三、合成了系列的含有不同氮杂烷氧链的查尔酮衍生物。

We also studied the enantioselective conjugate addition of chalcone in the presents of chiral Ni2 aminoalcohol complexes.

我们还研究了手性氨基醇配体/镍盐催化的a，β-不饱和酮的不对称迈克尔加成反应，以及酰腙的不对称烯丙基化反应。

Five expressed genes contributed to the flowering process and embryonic development such as prolamine, gene for allergenic protein, chalcone synthase, putative peptide methionine sulfoxide reductase and acyl carrier protein Ⅱ gene were chosen to hybridize with a 1510-RNA-blot (time-point phenotypes) array. The 1510 RNA blots were prepared into an RNA array for the purpose of conferring and validating global transcriptional profiles on booting, flowering and filling quantitatively and qualitatively at a statistic level. The results verified: Prolamine and allergenic protein were high-expressed in filling grains after being regulated by development, Chalcone synthase and methionine sulfoxide reductase were high-expressed in the leavies induced by light, in the root stressed for nitrogen deficiency.

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。
