土壤发生

The main reason for these was ascribed to the replacement effect of rare earth elements to heavy metal.

实验发现重金属的形态和积累的确受到外加稀土的影响，引起变化的原因主要归结为外加稀土元素发生的替代反应，这种替代作用表明施加稀土肥干扰了土壤中的金属平衡，值得进一步的研究。

Therefore, the aim of these treatments is to provide a mature, stabilized organic material in which the humification process,Which typically occurs under natural soil conditions, has started and has reached an adequate degree with the production of "real" humic substances.

因此，这些处理的目的就是要提供一个成熟的稳定的有机物质，在其中腐殖化作用（自然土壤条件下的典型现象）已经发生而且已经达到一个足够的程度，能产生真正的腐殖质。

While,isogram of soil water content became more sparse,the number of closed center of isogram decreased and the location of closed center of isogram moved with changing of scale.

在尺度变化的情况下，随着尺度的变大，土壤水分的等值线变得越来越稀疏，闭合中心的数量逐渐减少，位置发生移动。

This phenomenon to some extent explains the ability of the migratory locust to withstand low temperature.

特别是在北方地区，越冬蝗卵要在土壤中度过 7个多月的时间，它们能否抵抗住生存环境的寒冷，这对下一季节的发生是至关重要的。

Drought-resistant germplasms were mainly origin in low temperature, frequently drought, poor soil region, such as Wangmo, Luodian, Rongjiang, Ziyun and so on.

抗旱种质多来源于贵州省低热的望谟、罗甸、榕江、紫云等干旱频繁发生、土壤贫瘠的地区。

The corrosion rates of mild steel in soil was studied by means of polarization curve measurements on steel specimens with various extent of corrosion in laboratory.

1前言土壤中钢铁的自然腐蚀是钢铁在外界侵蚀性介质的作用下发生电化学和化学过程而受到的破坏。

Field germination, nodulation status and growth parameters were varied significantly in the soil amended with sludges in comparison to control.

与对照幼苗相比，混合污泥的土壤中生长的幼苗田间发芽、分枝状况及其他生长参数均发生了显著变化。

The studies show that Ginseng red coating root disease is a non infectious disease.The direct cause is that under the special soil environment,the Fe2＋,Fe3＋ around the roots is fixed,oxidized and deposited in phellem of the roots,and it cause the changes of the regular physiological and biochemical activities in Ginseng plant,it is a comprehensive action of many factors.

结果表明：人参红皮病为非侵染性植物病害，其发生的直接原因是在特定的土壤条件下，Fe2＋、Fe3＋在参根周皮木栓层固定、氧化沉积和参株不正当的生理生化活动综合作用的结果。

The results were as follows: when the soil water content was reduced, the modality characteristic was changed, cell membrane permeation and praline content increased, the relative water content of leaves decreased under stress.

结果表明：随着土壤含水量的降低，3个品种的外部形态均发生变化，叶片相对电导率和脯氨酸含量增加，叶片相对含水量降低，且各指标变化幅度因树种的不同而不同。

Most evidence suggests that this process can only occur when the soil is saturated and transpiration is low, but the critical thresholds at which root pressure is inhibited have not been established experimentally.

大多数的证据意味着当土壤是饱和的，而且散发是低点的时候，这一个程序才能发生，但是紧要关头的门槛在哪一个根压力被禁止还没有被实验式地建立。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
