首次发现在甲苯、杜苯等芳烃共敏化下，可以使原来不能进行的、热力学不利的四环烷→降冰片二烯异构化得以进行，并根据CIDNP结果提出这是由于生成了敏化剂/底物/芳烃三元基激络合物使反应的势能面改变造成的并促进单线态的系间窜跃。

In the paper, a series of metallorganic compounds have been studied by the quantum-chemical calculation with proper basis sets, including:1. a series of carbonyl complexes.2. dibenzene chromium and its derivatives3. ferrocene and its derivatives4. a series of metallic complexes with acetylacetoneWe optimized the geometric configurations of a series carbonyl complexes including Ni4 Fe5, Cr6 with density functional theory B3LYP method at the different levels and confirmed the stable geometry by vibrational analyses. Then we calculated the nuclear magnetic resonance spectra with GIAO method provided by GAUSSION98 program at the different levels.

本文用量子化学计算程序，用密度泛函B3LYP方法，在恰当基组水平上，用GAUSSIAN98程序提供的GIAO方法研究了系列金属有机化合物的核磁共振谱：一、羰基配合物系列：二、二苯铬及其衍生物系列：三、二茂铁及其衍生物系列：四、乙酰丙酮的配合物系列：我们用密度泛函B3LYP方法，在不同基组水平上对第一过渡系羰基化合物的系列配合物进行了结构优化，通过振动分析确定其稳定构型，然后再用密度泛函B3LYP方法在不同基组水平上，用GAUSSIAN98程序提供的GIAO方法计算其核磁共振谱。

With Zn〓 used as an internal standard, the contents of Ni, Co, Cu in real mineral samples were determined successfully in the imidazole or phenylamine systems.

以Zn〓作内标，采用内标标准曲线法分别在咪唑和苯甲胺缓冲液体系中对镍矿样中Ni，Co，Cu的含量进行了测定。

The gas phase oxidation of o-xylene to phthalic anhydride at low oxygen concentration was studied.

近年来，国外对邻二甲苯氧化制苯醉的高负荷催化剂进行了大量的研究工作，其中V-Ti系催化剂得到广泛的应用

At least half of patients with X-ALD are adults with somewhat milder manifestations, and women who are carriers may become symptomatic. X-ALD is often misdiagnosed as attention-deficit/hyperactivity disorder in boys and as multiple sclerosis in men and women, and is not an uncommon cause of Addison disease;(2) the incidence of X-ALD, estimated to be 1:17 000 in all ethnic groups, approximates that of phenylketonuria;(3) noninvasive and presymptomatic diagnosis and prenatal diagnosis are available; family screening and genetic counseling are key to disease prevention; and (4) new therapies, applied early, show promise.

至少1半的X-ALD为成年病人，表现较轻，而作为携带者的女性也可发病。X-ALD在男孩常误诊为注意缺陷/多动综合征，男女可误诊为多发性硬化，并且也是Addison病的病因；(2)据估计X-ALD发病率为1：17 000，类似于苯丙酮尿症；(3)可进行无创性、症状前诊断和产前诊断；家系筛查和遗传咨询是疾病预防的关键；(4)早期采用新的治疗方法非常具有前景。

Conelusion:Missense mutation of Tyr486Asp in Exon 5 of UGT1A1 gene is the pathogenic factor of the CN Ⅱ case in the family and recessively inherited.

Tyr486Asp突变是本例CN—Ⅱ家系的致病性基因，该突变不影响UGT1A1基因启动子区苯巴比妥酸的应答元件，其遗传规律符合常染色体隐性遗传。

Missense mutation of Tyr486Asp in Exon 5 of UGT1A1 gene is the pathogenic factor of the CNⅡ case in the family and recessively inherited. The mutation has no influence on the response elements of phenibarbital in the promoter region.

Tyr486Asp突变是本例CN-Ⅱ家系的致病性基因，该突变不影响UGT1A1基因启动子区苯巴比妥酸的应答元件，其遗传规律符合常染色体隐性遗传。

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。
