三维

Compared with the common definition in the three-dimension method, the radiation intensity I〓 after dimensionality reduction is defined on the base of plane angle.

与三维方法不同的是，降维后的辐射强度I〓是在二维系统平面角的概念上导得的，其值为辐射力E的一半，即I〓=E/2。

This is interpreted to be the result of cooperative influence of grain—shape, equiaxiallization process, texture and deformation mechanism transition. A propose is made for Coble crecp dominated deformation that three dimensional rather than two—dimensional microstructure should be considered.

在研究了Coble扩散机制变形时的三维本构关系的基础上指出，材料在二维面内的超塑性各向异性变形，有可能取决于其三维晶粒尺寸。

Besides merits of the two dimensional generation of random aggregate model, It consider the effect of the radius of the different aggregates, which were assumed to obey normal distribution. Consequently, the numerical model generated is reasonable.5. The 3-D random model of convex polyhedron aggregate was generated with 3D-RAS.

三维混凝土随机骨料投放算法是二维投放算法的延伸，除了具有二维算法的一切优点外，还考虑了骨料粒径的变化，假定骨料粒径服从正态分布，从而使该软件生成的随机骨料模型和实际结构更为接近。5。

Through customizing 3D template and 2D drawing template, Improving the efficiency of using Pro/Engineer modeling greatly, bringing the result that gets twice the result with half the effort to the establishment of the 2D drawing and BOM too.

通过三维模板及二维工程图的定制，大大提高了使用Pro/Engineer建模的效率，也给二维工程图及BOM的创建带来事半功倍的效果。

Considering the popularity of plane problems, the expressio n of the elastic constant of three-dimensional piezoelectric materials under tw o-dimensional condition were also derived, which made preparations for the two -dimensional theoretic analysis.

考虑到平面问题的广泛性，推导得到了三维压电材料的弹性常数在二维情况下的表达式，为二维理论分析作出了准备。

Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.

在这一研究内容下，主要研究四个方面的问题：(1)在完成金属波导传输线方程时域形式的基础之上，应用有限积分技术，把波导特征模式的色散传输线方程，化简为一组新的一阶偏微分方程组，该边值问题属一维Dirichlet边值问题，从而便于用蛙跳格式求解，由于是在一维中计算，该方法具有很高计算效率和精度，从而避免了以往为得到金属波导中特征模的时域响应特性，须要求解二阶方程，或用时域有限差分方法求解三维问题的方法，对于后者来说，计算有时是不准确的，或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。

If our ant on the newspaper were a two-dimensional Flatlander, then folding his two-dimensional world through the third dimension would allow him to magically disappear from one location and appear in a different one.

如果我们的报纸上的蚂蚁也是个二维Flatlander，那将这个二维世界折成三维后将让这个蚂蚁神奇的从一个位置消失去到另一个位置去。

I was a university student, I had not done a very complex programming exercise, This is the first time I upload source. this is the upload computer graphics, I do exercises at the WIN-TC environment prepared by some of the procedures, these are the basic 2D graphics transform (translation, rotation, Shear, Zooming, symmetric) animation demonstration, three-dimensional map of the two-dimensional plane of the hidden map, the lines cut, the parabolic mapping and B-spline curves mapping, detailed procedures of the Notes, and I hope to the students friends to help.

详细说明：我是一名大学的学生，我没有做过很复杂的编程练习，这也是我第一次上传源程序，这次上传的是我做计算机图形学的练习时在WIN-TC环境下所编的一些程序，其中有二维图形的基本变换（平移，旋转，错切，放缩，对称）的动画演示、三维图在二维平面上的消隐图的显示、线条的裁减、抛物线的绘制以及B样条曲线的绘制，程序中有详细的注释，希望对学生朋友们能够有所帮助。

Factually, what Gombrich was interested in is to describe how a painter turns a 3D object to a 2D painting with the 3D illusion by means of his or her eyes, with the support from various theories of modern psychology, sociology and philosophy (e.g., the visual prevision theory of Gibson, falsificationism of Popper, iconology of Erwin Panofsky, etc.), after the research on a great number of works, artists and related classics and literature.

其实，贡布里希的兴趣是在各种现代心理学、社会学与哲学的支持下(吉布森的视觉预知理论、波普尔的证伪主义、潘诺夫斯基的图像学等等)，通过对大量作品、艺术家与相关的经典和文献的研究来仔细描述人是如何用自己的眼睛这个器官，把一件处在三维当中的物体转变成二维上的平面绘画的，而这平面上的二维又具有三维空间的错觉感。
