Lactic acid is the main metabolite product of muscle exercise; it is an important sign to evaluate the fatigability of an organism.

血乳酸作为肌肉活动的主要代谢产物，是评价机体疲劳的重要标志。

The traditional commercial law is only the distinctive production under the feudal separation lasting for a long time in the Europe in the history, where the centralized countries lack of unity, and the political powers and rights distributed among other forces of King, feudatory and church. Its closure and particularity gradually disappeared after being brought into the national jurisprudence. But the scholar s vision had not yet been extended besides the civil law and commercial law, which is the historical origin and main cause of the afterwards problems of the civil and commercial unity and separation argument was difficult to draw a conclusion.

传统商法仅仅是历史上欧洲这一特定地区在缺乏统一的中央集权国家，政治经济权力分散于国王、封建领主、教会几大势力，封建割据长期存在这一特定环境下的独特产物，其封闭性和特殊性在纳入国家法的体系后逐渐丧失；但是学者的视野又没能拓展到民法、商法之外，这是后来民商合一与分立之争长期难成定论的历史根源与主要原因。

Its research areas include floriculture and fruit production; plant breeding and genetics, crop, and plant physiology; and natural products chemistry.

其主要研究区域包括花卉栽培和水果产量、植物培养和遗传学、农作物、植物生理学、自然产物化学过程等。

The composition of DDT indicates that the residues include the DDT used before forbiddance and their degrading products as well as a small amount of DDT used recently.

DDT的组成表明，土壤中DDT主要是过去输入环境的DDT及其降解产物，但近期仍有少量的DDT输入。

The pyrolysis characteristics of typical agricultural biomass were investigated using a tubular reactor coupled with a Fourier transform infrared analyzer.

采用管式反应器与傅里叶变换红外分析联用技术进行了生物质热解特性及主要气体产物释放规律的研究。

The effect of Fusarium metabolic product in the soil on the soybean root was researched mainly.

主要研究了土壤环境中镰孢菌代谢产物对大豆根部的影响。

The ORF2 gene is the most important protein-code gene for porcine circovirus, and is the main gene differing porcine circovirus typel from porcine circovirus type2 (PCV2). To construct a specific PCR detecting method, we designed a pair of primers to amplify a partial fragment of ORF2 gene from PCV2, referring to fifteen strains complete genome published in Genbank. The PCR product was about 0.67kb in size detected by gelose gel electrophoresis.

猪圆环病毒的开放阅读框2(ORF2)是其主要结构蛋白的编码基因，也是区分猪圆环病毒1型(PCV1)和猪圆环病毒2型(PCV2)的重要基因，本研究参照GenBank已发表的15株PCV2基因序列，设计合成一对引物，对PCV2的ORF2基因进行PCR扩增，产物经琼脂糖凝胶电泳，呈现一条大小约0.67kb的特异条带，经条件筛选，建立了猪病料中PCV2感染的PCR检测方法。

The results show that: 27 compounds were identified at 600℃, and most of them were alkenes, alkanes, acids, alcohols and phenolic substances; geraniol was identified, and its relative content was 3.6, which shows that geranyl 8-methoxycoumarin-3-carboxylic acid ester can release a certain amount of geraniol at smoke temperature; geranyl 8-methoxycoumarin-3-carboxylic acid ester can improve and modify the flavor, enhance the notes of sweet aroma and bean aroma, and reduce the biting taste of cigarette smoke.

结果表明，600℃时，8-甲氧基－香豆素－3-甲酸香叶酯的热解产物中共鉴定出27种成分，主要为烯类、烷类、酸类、醇类、酚类；鉴定出香叶醇，且相对峰面积3.6，说明8-甲氧基－香豆素－3-甲酸香叶酯能在卷烟燃吸温度下释放出一定量的香叶醇；8-甲氧基－香豆素－3-甲酸香叶酯具有改善和修饰卷烟香气，增加甜韵和豆香香韵，减轻刺激性的作用。

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。
