The curves of C-T and tgδ-T for th.

介电温谱测试表明,随着温度的升高,梯度薄膜出现一个铁电-铁电相变点和两个居里点,同时出现一定的频率弥散现象。

09(Bi_2O_3·3TiO_2)dielectric Ceramics(abbreviated as SrTiO3 based Ceramics)were Prepared by the standard Solid-state reaction method,and their dielectric Spectra,Viz,dielectric temperature spectrum and dielectric frequency spectrum were investigated in detail.

０９（Ｂｉ２Ｏ３·３ＴｉＯ２）介电陶瓷（缩记为ＳｒＴｉＯ３基陶瓷），并详细地研究了此种陶瓷的介电谱，即介电温度谱和介电频率谱。
