Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50%red uction using TEM and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non-cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play.

采用TEM对冷轧多晶铜与多晶铝的形变显微组织演变进行了对比研究。结果发现：多晶铜及多晶铝形变显微组织中均含有三类典型的位错结构类型，其中的两种结构特征在两种材料中是相似的，这两种类型结构存在于非立方取向晶粒，可通过晶粒中位错边界的晶体学取向加以区别，另一类型结构存在于立方取向晶粒；晶粒的晶体学取向决定了其形变显微组织类型，但其它冶金学因素对显微组织也有影响。

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。
