The absorption of root system was the main sources of nitrogen in the plant.The effects of matrix ventilation on the abaorption,transportion and metabolism of nitrogen in the root system of cucmber were discussed deeply.The results showed that contents of ammonium,nitrate,free amino acids and soluble protein in cucumber roots were higher in G1 treatment.Contents of ammonium,nitrate and free amino acids in cucumber roots were the trend of the dropping after the first rising in F1 treatment,but contents of soluble protein was lower11.03%than that of the control.

根系吸收是植物体内氮素的主要来源，本研究深入探讨了基质通气状况对黄瓜根系氮素吸收、运输和氮代谢的影响，结果表明G1通气处理根系的铵盐、硝酸盐、游离氨基酸和可溶性蛋白含量均较高；非通气处理(F1处理)根系内铵盐、硝酸盐和游离氨基酸含量呈先升高后降低的趋势，而可溶性蛋白含量始终较低，比对照降低11.03%。G1处理根系硝酸还原酶、亚硝酸还原酶、谷草转氨酶、谷丙转氨酶、谷氨酰胺合成酶活性均较高；而F1处理的酶活性在处理末期显著降低，其中谷氨酰胺合成酶活性比对照降低33.33%。

Using peptide hydrolysis combined with amino acid analysis, sugar alcohol acetylation combining with GC/MS, fattic acid methyl esterization combining with GC/MS and other technical means it was identify carbohydrate in the bioemulsifier mainly was D-mannose, and main amino acids were glutamic acid, aspartic acid, alanine, and main fattic acids that composed lipid was hexadecanoic acid, octadecenoic acid, and octadecanoic acid.

利用肽水解结合氨基酸分析、糖醇乙酰化结合GC-MS、脂肪酸甲脂化结合GC-MS等技术手段鉴定乳化剂中糖主要为D-甘露糖；主要氨基酸为谷氨酸、天冬氨酸、丙氨酸；构成脂的主要脂肪酸为十六烷酸、十八烯酸和十八烷酸。

Then, N-for-aspartame was obtained from the reaction of 3-formyl-4-carboxymethyl-1,3-oxazolidine-5-one and L-phenylalanine methylester hydrochloric acid under sodium acetate anhydrous in ethyl acetate, and the target product was prepared after removing formyl in the mixture system of hydrochloric acid, methanol and water, the yield of aspartame reaches 89.2%.

最后，用3-甲酰-4-羰基口恶唑烷-5-酮乙酸与L-苯丙氨酸甲酯盐酸盐在溶剂中进行接肽反应，然后在甲醇/盐酸混合体系中进行脱甲酰保护基，从而得到最终目标产物，产率为89.2%。

Especially, in the second exon two base substitutions had been found at positions +368 and +456. At position +368, the first result was in substitution of glutamine for arginine. While the second was homonymy substitution at position +456.

在第2外显子有2处碱基取代，分别是+368处的G→A，导致精氨酸→谷氨酰胺，及+456处的T→C，为同义取代，仍为丙氨酸；第5外显子+1572处的A→G，导致组氨酸→精氨酸。

The patients were observed in serum total bilirubin, alanine amino-transferase, alkaline phosphatase, r-glutamyltrans- peptidase peptidase, and prothrombin time the changes.

观察患者血清总胆红素、丙氨酸氨基转移酶、碱性磷酸酶、-谷氨酰转肽酶、及凝血酶原时间的变化情况。

Unlike saccharin, aspartame is unstable and degrades at high temperatures, so it is not useful in cooking.

不像糖精那样，天冬氨酰苯丙氨酸甲酯不稳定。它在高温下会分解。所以，它不能用作烹饪。

Methods: Serum alcohol and ALT、AST、GGT、ALP、CK、LDH、AMY、LIPA measured before and after beer consuming (4ml/kg) in 17volunteers. Meanwhile, the direct inhibitory effects of beer on the serum enzymes were studied by comparing the serum enzyme activities with or without beer.

利用17名健康志愿者，观察口服啤酒(4ml/kg)前后不同时间血液中酒精浓度及丙氨酸氨基转移酶、天冬氨酸氨基转移酶、γ-谷氨酰转肽酶、碱性磷酸酶、肌酸激酶、乳酸脱氢酶、淀粉酶、脂肪酶活性的变化，同时在体外加入血清中与体内浓度相近的啤酒，以观察啤酒对酶活性的直接影响。

The results show that during the development of the oriental tobacco leaves, the activity of acid invertase was decreased; the changes of GS reached its peak in the 20dans in Samsun, but in the 30dans in Basma and Canik ;the activity of PAL was decreased in the 30dans; The content of total nitrogen was decreased with the mature leaves, but nicotine、total carbon and soluble total sugar were increased. Different varieties, carbon and nitrogen metabolism key enzyme activity and the content of metabolites were different.

结果表明，在香料烟叶片发育过程中，酸性转化酶的活性均呈下降趋势；谷氨酰胺合成酶的活性Samsun品种在20d叶龄时最高，而Basma和Canik在30d叶龄时最高；苯丙氨酸解氨酶的活性均表现为30d时最低；随着叶片成熟总氮含量降低，烟碱含量升高，总碳、可溶性总糖随着叶片成熟其含量呈升高趋势；品种不同，碳氮代谢关键酶的活性及代谢产物的含量变化均有很大差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
