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.

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.

因此我们所得到的适用于四方相的理论公式就会发生一定的偏差。

The rhombohedral pattern R of alite stabilized by certain impure ions is more hydrated.

阿利特或硅酸三钙，(C3S)固溶体是水泥熟料中最重要的矿物，某些杂质离子可以稳定其多晶型中的三方R型，具有较高的水化活性。

Results of Mn doping implied that samples located at rhombohedral-tetragonal morphotropic phase boundary. Small MnCO3 doping resulted in indistinct transition from rhombohedral to tetragonal.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
