Super-fine K-doped Li2ZrO3 powders were synthesized via the citric acid-ethylene glycol complexing, with the nitrates of lithium, zirconyl and potassium as the materials. Then, the precursor of K-doped Li2ZrO3 and the K-doped Li2ZrO3 powders were characterized by means of TG-DSC, XRD and SEM. Moreover, the thermal decomposition of the gel and the formation of the tetragonal crystalline form were analyzed.

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。
