed, sealing agents and nano-particles can penetrate into the pores of the coating, thereby reduce the porosity of the coating.

建立了由微小颗粒(无定形的或结晶的)和填充空气或水的小孔构成的模型，在此基础上分析了质量密度与折射率的相关性。

The correlation between mass density and refractive index is analysed on the basis of a model comprising compact grains (i. e., amorphous or crystalline) and pores filled with air or water.
