1) fracture image recognition
断口识别
1.
Two-lever wavelet transform is applied to metal fracture image recognition by selecting tree structure wavelet transform.
断口图像的识别是进行失效分析的一个重要组成部分,本文提出一种基于小波的断口识别方法,该方法采用树形小波对金属断口图像进行二级小波变换,剔除近似分量,对其余的各个频带输出的标准差作为断口识别的特征,并采用最小距离分类法进行分类,实验证明,此方法对细节丰富的断口的识别率很高。
2) identifying and diagnosing
识别诊断
1.
By analysis and study of various damage-inducing factors, a program of identifying and diagnosing damage is introduced in this paper which incorporates predicting and diagnosing models of 6 types of damage, and the field application.
文章通过对导致油气井储层伤害的各种伤害类型的预测模型和诊断模型的分析和研究,编制了储层伤害识别诊断软件。
4) Fault identification
断层识别

Application of spectral decomposition technique in fault identification
谱分解技术在断层识别上的应用
2.
For the literatures on fault identification in shallow stratum from multicomponent seismic exploration are hard to find, this paper studies fault identification based on the ideal of multicomponent seismic exploration and from travel time curve, wave form feature, phase feature, velocity and other aspects.
从多波勘探角度较全面地叙述浅层地震勘探中断层识别的文献不多见, 本文根据实际工作资料, 以多波勘探思想为基础, 从走时曲线、波形特征、震相特征、速度结构等多方面探讨了断层了的识别方法。
3.
It has major importance on fault identification in coal geological exploration.
基于波动方程的数值模拟能为地震波的传播机理和复杂地层的解释提供更多的佐证,运用了基于波动方程的有限差分方法,计算了煤层断层的地震响应,在煤层断层模拟上产生了预期效果,对煤田勘探工作中断层识别的研究有着很重要的意义。
