叶片中Spm和Spd及根中Spm含量在一定浓度范围内，均随NO3浓度的增加而升高，当NO3浓度高于140 mmoL/L时，其含量反而开始降低；叶片中Put含量均明显低于对照。

Treatments with 20μmolL^(-1) CoCl2 and 20μmolL^(-1) AVG did not influence the contents of putrescine, spemidine, spermine, chlorophyll, and the production rate of reactive oxygen species. However, after 12h heat stress of 45℃, treatments significantly promoted the above values.

但经45℃高温胁迫12h后，20μmolL^(-1) CoCl2与20μmolL^(-1) AVG溶液处理显著提高了上述3种多胺的含量，减缓了抗氧化酶活性的下降，对活性氧水平及脂质过氧化水平的增加也起到了有效的抑制作用，这些改变可能对叶绿素降解的减少及膜稳定指数下降的减轻发挥着重要的作用。

The contents of putrescine were apparently higher than the control, then decreased with the increase of lead mass concentration and the time of treatment.

黄瓜幼苗叶片精胺和亚精胺在处理第5d时高于对照值，茎中精胺和亚精胺含量在处理第7d高于对照值，而其它时间内的都低于对照值，而且其含量均随铅质量浓度的增加而呈下降趋势；过氧化物酶活性变化与内源多胺含量（腐胺、精胺和亚精胺之和）的变化相似，表明铅胁迫能改变黄瓜幼苗内源多胺的含量和调节过氧化物酶活性，从而影响着黄瓜植株的生长。

该方法使我们能更快更正确地同时检测头发样品中的腐胺、精脒和精胺，能在临床早期诊断和癌症预防方面有一定帮助作用。

The results showed that the tested results by PCR and HPLC were identical, the 22 fine Oo strains screened from grape production area produces no histamine, tyramine, nor putrescine, therefore, from the point of view of biogenic amines, 22 fine Oo strains screened in China possesses fairly high safety in metabolically biogenic amines.

结果表明，PCR检测结果与HPLC测定结果一致，从我国葡萄产区筛选的优良酒酒球菌均不产生组胺、酪胺和腐胺，从生物胺角度，我国筛选的22株优良酒酒球菌具有较高的生物胺代谢安全性。

Experiments showed that the contents of putrescine、spermidineand sperminein normal ovules were higher than those inabortive ones during the whole embryogenetic process.The highest levelswere reached 7 days after anthesis,with Put being the richest of thethree,then they declined.

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。
