因为水分子在微波电场下有强烈及明显的介电效应，其介电值约为80。
Since the water molecule has very strong dielectric effect under the microwave field, its dielectric constant is about 80.
但绝大部份的结构材料在微波电场下却只有轻微的介电效应，其介电值主要在3至6之间。
However, most building material has very small dielectric effect under the field, its dielectric constant is from 3 to 6.
