The nonlinear Winkler-Kelvin sub-grade model is adopted in this simplified model and the complicated 3-D problems of the soil-single piles dynamic interaction are simplified to the 1-D, that is to say, the lateral nonlinear acting force of the soil to the pile shift is simulated with thehorizontal nonlinear springs which have the continuous uniform distribution, while the nonlinear spring restoring force is described by the deteriorated Bouc-Wen model; the radiation damping and material damping due to the energy dissipation and inner friction in the soil are displayed with the dashpots which are in parallel with the horizontal nonlinear springs.

该模型采用非线性Winkler-Kelvin地基模型，将复杂的地基土-单桩动力相互作用的三维问题，简化为一维问题，即，地基土对桩轴的横向非线性作用力，由随深度均匀分布的水平非线性弹簧模拟，非线性弹簧恢复力由退化的Bouc-Wen模型描述；地基土中由于能量耗散和内部摩擦而产生的幅射阻尼和材料阻尼，由与水平非线性弹簧并联的粘壶表示。

The moderate self-confidence situation is the good psychological performance, it will be able to urge the university student psychology the health development, nearly will produce the inner dynamics, will cause them positively displays, the optimistic point of view in the study and the life "outstanding" the self-confidence can cause the individual university student to have, the complacent point of view arrogantly, if they will come across the setback, not the ideal means will restore, then, once will have "is outstanding" the self-confidence university student to be able to give up oneself or fills to society's disaffection.

适度自信心情况是良好的心理表现，它将会促使大学生心理的健康发展，近而产生内部动力，使他们在学习和生活上表现出积极、乐观的心态。"优秀"自信心会使个别的大学生出现骄傲、自满的心态，如果他们遇到挫折，没有理想的办法来恢复，那么，曾拥有"优秀"自信心的大学生将会放弃自己或充满对社会的不满。

As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.

本文通过对时空对象变化过程的分析，指出对象进化的结果不仅是特征的变化，还包括机制的变化，其直接动力是对象行为，其根本原因是其内在机制，时空事件起着对象间信息通道的作用，据此提出对象进化模型，该模型可作为多尺度时空数据集成的结构性基础，在反映时空现象的演变过程，特别是异构演变过程，以及在这个过程中产生的因果关系的同时，还可以保留时空数据的不同时间尺度和空间尺度特点，从而达到增加时空数据库的信息量的目的。

In this s cheme, when model integration proceeds to the period of analogue updating, multiple reference states are reselected and optimal forecast vectors are est i mated from multiforecasts produced by the analoguedynamical model using the hy perplane approximation method. Such a "selectionestimation" procedure is peri od ically repeated until the entire forecast is completed.

这一方法通过引入相似更新周期的新概念，在预报进行到相似更新周期时重新选取多个参考态，并采用超平面近似法将相似动力模式产生的多个预报估计成最佳预报向量，这样的&选取-估计&过程循环往复，从而完成整个时段的预报。

In this paper the forming process in the multi-ram forging process of high-pressure tee joint used in power industry and petroleum chemistry industry is introduced.

介绍了采用多向模锻锻制动力工业和石化工业用高压三通的工艺过程，通过FEM模拟总结出高压三通的基本成形规律，并揭示了高压三通多向模锻过程中水平冲头向上翘曲现象及其产生原因，为类似锻件的多向模锻工艺的设计提供了有益的借鉴。

I'd like to especially thank you for making up a song for me and you should know that every time I heard you singing it, it was like an extra injection of strength and motivation, even helping me to overcome pain occasionally during a game.

我尤其要感谢你们为我单独创作了一首歌曲，你们应该知道，每当我听到你们唱这首歌的时候，便会激起我的斗志，给了我更多的动力，有时候，甚至会使我忘掉因受伤产生的疼痛。

But because of its big slenderness ratio, smaller rigidity and damping, it is easy to cause a larger vibration in the windload and iceload function and so on, mast structure destruction accidents frequently occurred, has caused engineering and academic circles\\\s concern, this article summarizes the main structure damage diagnosis methods, carrys on preliminary dynamic analysis and the time-frequency distribution analysis with the vibration signal to the mast structure, and proposes the signal processing method is a appropriate method on the diagnosis to the mast damage.

但是，由于桅杆结构长细比很大，刚度、阻尼较小，在风荷载、裹冰荷载等作用下容易产生较大幅度的振动，桅杆结构的破坏事故时有发生，引起了工程界和学术界的重视，本文总结了几种主要的结构损伤诊断方法，并对桅杆结构进行了动力分析和振动信号时频分析，并提出信号处理的时频方法对桅杆损伤进行诊断比较合适的。

The images produced by computer simulations of the galaxy model show unanticipated features and have been the impetus of r further studies by astrophysicists and astronomers.

所产生的图像的计算机模拟显示银河系模型预料的特点，并已研究开发的动力进一步研究的天体物理学家和天文学家。

11 A second proof for the main conclusion is this. The end is the first cause in causing, wherefore Avicenna calls it the cause of causes. Reason confirms this, for the end moves metaphorically in so far as it is loved, and this is why the efficient cause gives form to the matter.

2.11 对主结论的第二个证明如下：目的是产生因果关系的第一因，因此阿维森纳称之为诸因之因，我们的理性证实了这一点，因为目的只要被仰慕，它就以隐喻的方式运动，这就是动力因把形式赋于物质的原因。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
