立方形堆积和孔隙度为47.6%，菱形堆积的孔隙度为25.96%。

The adding of La and Sr will lead to an increase in the content of the rhombohedral phase and in the degree of the phase diffuseness and the frequency dispersion.

研究了组成、掺杂和工艺等因素对压电和介电性能的影响，首次采用烧结后的退火工艺得到了一系列具有良好压电和介电性能的弛豫铁电陶瓷体系。

Chapter 4: Influence of the angle distortion induced from rhombohedral La_(0.7)Sr_(0.3)MnO_3 grown on the cubic substrates on the structure and transport properties of CMR thin films is carefully studied.

第四章研究菱形结构的La_(0.7)Sr_(0.3)MnO_3生长在立方衬底上引起的角度畸变对薄膜的微结构和电磁性质的影响。

This angle distortion results from the rhombohedral symmetry of LSMO, when it is matched onto a cubic substrate. As the distortion angle is partially recovered in coherently LSMO films, the transition temperature T_P of the films almost approaches to that value of the LSMO bulk.

因此，菱形的LSMO匹配生长在立方单晶衬底上，除了受晶格参数失配引起的应变外，还存在另一种应变来自于LSMO匹配生长在立方衬底上引起的。

It may be caused by the fact that the researches were mainly focused on the compositions in the rhombohedral and morphotropic phase boundary.

在此组分范围内，由于铁电微畴的影响，很难得到光学级的PMN-PT单晶。

The results showed that the phase structure transferred from rhombohedral to tetragonal phase with increasing BKT content.

结果表明：随着BKT含量的增加，体系的相结构由三方相向四方相过渡。

The PZT system lies in the border between the tetragonal phase and the rhombohedral phase region.
