通过混合三聚反应，也合成了另一类含两个二茂铁化合物， N，N'-二-2-羟基-5-特丁基苯甲二胺。

With regard to bioactive components, rutin, quercetin and γ-aminobutyic acid were detected in husked buckwheat bread and unhusked buckwheat bread whereas those components were not found in white bread.

在机能性成分方面，带壳荞麦土司及去壳荞麦土司皆测出芸香苷、槲皮素及γ-胺基丁酸之成分，而白土司并不含有此三种成分。

They were two new compounds, [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu),7],[2-N-(1-methoxycarbonylethyl)guanosine, 10], and eight known compounds,(p-hydroxybenzoic acid, 1),(methyl succinate, 2),(russulaceramide, 3),(phenylalanine, 4),(guanine, 5),(β-carboline, 6),(uridine, 8), and (adenosine, 9). All the compounds were isolated from Amanita exitialis for the first time.

分别为：对羟基苯甲酸(p-hydroxybenzoic acid，1)、丁二酸二甲酯(methyl succinate，2)、神经酰胺(russulaceramide，3)、苯丙氨酸（phenylalanine，4）、鸟嘌呤核苷(guanine，5)、β-咔啉(β-carboline，6)、环（脯氨酸-缬氨酸-苯丙氨酸-苯丙氨酸-脯氨酸-缬氨酸-苯丙氨酸-丝氨酸-亮氨酸） [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu)，7]、尿嘧啶核苷(uridine，8)、腺嘌呤核苷(adenosine，9)、2-N-(1-甲氧羰基乙基)鸟苷[2-N-(1-Methoxycarbonylethyl)guanosine， 10]。10个化合物均为首次从致命鹅膏中分离得到，其中化合物7和10为新化合物。

EMB-resistance in 18 isolates was caused by the mutation at coden 306 in embB gene with positive rate of 62.1%. The PCR result was negative in 20 specimen from pulmonary diseases without active TB and 5 negative control strains of no MTB. The data in this study showed high specificity of 100%. Only one specimen in 7 specimen with negative result in acid-fast stain and cultivation was shown alteration in coden 306 in embB gene.

结果：130例活动性肺结核患者痰标本抗酸染色阳性38例，阳性率为29.2%(38/130)；罗氏培养阳性为79例，阳性率为60.8%(79/130)。79例培养阳性痰标本中耐乙胺丁醇29例，其中有18例在embB基因met306ATG突变，基因突变率为62.1%。20例非结核肺部疾病患者痰标本和5株非结核分枝杆菌菌株经套式PCR扩增全部为阴性，特异性为100%。7例涂阴培阴PCR扩增阳性的序列中有1例在embB基因306位密码了发生突变。

Bezaldehyde was used as protective agent in first method.S-Epichloeohydrin was aminated and acidulated to give(2S)-1-Amino-3-chloro-propanol Salts.The acetylation of (2S)-1-Amino-3-chloro-propanol by acetic anhydride produced the intermediate-N-[2--3-chloropropyl]acetamide.And then at 20℃,in the presence of lithium tert-butoxide,benzyl 3-fluoro-4-morpholinophenyl carbamate react with-N-[2--3-chloropropyl]acetamide to give linezolid in total yield of 43.6%.

路线一采用苯甲醛作保护剂，使S-环氧氯丙烷氨解、酸化生成S-1-氨基-3-氯-2-丙醇盐酸盐，然后经乙酰化反应后，生成中间体-N-[2-乙酰氧基-3-氯丙基]乙酰胺，再用N-(3-氟-4-吗啉苯基)氨基甲酸苄酯和中间体在催化剂叔丁醇锂存在下25℃反应生成利奈唑酮，总产率达到43.6%。

An ammonium nitrogen in paddy field showed the same tendency of reduction as ammonifying bacteria.

随着丁草胺+尿素使用剂量的提高，土壤氨化细菌含量显著下降，土壤铵态氮含量也呈现相同的下降趋势。

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.
