Based on results in this study and our previous findings, we believe that differences of ATPase activity in cells of aloe leaf Chlorenchyma reflect the differences of physiological status and function of aloe leaves, regulating and/or enhancing ATPase activity is an important cyto-physiological mechanism of Si-alleviated effect on salt injury to aloe.

叶同化组织细胞中ATPase活性的差异性反映着芦荟叶生理状态和功能的差异性，可溶性Si调节或增强盐胁迫下芦荟ATPase活性是Si缓解芦荟盐胁迫伤害效应的重要细胞生理机制。

The radio of the length and the weight between in cotyledon and in the whole is corresponding to the degree of stress, which is in favor of root system getting into the deeper to alleviate the stress.

根的长度和干重在总长度和总干重的比例一般与胁迫程度呈正相关关系，以利于其根系深入到盐胁迫程度较低的土壤深层。

The correlation analysis indicated that positive correlations existed between electrolyte exosmosis percentage, MDA content and POD activity in both salt and drought treatments, and significant correlations were also found between electrolyte exosmosis percentage, POD activity and MDA content in NaHCO3 stress.

相关分析表明：不论是碳酸盐胁迫还是干旱胁迫，欧李的电解质外渗率、MDA含量和POD活性存在一定程度的正相关，碳酸盐处理下POD活性与电解质外渗率和MDA含量间达到显著的正相关。

This study was to evaluate the action mechanisms of 6-BA applyed exteriorly on the growth and chilling resistance of oilseed rape seedlings before or under a low temperature (4℃) stress and resuming growth. Results showed that under low temperature, the oil rapeseed seedling was damaged at a certain extent. 5 mg L~(-1) of 6-BA accelerated the growth of seedlings, controled the chemical matter in cell and protected the stabilization of cell membrane, so 6-BA improved the chilling resistance of seedlings.

通过对低温(4℃)胁迫前、低温胁迫后和恢复生长4d后油菜幼苗的相关生理指标研究发现，低温下油菜幼苗受到一定的伤害，但5mg L~(-1) 6-BA通过促进幼苗生长，调节细胞内化学物质，保护细胞膜的稳定，提高了幼苗抗寒性。

Effect of different soil drought stress on the growth and accumulation of soluble substances of Arachis duranensis was studied by potted culture with controlling soil water content.

采用盆栽拉水的方法，研究了不同土壤干旱胁迫程度与胁迫时间对多年生落花生Arachis duranensis生长及溶质累积的影响。

Stomatal restriction was the main factor for the P's decrease in the leaves of both alfalfas under light drought stress, while the non-stomatal restriction was the main factor for the P's decrease in the leaves of these alfalfas under medium and severe drought stresses.

2轻度干旱胁迫下气孔限制是两种紫花苜蓿P降低的主要因素，中度和重度干旱胁迫下非气孔限制是P降低的主要因素。

Cd inhibited the absorption of Mg and Mn in roots. However, Cd could stimulate the absorption of Fe in roots. Moreover, Cd inhibited the absorption and utilization Mg, Mn and Fe in leaves. 4. Cd inhibited the photosynthesis of Populus clones. Cd showed no significant inhibition to net photosynthesis rate, stomal conductivity and transpiration rate versus the control, under 10μM Cd treatment.

Cd胁迫还对杨树光合作用产生影响，低浓度Cd对杨树光合速率无影响，中高浓度Cd对杨树净光合速率、气孔导度和蒸腾速率等具有抑制作用，而且随着处理时间的延长和Cd胁迫浓度的提高而逐渐加大。

表明对水分胁迫越敏感的生长动态，胁迫历史对它的后效影响越大。

And 50 μmol/L CdCl2 were introduced to the culture solution from the three-leaf stage with treatment duration of 24 days, and no CdCl2 in the culture solution was set as the control.

为了明确镉胁迫对小麦幼苗生理生化指标的影响，选用川35050和山农483两个小麦品种，在水培条件下设置0、30、50 μmol/L 3个处理浓度，研究Cd胁迫下小麦幼苗膜脂过氧化作用、糖氮含量和Cd吸收转运的变化。

Golden Delicious' growed in farmland in Qin'an County of Gansu Province was used as the experiment material.

本研究以甘肃省秦安县大田生长的'金冠'苹果为试材，用正常果树和盐碱胁迫果树对比方法，研究了自然条件下钠盐胁迫对果树整个生育期体内各器官（根系、枝条、叶片、花、果实）钠含量的影响。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
