Treating with coils as aeolotropy, this paper brings forward a set of mathematical mode for computing internal stress distribution of coil in the process of coil coiling, in which some factors are taken into account, such as the transverse distribution of shape, crown and curl tension of the strip, the friction between the strip and the reel, the friction between strips, and etc. Because the reel shrinkage and the inner circle of the strip losing radial restrain and circumferential restrain can induce interlayer slipping and the change of the whole coil compactedness , the assumption concerned ——"virtual reel" in the process of coil uncoiling is put forward, which takes the form of slow action to express the uncoiling process and, therefore clearly simulates the variation course of internal stress distribution of coil in the process of coil uncoiling.

考虑到带材板凸度、卷取张力的横向分布以及带材与卷筒之间、带材与带材之间的摩擦力等因素的影响，并将钢卷按各向异性体处理，提出一套计算卷取过程中钢卷内部应力分布的数学模型；同时考虑到卸卷过程中由于卷筒的收缩，钢卷内圈失去径向和周向约束而引起层间滑移及整个钢卷紧密程度发生变化，提出钢卷卸卷过程中有关&虚拟卷筒&假设，将卸卷过程以&慢动作&的形式表示出来，清楚地模拟出卸卷过程中钢卷内部应力分布的变化历程。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise. In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection. Firstly, the median filter and improved Sobel method are used to preprocess seismic section images. Secondly, the threshold value is determined automatically based on variance to detect abnormal information. Finally, the complete cophasal axes are extracted after a post-processing.
