Similar lamellar hybrids can be obtained from octa(y-chloroammoniumpropyl) polyhedral oligomeric silsesquioxanes dodecyl benzene sulfonic acid sodium salt C_(18H_(29)NaO_3S, DBSS. Further research shows that different POSS to surfactant ratios result in different arrangement of layers: when there exists excessive POSS, the layer is arranged in a "Alkyl-POSS-POSS-Alkyl" sequence; while on the contrary, the layer is in "Alkyl-POSS" sequence.

实验研究表明，通过调整POSS和表面活性剂的物质的量比例可以改变片层结构，发现当POSS成分大大过量的时候，片层重复单元按照&烷基-POSS-POSS-烷基&顺序排列，对应较大的层间距；当表面活性剂成分大大过量的时候，片层重复单元按照&烷基-POSS&顺序排列，对应较小的层间距。

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。
