Besides three sable phases Ni〓Ti, NiTi and NiTi〓, a precipitate appearing needle shape in B〓-TiNi matrix is observed, which is identified as Ti〓Ni〓 phase with rhombohedra structure.

在对两种不同烧结条件样品的显微组织观察中发现1100℃烧结样品的相中有析出相产生，可确定为具有菱面体结构的亚稳相。

Moreover, there exists a morphotropic phase boundary for the composition at x= 0.33 , and the rhombohedra phase and tetragonal phase coexists for the composi tion near MPB, but the pure rhombohedra phase and tetragonal phase separately exists for the composition away from MPB.

陶瓷样品X-射线衍射相组成和相结构分析表明：所有陶瓷样品均为纯钙钛矿相，无任何其他杂相出现；且组成在x=0.33处存在一准同型相界，在该相界附近三方相和四方相共存，而远离该相界则分别为纯三方相和四方相。

Riffle division method: a riffle is a kind of non-mechanical sample divider, which is usually fed manually. The sample is divided into 2 equal parts by riffle, with one retained and one rejected.

二分器缩分法：二分器系非机械式样品缩分器，通常用手工给料，样品通过二分器被分成二等份，一份保留，另一份弃去。

Since a large particle size can easily cause division deviation, material over 10mm is not suitable for coning and quartering method. In this instance a riffle divider should be used.

由于大颗粒样品堆成圆锥时容易产生偏析，造成缩分偏差，样品粒度大于10mm不宜使用圆锥四分法，最好使用二分器。
