Hindered amine light stabilizer of Cyasorb UV-3346 was synthesized in total yield of 60% by three steps from cyanuric chloride,morpholine and N,N′-bis-(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexanediamine as starting materials.

以三聚氯氰、吗啉和N，N′-二(2，2，6，6-四甲基-4-哌啶基)-1，6-己二胺为原料用3步法合成得到受阻胺类光稳定剂Cyasorb UV-3346，总收率为60%。

The morphology of scaffolds shows a regular morphology at high molecular weight. Furthermore, pore size was increased with high phase separation temperature, long coarsening time, and high concentration of nonsolvent.

反之在没有非溶剂的存在下(100/0二氧陆环/水)，高分子溶液系统仅会出现固-液相分离，显示聚乳酸与二氧陆环是互溶性佳且稳定的溶液系统。

In this article, different soft templates formed by sodium bis (2-ethylhexyl) sulf-osuccinate, nonyl phenol polyethyleneoxy ether (Oπ-10) and cetyltrimethyla- mmonium bromide were used to fabricate CaCO3, BaCO3 and CeO2/CuO nanoparticles with different morphology.

本文分别利用丁二酸二(2-乙基己基)酯磺酸钠、壬基-酚基-聚乙氧基醚（Op-10）和十六烷基三甲基溴化胺形成的不同软模板合成了具有不同形貌的CaCO3， BaCO3和CeO2/CuO纳米粒子。

Methods: P-toluenesulfonic acid diethoxyphosphorylmethyl ester (4) was prepared from diethyl phosphate and paraformaldehyde by condensation and esterification.

以亚磷酸二乙酯和多聚甲醛经缩合、酯化得到对甲苯磺酸羟甲基磷酸二乙基酯(4)。

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.

交际能力和语法的关系应该是目标与途径的关系。
