黄土

Water is the primary limiting factor for plant growth and crop production in the loess hilly-gully area of the Loess Plateau.

水分是制约黄土丘陵区农作物正常生长和农业生产的关键因子。

In order to give their labouring parents a better life and hopefully help to make their impoverished hometown prosper, two brothers leave their warm yellow-earth village to head for a civilised city. With a little money in their pockets they brave themselves for hardships in the hope that they will save enough to buy a tractor back home one day.

一对乡下兄弟，为了能够让面朝黄土背朝天的父母减轻劳作的压力，为了让三餐不计的家里人能过上好日子，为了能让家乡有朝一日能像城市一样的繁华----，离开了那贫瘠却坦诚的黄土地，怀揣着几张皱巴巴的钱币和殷切的期待来到一座&文明城市&打拼，只为拥有一台&拖拉机&的梦想。

All this had struck Shangguan Jintong, a man just released from a yellow-earth shanty in a labor reforming farm, as novel and foreign. His heart became more leaden.

这一切，都让刚刚从劳改农场的黄土屋里钻出来的上官金童感到新鲜、陌生，那惴惴不安的心情更加沉重了。

The results show that the prediction errors of the variance and curve shape between the quasi consolidation model and hyperbolic model are small and with the verification of the hyperbolic model, the quasi consolidation model can give a better prediction of post-construction settlement of the loess subgrade.

结果表明：双曲线模型与似固结模型的误差平方和与预测曲线的误差均较小，能较好地反映黄土路基工后沉降的规律，两者相互印证，提高了工后沉降预测的可靠度。

Based on the long-term monitoring data of post-construction settlement of the loess subgrade of the LanzhouWuwei Line Ⅱ, the quasi consolidation model was set up and contrasted with other models such as the Poisson model, index model, logarithm model and hyperbolic model.

利用兰武二线黄土路基工后沉降的长期观测数据，提出一种新的分析预测模型——似固结模型，并与泊松模型、指数模型、对数模型、双曲线模型的预测结果进行对比分析。

During this period, variance contribution rate of quasi 100 ka cycle is up to 37.44%, and quasi 100 ka cycle has a leading role.

P。也发现地球轨道三要素中的偏心率准100 ka周期2、1 ka岁差周期及55 ka、8.3 ka、3.5 ka非轨道准周期，偏心率准100 ka周期具有主导地位（方差贡献率达37.44%）；3尽管黄土记录的东亚夏季风100 ka周期的产生机制已有多种假说，古气候学界还是普遍认为它产生于某些尚不清楚的过程，有待进一步研究。

In the Loess Plateau area, planting plantation had much help for the improvement of the nutritional element content, such as soil organic matter, total nitrogen, total phosphorus, available nitrogen and quick-acting potassium, and different plantations had different enhancement degrees.

结果表明：在黄土高原地区，种植人工林后能增强土壤腐殖化作用，促进土壤有机质的形成发育，对土壤的有机质、全氮、全磷、及碱解氮、速效钾等营养元素含量提高有很大帮助。

Fallow lands of winter wheat in the southern part of loess plateau with an annual precipitation of 632mm were selected as the study object, Field and lab experiments were carried out during two wheat growth periods to investigate the correlations between N2O emissions and its influential factors, quantitative model and energy characteristics.

本研究以年均降水量为632mm的黄土高原南部旱作区冬小麦—休耕地土壤为对象，通过两个小麦生长年度不同处理的大田试验和相应的室内实验，对土壤N_2O排放量及其与影响因子的关系、定量模型和能量特征进行了系统研究。

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.
