In corn grouting stage, Trend of photosynthesis is almost the same as seeding and jointing stage under soil Naphthalin pollution stress.

从土壤萘污染对玉米的各个生理生化指标看，低浓度土壤萘污染胁迫对玉米地上

Influence on corn DNA methylation frequency and half DNA methylation frequency is stronger under soil Naphthalin pollution in seedling and grouting stage, this is other mechanism of siol Naphthalin pollution stress.

这可能是土壤萘污染胁迫影响玉米生长发育的一种机制。

Nymphoides peltatum, a floating macrophyte was used as experimental materials, the contents of nutrient elements were obtained by inductively coupled plasma spectroscopy, the effects of exogenous PAs on Zn accumulation and other nutrient element absorption of plant leaves under Zn stress were observed.

方法］以浮水植物水荷花为试验材料，采用电感藕合等离子体发射光谱法测定各种元素含量，研究了外源多胺对锌胁迫下植物叶内锌富集及其他营养元素吸收的影响。

Increase in SOD and POD activities in Paeonia suffruficosa leaves enhanced the resistance to drought stress.

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。
