Its on the oriental stage that a series of oncoming and dormant Oedipus tragedies-incest tragedies, with which the westerners are so familiar regardless of performance on the somewhere strange stage, are highlights, so that the western spectators not only can enjoy the different exotic cultural charms, but from the commanding perspective fell the superiority of their own culture in this fabricated cultural context featured with backward, isolation and far from the reality. In addition, Zhang prefers to the method of time lagging in the film text formation, so that the textual times usually drag back to the past on purpose such as 1930s, 1940s, per-anti-Japanese war period as well as 1960s and 1970s; apart from this, the far-off areas far from the cultural center are chosen as the film space, all which get together to set up a static, stagnate and hiding Chinese traditional cultural context symbolized by backward, barbarousness and ignorantness to satisfy the male desire.

为了营造这个虚拟舞台，张艺谋影片中的采用了时间的滞后性策略，影片中的故事本文时间均选择了过去：十九世纪三十、四十年代，抗战前期，六七十年代；影片中的本文空间均选择了远离文化中心的边缘地带，通过时间的滞后策略和空间的边缘策略来满足一个停滞的、凝固的、静止的落后而由愚昧野蛮的中国传统文化语境；将处于社会边缘的女性放置在其中，利用观众位置的双重性认同结构，巧妙利用女性这一表层可见视觉中心和读解影片时意义渐隐的策略来遮掩和移位其真正的作者意识形态：即重复再一次对女性的观看，满足东西方男性的窥视欲望。

According to the boundary curve features of the object, all kinds of boundaries sign patterns of the object are setup and used to train the second RBFNN, so as to tangent points, inflection points with low curvature and boundary types.

根据工件边缘曲线的特征，建立了各种边缘的曲率符号模型，用该模型训练第二个RBFNN，从而识别具有低曲率的切点和拐点及边缘曲线的类型。

In addition, combined with Hough transform of Iris outer boundary, an improved Canny operator was designed to detect edge only in vertical direction.

其次对传统的Canny边缘检测算子进行改进，使其只在垂直方向上检测边缘，并结合Hough变换定位外边缘。

It modified some terms of the initial formula, which made the snake model not only precisely extract the edge of the protruding object in images but also approach to the concave part of the edge. It introduced exterior sanction energy, which could adaptively change its value to enlarge suction, so that control points could quickly constringe to the real contour without relying on the initial contour. Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.

通过调整原始公式的一些参数使得该模型不但能精确地提取图像中的凸形物体的边缘，而且能够接近边缘的凹陷处；引入自适应改变大小的外部约束能量来增大外能的吸引范围，使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓；结合匹配技术，提高边缘提取结果层间传递的精度。

Experiments show that the performance of the new approach to the edge classification is better than that of the traditional kind in the edge accuracy. stability and the edge smooth and continuousness, except for more edges and Less noise.

实验结果显示，基于颜色恒常的照度准不变边缘分类算法，在光照颜色变化的情况下，不仅能检测出更多的边缘，噪声点更少，而且检测的边缘更准确，稳定，线条更光滑连续。

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

这种非接触的测量方式，采用RAC两步法对摄像机进行标定，然后对采集到的钢板图像进行分析处理，通过多项式插值的方法，采用具有保持边缘特征和滤波功能，且能适应非均匀照明的十字窗图像边缘检测算子进行象素级边缘检测，再用最小二乘拟合法和逆透视法对二维图像进行三维重建，便可测出钢板上给定点的距离及其变化值，以期为水火弯板的变形机理研究提供一种新的检测手段。

In short, the innovation points of this paper can be listed as follow:This paper constructed an integrated regional leading industry selection model; Thispaper provided a game model to explain actions that happened in the competitionbetween two local governments; This paper built leading industry selection risk evaluation system based on the government competition game model; This paperpresented development path and countermark of leading industry in marginal region.

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
