黄土

Based on the present research results, a method to establish the constitutive law for collapsible deformation is proposed by studding the collapsible loess in Lanzhou....

本文在对兰州地区湿陷性黄土的湿陷变形的研究，在已有研究成果的基础上，建议了一种建立黄土湿陷变形本构关系的方法。

Moreover, the influence of carbonate on the adsorption process was also studied. Under the anoxic condition, the AVS in Guanting Reservoir sediments controlled the partitioning of most of the metal ions between sediments and pore water.

对于渭河潼关沉积物，由于在组成上和黄土有很大的相似性，本文建立了与黄土类似的表面络合模型，并成功的模拟了潼关沉积物的表面酸碱反应特性及其对铜和镉的吸附特性，同时探讨了碳酸盐在吸附中的影响。

The compression test and triaxial test of the original loess and remolded loess are carried out.

摘要本文进行了原状黄土和重塑黄土的压缩和三轴试验。

Loess a company's existing quarry, a processing plant, Machinable Loess stone wall and floor tiles, mosaics, loess powder, and other stone products loess.

公司现有一座黄土石矿，一个加工厂，可加工黄土石墙地砖，马赛克，黄土石粉，其他黄土石产品。

Why could people there with yellow dirt all-over merge into the background of loess land so easily?

是人人化了黄土，还是黄土土化了人？

It not only arains natural resources day by day and decreases the biological diversity,but also seriously prevents the Loess platean's area econnomy from developing continuingly,then threatens the local people's living and development,thus,the study and governing of biological degeneration should be regarded seriously.

中文摘要：摘要：生态退化是目前黄土高原所面临的主要环境问题，它不仅使自然资源日益枯竭、生物多样性不断减少，而且还严重阻碍黄土高原地区经济的持续发展，进而威胁当地人民的生存和发展，因此，对生态退化的研究和治理应给予万分的重视。

Balladry civilian is a day with feeding, chinese farmer is forever on loess ground rehabilitate, they use their arduous sweat, dare be with laborious He Yong in loess ground dig is fed, they are like willing ox on loess ground hard land is cultivated, sow, breath, the hope trades the get one's own back of a land, long to come the joyance of the bumper harvest.

民谣民以食为天，中国的农民世世代代在黄土地上休养生息，他们用自己辛勤的汗水，用勤劳和勇敢在黄土地里刨食，他们又像老黄牛一样在黄土地上艰难地耕耘、播种、喘息，希望换来一份土地的回报，盼来丰收的喜悦。

In Project A, grain shortage will not appear in the corrasive region of Loess Plateau on the whole. But in order to achieve an equilibrium of demand and supply, loess hill regions must import grain from the Loess Platform region.

从A方案看，就黄土高原水土流失区整体而言将不会出现粮食短缺；但具体到分区而言，黄土丘陵区必须通过粮食调入才能满足本区需求，而黄土台塬区则有一定盈余。

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

It is concluded that granulometric composition , microstructure, specific moisture content, compacting power efficiency are the main factors influencing loess compacting.

指出黄土的粒度成分、显微结构、含水率、击实功率是影响黄土压实的主要因素。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
