Finally, based on the fundamental solutions of Biots consolidation of transversely isotropic saturated multi-layered soils, the Fredholm integral equation of second kind for the interaction between transversely isotropic saturated multi-layered soils and rectangular piles is established, the relevant numerical analysis is also carried out.

最后，基于横观各向同性层状饱和地基Biot固结问题的基本解答，建立了横观各向同性层状饱和地基与方形单桩、群桩共同作用问题的第二类Fredholm积分方程，并进行了数值分析与计算；通过将矩形刚性基础基底划分成若干个大小相等的矩形网格，用矩形均布荷载表示网格的基底反力，并利用已获得的横观各向同性层状饱和地基Biot固结问题的基本解来求解每个矩形网格的柔度系数，然后根据刚性基础与层状饱和地基的接触条件和其本身的静力平衡条件，求解分析了横观各向同性层状饱和地基与刚性矩形板的共同作用问题。

Paul Kreutzer: The first question, the answer gets a bit difficult, it looks like an issue of the applicant, the applicant must first come to interview in person to the visa officer to explain your situation, explain why you go to the U.S., how do you like lead us to believe you will come back. Their home girls spent six years in the United States did not come back, its the girls did not come back, how to visa officer that the parents come back.

各位新浪网友，如果你们刚刚进入新浪嘉宾聊天室的话，大家会很清楚，在5点到6点钟这个时间段里面，时间已经过了一半，我们请到美国签证处的副处长Paul Kreutzer先生，在为网友解答赴美签证的事宜，有不少网友提出的问题都被解答了，有不少问题都在等待之中，希望网友耐心一点，有的问题已经做了总结性的提问，你们能够在回答过的问题的答案中找到自己需要的答案。

The result showed that,if only the necessary but insufficient condition,the equilibrium condition ,was adopted to deal with the infinite uncertain boundary condition,the solution to the stress was non-unique due to the fact that the boundary problem here was a mal posed mathematic problem.

通过两个典型的半无限体实例，对水平表面作用无限均布压力下弹性地基的应力和位移解答进行研究，结果表明：对边界条件不明确的无限边界仅采用解答的必要非充分条件——平衡条件来等效处理，其应力解答不是唯一的，因为此时该边值问题不是一个适定的数学问题。

Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.

介绍了Vesic关于圆孔扩张问题的解答，其中包括柱形孔扩张问题和球形孔扩张问题，并应用柱形孔扩张理论分析了饱和软土中的沉桩挤土效应问题；在常规三轴试验成果的基础上，采用三折线模型模拟具有应变软化性质的岩土材料的应力应变关系曲线，分析了在应变软化土体中沉桩时桩周土的位移场、应力场和应变场的变化，得到了解析解答；分析了静压桩的沉桩机理，并利用球形孔扩张理论，视桩端处的挤土为半个球形孔的扩张，分析了桩端处土的位移场、应力场和应变场的变化，并根据最终扩张压力计算出沉桩时的桩端阻力，可作为压桩力的估算。

斐波那契注重问题求解，以设计出尽量简单的算法求出解答为目标，利用欧几里得《原本》定理进行几何证明代数方法合理性的过程中，不追求逻辑论证的完美，而是凭藉巧妙的几何图形构造，简化计算过程，从而得到问题的解答。

Other parts include language models (the ability to handle phrases, synonyms, diacritics, spelling mistakes, and so on), query models (it's not just the language, it's how people use it today), time models (some queries are best answered with a 30-minutes old page, and some are better answered with a page that stood the test of time), and personalized models (not all people want the same thing).

其他部分包括语言模型（处理短语、同义词、符号、拼写错误的能力等），查询模式（我们不仅要考虑语言本身，还要考虑人们如何使用语言），时间模型（有些问题要靠互联网上仅仅产生才三十分钟的最新网页来解答，而另一些问题则需由经受了时间考验的网页来解答），和个性化模式（并不是所有人都想得到同样的答案）。
