The author estimates that in the early Northern Song, more than 100,000 Tangut people crossed over to Song and moved to the border areas between the Song and Xixia, living in the region from Linfu in the east to Huanqing in the west.

北宋初期估计有十余万党项民众先后内附于宋，这些内附党项集中分布在东起麟府、西到环庆的宋夏沿边地区。

Then, aspartic acid was used for the enrichment of tryptic peptide mixture of C57BL/6J mouse liver lysate and good results were also obtained which demonstrated that aspartic acid was a promising non-specific binding inhibitor for complex biological samples.

将添加天冬氨酸的二氧化钛富集体系应用于鼠肝全蛋白质磷酸肽的富集中，同样取得了很好的效果，表明天冬氨酸在复杂的生物样本的磷酸肽富集中也同样具有良好的应用前景。

This is a future in which China turns inward and focuses on driving national innovation, usurping foreign intellectual property, developing regional standards, and creating heavily regulated protectionist markets.

在这种模式之下，中国会趋向于内向发展，集中精力推动国家创新，吸收各国的人才资源，建立他们的区域性标准，形成监管更严格的自我保护市场。

Vaccinium spreads widely from tropic to the Arctic Circle. It is distributed mainly in southwest area in our country.

越桔属植物分布广泛，从热带一直到北极圈都有，在我国集中分布于西南几省。

Moreover, this paper makes an effort in incorporating theCosserat theory in the VCFEM for the elastic-plastic analysis of heterogeneous materialsbased on the PVP. The chapters are divided as follows: In Chapter 1, the author summarizes the study on the equivalent mechanics properties ofheterogeneous materials (including the development of the universal relationship which isirrelevant to the micro structure, the discussion of the limitations of the effective moduli, thecomputation of the effective properties of heterogeneous materials with the micromechanicsmethod and the FEM, and the equivalence of the heterogeneous micropolar materials) and thepresentation, the evolution, the corresponding numerical studies of the Cosserat model and itsapplications in engineering.

本文基于参数变分原理，构建了Cosserat体弹塑性有限元分析模型并用于求解应力集中和应变局部化问题；利用Voronoi有限元法提出了适用于非均质材料宏观弹塑性性能计算的参数二次规划算法；进一步将Cosserat模型应用到Voronoi有限元法中，提出了基于Cosserat理论的Voronoi杂交有限元法，并采用参数变分原理进行新模型的分析计算。

This project only sets out to initialise DirectX and place the developer in the position where they can concentrate on what they want to do and not on messing about with Microsoft's DirectX code.

这个工程仅仅设定用来初始化directx并且可以把开发者置于一个他们可以集中注意力于他们想要做的事情上而不至于和microsoft的directx代码相混淆。

Hen walking on a high wire, you should concentrate on the way your body moves in the air.

走钢丝时，你要集中精力于身体在空中的移动方式。

The idea behind the newly created posts was that political appointees would provide more accountable government than bevies of civil servants.

当前，本地评论员认为，争议的焦点集中在政府领导人身上，相对于普通市民来说，他们的护照更能反映出其政治忠诚度。

Currying has its origins in the mathematical study of functions.

currying来自于对函数的数学研究。1893年Frege发现可以把注意力严格集中到只有一个参数的函数上。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面，靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内，朝水面方向各测点气泡个数分布最大值呈减小趋势，而其对应尺寸则呈现变大趋势；在靠近槽底，个数分布表现得比较集中，而在水面附近气泡个数分布曲线表现得低而平缓；实验条件下，整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方；气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大，且越接近掺气水流的水面，增加速度越快，最终趋于无穷大；气泡总数在掺气发展区内是沿程增加的，当掺气水流发展到一定程度后气泡总数就基本保持不变了；在同一断面上，各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。
