Although the EPRI give a set of the approximate engineering solution method, actually the crack of parts in engineering project mostly presents inner 3D effect. If using 2D elastic-plastic or 3D elastic analysis, the result can't be precise. Because these methods have neglected the reassignation of the stress and strain which happened at nearly the top of cracks, carrying on 3D elastic-plastic analysis and J-integral calculation become the foundational work to study the expander and safety assessment of the pressure vessel cracks.

虽然EPRI给出了一套近似的工程解法，但实际上工程中构件的裂纹大多呈现内在的三维效应，若使用二维弹塑性或三维弹性分析必然不够精确，因为对裂纹的&等效&二维表达忽视了发生在靠近裂纹端部的应力和应变的再分配，所以对压力容器裂纹进行三维弹塑性分析及其J积分是研究压力容器裂纹扩展和安全评定的基础工作之一。

This paper presents a Double Kohonen Neural Network lased on the Self－Organize Feature Mapping theory to analyge chomosome automatiolly. The DKNN consists of two layers, each of which is a Kohonen network. The first layer maps a 2－d plane to a 2－d feature space to extract the high－resolution bands of chromosome and to compute the parameters of bands. The second layer maps the arrays of high dimension feature parameters to a 2－d plane to pair and classify the chromosomes automatically.

The previous work on the SKAWs was extended from the one-dimensional case to the two-dimensional case, and it was showed that the two-dimensional SKAWs with the dipole vortex structure have some important unique properties that the one-dimensional model of the SKAWs can not expect.

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD.
