Results showed that expansion coefficient exhibited anomalous behaviours, which at the -80℃ transition phase point temperature that are caused by Jahn Teller of "Ti—Ba—Ti—"on Barium Titanate, at same time, we also discussed that dielectric constant affected by the rate of vacancy on barium titanate.

结果表明在钛酸钡的三个相变温度点（120℃、8℃、－80℃）处，热膨胀系数反常变化，我们认为相变温度为－80℃处的热膨胀反常是因钛酸钡BaTiO3中对称元"Ti—Ba—Ti"的静态畸变造成。同时本文讨论了BaTiO3中空隙对其介电常数的影响。

And the lattice distance expands anomalously with decreasing particle size. Using the model of long-range interaction and its cooperative phenomena altered by particle size, the size-induced cubic-tetragonal phase transition, the anomalous lattice expansion, and the change in chemical bonding characters have been well understood.

采用长程相互作用的晶粒尺寸效应模型，对钛酸钡纳米晶结构相变、晶格间距异常增加、价键性质变化等实验现象给出了合理的统一的解释；并把该模型扩展到解释与钛酸钡晶体具有不同共价性成分的氮化镓等纳米体系的相变以及晶格结构变化现象。

以氢氧化钡、氢氧化锶和钛酸丁酯为原料，采用低温煅烧(300~500℃)法合成了钛酸锶钡纳米粒子。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
