主要产物

Many by-products were detected in the reaction mixture and considered to be formed deriving from water, solvents and the reactants themselves.

检测中发现了很多副产物，主要来自是体系内的水分、溶剂和反应物本身。

The results showed that the main product was benzaldehyde and a little by-products were styrene oxide and phenylacetaldehyde.

发现该工艺中主要生成苯甲醛，少量副产物是环氧苯乙烷和苯乙醛等。

Benzaldehyde, cyclohexanone, and octanal were the major products from their respective alcohols.

苯甲醛、环己酮和辛醛等是相应醇的主要氧化产物。

The yield of 4-methoxybenzophenone can reach 92%,and the main by-products are 2-methoxybenzophenone and phenol benzoate.

反应的主要副产物为2-甲氧基二苯甲酮和苯甲酸苯酯。

The antibodies were purified and the purity and specificity were identified by SDS-PAGE and Western-blot,respectively.Lung tissues from five pigs with PRRS were tested with the established method,which clearly demonstrated the abundant presence of viral antigens in the cytoplasm of alveolar macrophages,and to less extent in alveolar and bronchiole epithelial cells.

SDS-PAGE和Western-blotting检测结果表明，制得的兔抗PRRSV IgG纯度较高，具有良好的特异性，可用于原位检测病猪肺组织中PRRSV抗原的分布；Envision法的检测结果显示，PRRSV抗原的阳性表达产物主要出现在肺巨噬细胞胞浆内，其次为肺泡上皮细胞和细支气管黏膜上皮细胞；通过对5份经RT-PCR检测确认的PRRS病猪肺组织进行检测，均有较高的阳性细胞表达，平均阳性细胞率为46.5%。

Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.

由氰氮化钙（0.5及1.0%处理者）之抑制曲线在不同的时间出现两个抑制区，而尿素则仅有一个，及氰氮化钙对萎凋病菌菌丝生长及产胞的影响远较尿素为甚，显示氰氮化钙之所以能有效抑制萎凋病的主要因子，或许是来自其中间产物，包括尿素及氟酸的杀菌作用。

In the chapter four,the main study was focused on [60,70]fullerene reaction with 4,4,5,5-tetramethylidazoline- 2- thione and DL- valine and other α-aminoacids. The results ofcharacterization showed that it was a carbene reaction. The possible mechanism wasput forward based on the results of characterization.

第四章，主要研究了[60，70]富勒烯，4，4，5，5-四甲基咪唑啉-2-硫酮与DL-缬氨酸和其它氨基酸的反应，通过对反应产物的详细的表征，发现该类反应是一个产生卡宾的新反应。

The discussion of the degradation mechanism: Chitosan is not hydrolyze in neutral soak in vitro. The mechanism of degradation of the PDLLA membrane in vivo and in vitro is similar, both represent the simple hydrolyze. The degradation of he composite membrane mainly represent the PDLLA hydrolyze of, chitosan can hydrolyze when there are acid product which is PDLLA's catabolite in vitro.

降解机理探讨：壳聚糖膜体外中性条件下不水解；聚乳酸膜体内外降解机理相似，都表现为简单水解机理；复合膜体外降解主要表现为聚乳酸的水解，壳聚糖在聚乳酸降解后产生酸性产物的条件下存在酸水解机理。

Catechol estrogens, the oxidative metabolites of estrogen, have been reported to be associated with the development of breast cancer.

2-hydroxyestradiol 和 4-hydroxyestradiol是属於邻苯二酚类，为雌激素的主要代谢产物。

The degradation products were mainly glucose and a little cellobiose.

纤维素酶降解产物主要为葡萄糖，并有少量纤维二糖。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
