上下两层的的英文

bilevel

例句与用法

By extending the pyroelectric theory of a ferroelectric bilayer , we have presented the effective pyroelectric coefficient of a ferroelectric sandwich structure by use of the electrostatic theory . when the pyroelectric coefficient of the interface has a large deviation from that of the two - sided slabs and the dielectric constant of the interface is low , the effective pyroelectric coefficient of the sandwich structure may be one or two order higher than the largest pyroelectric coefficient of the components
我们应用静多层结构铁电系统的物理性质研究摘要电场理论，推广了铁电双层膜的热电理论，给出了铁电三明治结构的有效热电系数，发现在界面层的热电系数与上下两层的热电系数差异较大，且界面层的介电常数较小的情况下，三明治这种复合结构材料的有效热电系数比单一组份材料的热电系数可以提高一到两个数量级。
