Thermal imidization of the polyamic acid derived from BPADA and BAPS was investigated mainly by GPC and FTIR equipped with an in-situ hot cell.

利用GPC、原位FTIR测定了长链聚酰胺酸PAA由双酚A二酐与 4 ，4′-二(4-胺基苯氧基二苯酚制备的热环化过程。

The polymerization mechanisms of DTC, TMC and CL initiated by Ln 〓 were fully studied for the first time, and proved to be a"coordination insertion anionic mechanism". Monomer coordinated to rare earth metal on the carbonyl group, and opened ring via acyl-oxygen bond cleavage, forming a growing chain.

本文首次研究了Ln〓引发DTC、TMC和CL聚合的机理，证实都符合&配位插入阴离子机理&：单体首先以环外羰基和引发剂中稀土原子配位，并发生羰基加成，随之通过酰氧键断裂开环而插入到Ln-O键中实现链引发，然后各单体重复上述稀土原子参与的配位、加成、开环、插入聚合步骤，活性链在Ln-O端增长。

X 6.36(3)? is formed.Liquid-liquid extraction experiments, between twelve heterocyclic thioalkoxycalix[4]arene on the lower rim, fifteen heterocyclic thioacetamidecalix[4]arene on the upper rim and Na~+、K~+、Cs~+、Mg~(2+)、Cu~(2+)、Co~(2+)、Cd~(2+)、Ni~(2+)、Pb~(2+)、Hg~(2+) and Ag~+ picrates, have been carried out and their results are compared.

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.
