According to the result of artificial rainfall, the character and factors affectedby soil, rainfall, chemicals, slope length, slope gradient and field mangment practices, for rainfall, runoff,infiltration, soil erosion and soil chemicals, such as NO_3~-, NH_4~+, PO_4~(3-), K~+ and Br~-, are investigated. Thedeterminate methods, influence factors and practical application of the mixing zone depth are also researched.The results can enrich the dynamics of soil, water and nutrient transport, evaluate the soil water and fertilizerefficiency, and theoretically benefit the research of agricultural NSP on loess hill slope. 1. According to the surface transport experiments of soil chemicals under the non-satuation soil and watererosion condiction, for adsorbed PO_4~(3-) and K~+, the time of sheet erosion and rill erosion initiation is coincidentthat of chemicals content in surface runoff climbs, and then their abundant export by surface runoff is urged.

本文以黄土坡地为研究对象，通过模拟降雨试验，研究土壤因素、降雨因素、化学物质理化性质、坡长坡度因素和农田管理措施等对坡地降雨—产流—入渗—土壤侵蚀—农田NO_3~-、NH_4~+、PO_4~(3-)、K~+和Br~-地表迁移的影响，研究非饱和土壤和水蚀条件下混合层深度的确定、影响因素和模拟，探讨其在黄土坡地的实际应用，为丰富坡地水分养分迁移动力学、提高旱地土壤水分养分利用率和深化农田非点源污染研究提供理论依据。

In this study, the actual temperatures in different solder joints were below 100°C, which did not induce magnificent atoms thermodiffusion to submerge electromigration.

数值模拟表明，电流密度聚集是产生电迁移失效的根本原因，焊点的实际温度低于100°C，避免了高温下原子热扩散对电迁移的干扰。

Measurements and Main Results: ATRA stimulated NB4 cells to transmigrate toward the A549 cells in a time- and dose-dependent manner. Replacement of A459 condition medium by its original medium abrogated this transmigration.

测量与结果：全反式维甲酸会刺激 NB4 细胞迁移至 A549 细胞，并且具有时间与剂量之效应，若是以单纯的培养液取代 A549 细胞之条件培养液，则 NB4 不会有迁移的作用。

The mechanism of migration and transformation for inorganic and organic pollutants in vadose zone and its research present situation at home and abroad are discussed;the mathematic model of simulated pollutants migrating and transforming rule in vadose zone and its applied qualification are explained,thus a foundation is laid for controlling the pollutants of vadose zone and underground water.

评述了包气带中无机污染物和有机污染物迁移的机理及国内外研究现状，说明了模拟污染物在包气带中迁移转化规律的数学模型及其应用条件，从而为控制包气带及地下水的污染奠定了基础。

In the article, considering the potentially severe pollution of the subsurface environment from the low level radioactive waste , the dynamic integrated transport model of low level nuclide in vadose and saturate zones has been established and is used to predict the dynamic action of the nuclide in a disposition spot.

针对处置库中低中放核素释放对地下环境潜在性污染的严重性，建立了核素在包气带和含水层中联合迁移的数值模型，利用所建立模型对某一处置场核素迁移的动力学行为进行环境预测。

But scientists are still working out the details of how the planet was peopled, such as who went where, and when.

但是，科学家们仍然在研究人类曾经在地球上分布的详细情况，如：何人迁移到何地，又是在何时进行迁移的，等等。

Just why they took so long to travel north is not clear, but many researchers have suggested that the bone-dry Sahara Desert was a major barrier to migrations from the south.

至于人类究竟为什么在这么长时间之后才开始朝北迁移，原因尚不清楚。然而，许多研究人员提出，极为干燥的撒哈拉沙漠是自南向北迁移的主要障碍。

Some developing countries are both recipients and senders of migrant workers.

一些发展中国家既是劳动力迁移的输入国，又是劳动力迁移的输出国。

RESULTS The abnormal shifting of PCR-SSCP single-strand DNA were observed in 3 out of 11 cases of cholangiocarcinoma.

结果11例胆管癌中，3例胆管癌样品PCR－SSCP单链电泳带迁移异常，依据DNA单链构象与分子电泳迁移的关系，胆管癌p53基因5～8外显子的突变率为27％；6例有p53蛋白异常表达，阳性率为55％。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
