They think like clerks, talk like clerks, and they approach computer programming and systems analysis with all the enthusiasm of a sleepy civil service clerk who knows that hes just one year away from retirement.having met some twenty-five thousand analysts, designers, and programmers throughout the world, i found a surprising number of them have never read any computer articles or even opened a copy of datamation or computerworld; have never heard of acm, dpma, ieee, asm, or any other professional organizations; cant spell dijkstras name and probably have never heard of him; arent aware of the structured techniques and wouldnt be interested if somebody showed them.

他们象文职人员一样思考、交谈，他们与所有积极的，但昏昏欲睡的知道自己还有一年就退休的文职服务人员一起处理计算机编程和系统分析。已经遇到过整个世界的25000个分析员、设计员及程序，我很吃惊的发现他们中的很多从来没有读过任何计算机的文章甚至是公开的datamation或 computerworld的拷贝；没有听说过acm，dpma，ieee，asm，或者是其它任何专业组织；不能拼出dijkstra的名字，可能从来没有听说过他；不清楚结构化技术，即使是有人告诉他们也不感兴趣。

The paper gives stiffness matrix and mass matrix in finite element analysis of the ground vibration problem caused by track traffic by using three-dimension finite element method. Because three-dimension finite element analysis is very difficult, it is transmitted into a quadratic programming, which can be calculated by neural network.

I was the original "Wild Lily has spring" feeling Tai Su, and not directly to my central idea of the table, so then I changed to "Sex and the blessing", whose main purpose is to analyze men and women of the "happiness "In fact is not the same.

原本我是的是《野百合也有春天》感觉太俗了，不能直接表到我的中心思想，所以后来我改为《性与幸》，其主要的目的就是想分析一下男人和女人的&幸福&其实是不一样的。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。

By applying the sinusoidal wave mode to simulate the rugged surface of bridge deck,accounting for vehicle-bridge interaction and using Euler-Bernoulli beam theory, a coupling vibration model of vehicle-bridge system was developed. The model was solved by mode analyzing method and Runge-Kutta method, and the dynamic response and the resonance curve of the bridge were obtained. It is found that there are two resonance regions, one represents the main resonance while the other the minor resonance, in the reson...
