平面

Analyses of loci in the π plane and meridian line s show that the parabolic and hyperbolic type failure envelopes have no influences on the shape of the.

对改进式所作的π平面极限线和子午线分析表明，采用抛物线和双曲线形强度包络线基本上不会改变原准则在π平面上的极限线形状，但子午线由直线改为曲线，极限面在主应力空间内分别为抛物面和双曲面，其锥顶距坐标原点也比采用线性强度包络线的要小。

And the use of linear time-structure optimal hyperplane method of implementation in the feature space for solving the optimal hyperplane.

然后利用线性可分时构造最优超平面的方法，在特征空间中实现最优超平面的求解。

First,a formula to calculate the normal vector of any hyperplane is given and a mixing matrix recovery algorithm based on the normal vector of any hyperplane is proposed.

首先给出了m维超平面的法矢量的计算公式，提出了一个基于超平面法矢量的矩阵恢复算法。

Since traditional product design commonly signifies mechanical parts and their assembly relations by ichnography and shows machine at a settled position.

传统的产品设计通常采用平面图形表示机械零件及其装配关系，设计的结果是机器在某一位置的静态平面图形。

With this aided system ,we can get the general function of an ichnography edit system,and also get the 3D graphic for the construction site.

利用该系统可以快速地进行施工总平面布置设计，具有一般平面编辑系统所要求的各项辅助功能，同时可以对任意工期内施工现场的实际布置情况进行三维表达或以动画方式模拟实际建筑设施随工期的推进而发生的变化。

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。

By spectral analysis of the system, we find that 0 is the uniquespectral point of system on the imaginary axis.

同时通过研究系统算子的谱特征，证明了系统算子的谱点均位于复平面的左半平面且虚轴上除0外无谱，进而得到系统的渐近稳定性，特别在范数意义下系统的动态解收敛到稳态解。

The rendered image you create with Blender is a projection of the scene onto an imaginary surface called the viewing plane . The viewing plane is analogous to the film in a traditional camera, or the rods and cones in the human eye, except that it receives simulated light, not real light.

你用Blender创建的渲染好的图片其实是对场景的一个在投影平面上的投影，除了它接受虚拟的而不是真实的灯光，投影平面类似一个传统的照相机中的胶卷，或者类似人眼中的视网膜。

Intersection as a node of road network that traffic disorder, and the frequent traffic accidents. Therefore, through designing the plane intersections to improve the safety of the intersection, increasing the capacity of plane intersection is the importable step of resolve urban traffic congestion problems.

交叉口作为城市路网的节点，交通秩序混乱，交通事故频发，因此，通过交叉口交通设计来改善平面交叉路口的交通安全状况，提高平面交叉路口的通行能力是综合解决城市交通拥挤问题重要的一步。

Using the method of mirror image, this paper discusses the distribution of the electric field in the space and the induced charge in the plane of the conductor when there is a point charge and a finite long line of charge near an infinite plane of the conductor.

利用镜象法讨论了在无限大导体平面附近有点电荷及一段线电荷时，空间的电场分布以及导体平面上感应电荷的分布。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
