| 摘 要： | 指出目前磁性目标探测中常规欧拉方法存在的局限性,提出在欧拉窗口内视地磁场和其他目标干扰异常联合影响为线性变化,将构造指数作为动态变化参数代入欧拉方程一并求解,并利用多元线性回归方法解决了欧拉方程非线性问题.在质量控制方案中,根据构造指数和目标深度变化规律,给出离散欧拉解滤波措施；采用层次聚类分析方法对滤波后欧拉解进行分...

| Abstract: | Considering the deficiency of conventional Euler approach in magnetic detection at present,the combining influence of geomagnetism and adjacent bodies' anomaly was assumed as linear variation.The non-linear problem of Euler equation had been figured out utilizing multivariate linear regression with unprescribed structural index.In quality control scheme,filtering technique of Euler solutions was presented based on the relationship between structural index and object depth.Adopting hierarchical clustering me... |
