The results show that constitutional phases in the 〓 alloy is the same as that in the 〓 alloy, but phase composition and transformation temperatures of two alloys are quite different. The Ms temperature of the 〓 alloy is lower than-180℃. In order to enable the alloy to be used for making pipe couplings, it is necessary to control Al addition and to increase Ti addition in the alloy. In the 〓 alloy, there exist three constitutional phases: TiNi matrix phase with B19′structure,β-Ta phase and NiTa〓 phase. Transformation temperatures, M〓, Ms, As and A〓, of the alloy are 55℃, 66℃, 94℃ and 109℃, respectively.

结果表明，〓合金显微组织的相组成物与〓合金一样，但相成分明显不同，相变温度相差较大，其Ms温度低于-180℃，要想使该系合金用于制作记忆合金管接头，必须控制铝的添加量并提高合金中的钛含量使合金的Ms温度控制在-80℃～-100℃之间；〓合金是由具有B19'结构的TiNi基体相、β—Ta固溶体和NiTa〓化合物三相组成的，其相变温度M〓、Ms、As和A〓分别为：55℃、66℃、94℃和109℃。

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。
