交界

These issues mainly include simulation offlexible soil container, selection of dynamic constitution model of soil, simulation of the changing-status non-linearity on soil-structure interface, meshing, treatment of reinforcements in structure,using of symmetry principle and so on.

按照本文的建模原则和计算方法，对土-桩基-结构相互作用体系振动台试验进行三维有限元计算分析，计算中土体采用等效线性模型，利用面-面接触单元考虑土体与结构交界面的状态非线性。

Based on the large-scale model test on soil-pile-structure interaction, as a part of the project financed by nature science national fund, analysis of soil-foundation -structure dynamic interaction (NO.50278033), some issues about modeling of soil-structure interaction system are discussed in this thesis. These issues mainly include simulation of soil infinity, selection of dynamic constitution model of material, simulation of the changing status nonlinearity on soil structure interface, meshing, using of symmetry principle and so on.

结合国家自然科学基金课题《地基-基础-上部结构相互作用体系动力特性研究》(NO.50278033)，以大比例桩筏基础框架模型试验为基础，运用通用有限元软件MARC，首先对土—框架结构动力相互作用体系进行有限元计算建模的一些问题作了研究，主要包括粘—弹性人工边界的施加、土域范围的选取、材料本构模型的选用、土体与结构交界面上状态非线性的模拟、网格划分以及对称性的应用等。

Marry one of the twins and then the plantations will run together and Jim Tarleton and I will build you a fine house, right where they join, in that big pine grove and

嫁给双胞胎中的一个，我会拿种植园给你做嫁妆，吉姆·塔尔顿和我将为你建一座好房子，就在两家交界的地方，在那片大松林里——

The Canadian Shield and rugged western mountains experience subarctic climates, resulting in a near empty north—an estimated 75 percent of Canadians live within 161 kilometers (100 miles) of the U.S.

这个盾和西部的山区是亚北极气候，导致北部空旷－大约75%的人口居住在美加交界的161公里内。

In fact, the Chinese Navy and the Indian Navy, the real swords and guns to knives to guns to fight a large, the occurrence of such opportunities may be more difficult to overcome even more of their own, although the land at the junction of the two countries, but at sea, the fleet between the two countries must be far around the Straits of Malacca in order to meet; Moreover, I can honestly say that the history of China and India is not belligerent or aggressive habits of the country, then they are strongly influenced by western colonial gunboats of bullying, but it had no predatory sea resources and wealth of others from the history of fat, so, it is apparent that Chinese and Indian Navy at sea to fight a real, and the war or the use of teams to the size of nuclear submarines and aircraft carriers, it seems a fairy tale.

其实，中国海军和印度海军，真要刀对刀枪对枪地大打一场，这样的发生机遇可能比战胜之本身的难度更大，虽然两国陆上交界，但在海上，两国的舰队必须远绕马六甲海峡才能相遇；而且，说实话，中印两国历史上都不是有好战或侵略习性的国家，当年它们都深受西方殖民主义坚船利炮的欺负，但也都无出海掠夺他人资源和财富自肥的历史，所以，表面看来，中印两国海军在海上真正打一场，并将战争升组到到动用核潜艇和航空母舰的规模，似乎天方夜谭。

For stable surface waves, there exist a frequency threshold, a power threshold and two cross-jumping powers.

研究了两非线性反铁磁晶体交界面上稳定传播的电磁表面波的传播特性。

In the early 19th century, it was thought that canals, in which boats and barges were pulled by mules trudging along an adjacent towpath, would revolutionize commerce and travel.

在19世纪早期，人们认为是运河变革了商业贸易与交通，骡子们拉着运河中的船沿着交界的牵道一步步地跋涉着。

The engine-feed system interface is at the turbopump inlet flanges.

发动机与供应系统的交界是在涡轮泵的进口法兰盘处。

The results show that the angular distribution of the total differential cross section at zero degree increases and the position of oscillation minimum of the same order gradually shift towards small scattering angle along with the increase of the incident isotope He atom mass at identical collision energy. And crossing angle between the elastic and total inelastic DCS gradually decreases and the total inelastic DCS gradually increases.

结果表明：在相同碰撞能量时，随着同位素氦原子质量的增加，总微分截面在0°时的角分布逐渐增大，同一级衍射振荡极小值位置逐渐向小散射角方向移动；弹性与总非弹性截面交界角逐渐减小，总非弹性截面逐渐增加。

Wednesday March 12, 2008: We barreled down the lakeside and up through the cow pastures and snowy peaks between Zurich and Zug.

我们的汽车沿着湖岸飚飞，接着又在苏黎世和苏格交界的奶牛牧场和雪峰之间崎岖穿行。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
