After heat treatment at 1100C in air, the elements of the substrate and the bond coat diffuse and the diffusion of Ni is an uphill diffusion. The layer of r " phase and the layer of A12O3 or NiAl2O4 were formed at the interface of the substrate and the bond coat and at the interface of the bond/top coat, respectively. The thickness of the r " phase and the oxide layer increases with the increase of the time of the heat treatment.

经1100℃热处理，基体和底层中元素发生了相互扩散，并在界面析出γ'相，γ'的存在使界面的结合为冶金结合；在底层／面层界面由于底层被氧化和Al与ZrO_2氧化还原反应形成Al_2O_3等氧化物，Y'和氧化物的厚度随热处理时间延长而增加。

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.
