The diblock copolymer of styrene and chloromethyl-4-vinyl-benzene was obtained by means of reverse addition fragmentation chain transfer reaction living free radical polymerization. The chloromethyl groups in PS-bPCVB were transformed into azidomethyl groups, and then into 1,2,3-triazol groups via click chemistry. The diblobk copolymer containing 1,2,3-triazol groups was thus obtained. The results from NMR spectra suggested a complete transformation from chloromethyl groups to triazol groups.

To improve the effect of CDCA on dissolving cholesterol gallstone, the water-soluble copolymers as polycarboxylic acid of comb-like copolymers and C_(60)-PCC were synthesized, which being used for modification of CDCA and strengthening effects of CDCA on dissolving the cholesterol gallstones by their entropy-repelled properties of comb-shaped side chains in buffers of phosphate and in model bile.The design theory of polymer was mainly employed to synthesis the conjugate of PCC-CDCA and C_(60)-PCC-CDCA by C_(60), polyoxyalkylene allylalkyldiether and maleic anhydride, which were copolymerized with AIBN as initiator, and then PCC or C_(60)-PCC were reacted with CDCA. The structures of the copolymers and the conjugates of PCC-CDCA and C_(60)-PCC-CDCA were confirmed with IR, TLC and TEM. The dissolving effects and the dissolution kinetics mechanism of cholesterol gallstone was inverstigated in PBS and in model bile of different cholesterol saturated index at pH7.4, including PCC-CDCA or C_(60)-PCC-CDCA.

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。
