沉降

The episodic rifting processes of the Tertiary representative rifted basin s in East China were revealed on the basis of the basin filling records,tectonic framework and subsidence history.

应用盆地充填记录、盆地构造特征和盆地沉降史等信息，揭示了中国东部第三纪典型断陷盆地的幕式构造演化过程。

These are proper rear boundaries of continental margins, the geodynamics of which are characterized by rifting on shelves, continental slopes, and marginal oceanic depressions.

它们位于大陆边缘区的后缘，其地球动力学作用以大陆架、大陆斜坡和边缘海沉降区域的裂谷作用为特征。

The N input from rainfall in HPA was about 3 to 4 times higher than that in LPA and CK. However, the biomass of vegetables in HPA was decreased by up to 40%, when compared with that in CK, thus leading to a significant decrease in N output through crop harvesting. As a result, a large proportion of N was sequestrated in the soils subjected to acid rain, which subsequently enhanced nitrate leaching posing a risk to water environment.

在酸沉降重污染区，降水输入系统的氮远大于轻污染区和对照区（约3~4倍），同时因酸雨危害，蔬菜产量明显低于对照区，仅为对照区产量的60%，使系统中通过作物收获的氮输出减少，结果导致大量氮滞留于土壤中并以硝态氮等形态淋失，给水环境带来了氮污染风险。

Consolidation settlement occurs mainly in clays or silts.

压缩沉降主要出现在粘土或粉沙中。

It is apparent that the higher-density slurries with a lower water/cement ratio have essentially no particle settling.

显而易见，高密度水泥浆具有较低的水/水泥比率基本上没有粒子沉降。

Finally, the process experiment for treatment polymer flooding produced water was done in oilfield, the process parameters were determined, and the treatment ef-fects were evaluated. The experimental results indicated that air sparged hydrocyclone in-tegrated the hydrocyclone and floatation.

研究结果表明，气携式液-液水力旋流器可以发挥旋流与气浮的协同效应，与传统的两级沉降除油工艺相比，除油效率高，停留时间短，具有较好的推广应用前景。

A first decline was sunken to provide access to the ore body and trail mining was carried out in different stopes.

第一次沉降为我们提供了接近矿体的机会，公司在不同的采矿场进行了试采。

The approach embankments, abutment walls and wing walls were constructed and surcharged prior to installation of the bridge seats, with the resultingload producing 8.5 inches of settlement.

在安装桥座前，引桥路堤、桥台墙和翼墙已经施工和对地基进行了预压，总沉降8.5英寸。

1Public fill is sometimes stockpiled as surcharging on newly reclaimed land to accelerate the settlement process.

有时公众填料会被贮存在新填海区的土地上作为预载的用途，以加速其沉降。

Four nitrogen addition treatments i.e, null nitrogen level, low nitrogen level (LN, 50 kg N hm-2 a-1), moderate nitrogen level (MN,100 kg N hm-2 a-1) and high nitrogen level (HN, 150 kg N hm-2 a-1), were established in the forest. All nitrogen treatments were carried out in triplicates.

通过原位进行低氮(LN， 50 kg N· hm-2· a-1)、中氮(MN， 100 kg N· hm-2· a-1)和高氮(HN， 150 kg N· hm-2· a-1)处理，研究了川南天然常绿阔叶林土壤酶活性特征及其对模拟N沉降的响应。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
