不变形的

Thismethod adopted affine transformation model and a Lie derivative-based analytical algorithm.We introduced the process and characters in extracting information of biological visionsystem, studied the feasibility of the generalized Gabor function used as receptive fieldfunction in extracting information and analyzed affine transformation group and Liederivatives. Finally, we deduced the mathematical denotation for Lie derivatives, i.e. theinfinitesimal generator of the geometric distortion in affine transformation.

对生物视觉信息提取的过程及特点进行了介绍，其中主要研究了广义Gabor函数作为感受野函数提取初级视觉信息的可行性；对仿射变换作为外界图像信息在视觉成像系统上的投影模型的原理进行了初步讨论；对Lie变换群微分算子用于提取仿射变换不变量的分析方法作了剖析，并推导了该方法中关键部分——仿射变换Lie微分算子的具体表达式，也就是几何变形无限小微分算子的计算表达式，使下一步编程实现该方法成为可能。

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

The thylakoid of chloroplast was lost, the chloroplast was shrinked and composed into several discontinuous parts, which suggest that the function of chloroplast was destroyed;(2) the cell wall was thickened clearly, plasmolysis was found in most of Platymanas subcordiformis cells;(3) the number of mitochondria increased, some cristae of mitochondria were dissolved;(4) the number of vacuolar increased and the size of vacuolar was not uniform, the shape was deformed;(5) the nucleus was deformed and part of the nucleus membrane was dissolved;(6) Golgi dicytosomes accompanied with a loose arrangement of cisternae and the peripheral tips of the dictyosome cisternae are not especially swollen.

叶绿体内的类囊体缺失，叶绿体皱缩，叶绿体被分离成几个不连续的部分，说明叶绿体功能被破坏；(2)细胞壁明显增厚，细胞壁与细胞膜存在质壁分离现象；(3)线粒体数目增多，部分内嵴遭破坏；(4)液泡数目增多，大小不等，形状不规则；(5)细胞核变形，核膜部分解体；(6)UV-B处理的高尔基体有一个排列松弛的潴泡，潴泡的外围顶端并没有特别膨大。

Practice proved that setting the late moulding could efficiently solve the problems including constructing the large ferroconcrete moulding, the over long architectures and the different-height-joined ones, the equilibrium of the sedimentation and distortion resulting from the different height and density.

实践证明，通过设置施工后浇带，既可以解决大体积混凝土浇筑、超长建筑和高低相连建筑的中的施工问题，同时又可以解决高低或刚度极不均匀的两部分结构沉降变形的协调问题，从而有效的解决了这一矛盾。

A modified backward Euler method is developed which enables to increase considerably the accuracy of jump voltage computation as a result of freeing its computing from the influence of the faint asymmetrical initial current in such an inductive circuit as converter and completely eliminate numerical oscillation in converter simulation as often seen in the case of implicit trapezoidal integration method.

本文提出一种变形的后退欧拉法，用该法对换流器这样的纯电感电路进行跃变电压计算，可完全避免初始电流中微弱的不平衡对跃变电压计算的影响，大大提高了跃变电压的计算精度，并彻底消除了隐式梯形积公法用于换流器仿真时所存在的非原型数值振荡。

Furthermore, guaranteeing the participance of the parties and the public, strengthening the dependency of the parties of the jurisdiction, and securing the realization of the principle of publicity, by the way of substantiation the process of trial. As a fundamental principle in trial, the principle of concentration definitely influences the hearing structure and the instance structure greatly, while substantiating the process of trial.

作为一项基本的审理原则，集中审理原则在充实庭审程序的同时，必然在审理结构和审级结构上发挥着巨大的作用：从横向上看，集中审理原则使一个充实的、独立的审前准备程序成为必要，以此维持"准备程序+集中审理"这一两阶段审理结构不至于变形；从纵向上看，集中审理原则要求当事人适时提出攻击防御方法，限制当事人在二审提出新的诉讼资料，以此充实第一审程序，减少不必要的上诉，保证整个审级结构不至于头重脚轻失去平衡。

In this thesis, we propose a new semi-automatic system that is able to create interesting 3D effects from plain photographs. By directly projecting the ground plane without the use of camera parameters, we avoid the problem of creating images with wrong depth ratio and texture distortion.

本论文修改了还原真实场景比例的立体化方式，将影像中属於地面的部份，以原始大小直接投影至立体空间，这麼做出现了类似立体书或立体卡片的效果，同时也省去了设定相机参数的步骤，避免因不正确的参数设定导致错误的深度比例或材质贴图的扭曲变形。

It is just reducible or non-fundamental, in the same way that consciousness emerges from brain activity but is not illusory.

尽管时间的观念是可变形的或者是非基本的。然而来自人的头脑活动的意识总不能仅仅是幻觉吧。

Simulation result of the experiment shows that unloading and recovery process of PTCS is not consistent with the local stress redistribution and concentration.It can be divided into four phases:1.local stress unloads first in the middle of PTCS;2. stress continues to unload near the incident bar.3.Stress continues to unload near the transmission bar,the first and second layer PT buckling rumple disappear;4.the whole PTCS vibrates elastically.

对具体冲击实验的数值模拟结果表明：相变柱壳的卸载恢复过程在柱壳结构中是不均匀的，伴随着壳体局部应力释放和局部应力集中，可以分为以下四个阶段：1、柱壳中部发生弯曲变形的壳体应力首先释放，2、靠近入射杆端的壳体应力继续释放，3、靠近透射杆端的壳体应力释放，第一层与第二层相变屈曲皱褶消失，4、柱壳整体弹性振动。

The exact solution for unlimited long strip plane membrane is obtained by analytical method,and discussed with the approximate solution by energy method.

在垂直于板的载荷作用下，平衡方程为σx2wx2+σy2wy2+2τ2wxy=qh[2]。这个方程虽然是在变形后建立的，但载荷的大小和方向是不变的。

I can still vividly recall the impressive scenes you gave. You were among my friends and relatives who accompanied me from my house to the seaport and when the porters were slow to show up, you obligingly carried my suitcase for me.

你对我的种种感人情意，使我记忆犹新，那天你随着我的亲友从家里送我上轮船，搬运工迟迟不来，你毅然替我提着皮箱上船。

St. Nicholas became the patron saint of Russia, where he was famous for his red cape, flowing white beard, and bishop's mitre.

圣尼古拉成了俄罗斯人的守护神，在那里，他以身披红斗篷，留着飘逸的白胡须，戴着主教法冠而闻名。
