沉降

Because the settlement of tunnel was very large,the model was applied and good results were obtained in the tunnelling process.

根据某地铁隧道地表沉降变形大的特点，将本模型应用到工程中，模拟结果与实际情况具有很好的吻合性

Under the effect of compressive stress field, asymmetric in north-south direction, the Tianshan orogen upheaved quickly, and the southern part of Junggar basin subsides as it bent under the compressive action.

天山造山带快速隆起是南北向不对称挤压作用的结果，准噶尔盆地则在挤压作用下弯曲而发生沉降，形成南部坳陷区。

It consists mainly of a series of modern uplifts alternating with sudsidence zones.

该体系的主体构造是由一系列呈NNW向相间展布的现代隆起带和沉降带组成。

In the fan delta plain, the sediments, with relatively large grain sizes, jump forward with the thrust of water flow, while, in the front slope, the sediments have relatively small grain sizes, weltering and depositing a-long the slope under the force of gravity, forming typical normal grain size gradation.

扇三角洲平原以水流推力作用为主，沉积物以滚动、跳跃方式搬运，粒度最粗；前缘斜坡以重力作用为主，沉积物顺坡向下滚动、沉积，粒度略细，且具有明显的正粒序特徵；前扇三角洲以浮力作用为主，沉积物为悬移质沉降，粒度最细。

This may be due to the settlement of foundations or to a differential temperature movement of supporting piers.

这种运动可以是由于基础沉降或由于支墩因不同温度变化而产生。

Based on international front and hotspot in atmospheric chemistry and aerosol study, considering domestic characteristics of atmospheric pollution, the laboratory has included main research areas below: atmospheric chemical reaction, aerosol chemistry, photochemical pollution, acid deposition chemistry, atmospheric brown cloud, emission characteristics and emission factors of PM and VOCs emitted from various sources, indoor air pollution and its control techniques, health effect of particulate matters, and so on.

Different chemicals such as KH2PO4,(NH4)2CO3, KCl, CuSO4, Na2MoO4, Na2WO4, FeCl3, K2Cr2O7, acetic acid and sludge, were added to the lysimeters respectively and the settlement rate of refuse surface and generation rate of leach...

根据沉降速度与时间的函数关系，推算了填埋场稳定化时间。实验结果表明，氮、磷和钾的加入促进了垃圾降解，从而缩短了稳定化时间。其它化合物的加入对降解则影响不大

During the acid washing process of steel tube,it can produce much acid wastewater which contains metal ions.

含有金属离子成分的酸性废水一般采用石灰乳中和法进行处理，但该方法处理后生成的沉淀密度较小，沉降效率较低，外排水水质变化较大。

The SVI of the activated sludge was less than 90 mL/g during the experiments.

整个试验过程中污泥体积指数均小于90 mL/g，污泥的沉降性能良好。

The effects of magnetic seed, aluminum sulphate and pH value on phosphorus adsorption, precipitation and coagulation were surveyed. The results made it clear that Al ion as precipitant and coagulant was the main effect factor on P removal; as adsorbent magnetic seed had little effect on P removal, but made the phosphate precipitate sink faster; pH value had effect on both precipitation and adsorption.

研究了磁种、硫酸铝、pH值等对磷的吸附、沉淀、凝聚的影响，结果表明：铝离子的沉淀作用是除磷的主要原因；磁种的吸附作用对除磷的贡献较小，但使磷酸盐沉淀物的沉降性能大大提高；pH值既影响沉淀作用，也影响吸附作用。

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。
