摘　　要：向量平移法是在充分了解Lorenz散点图与差值散点图的作图原理及其内在联系的基础上,派生出来的两图合参的分析方法,体现了Lorenz散点图与差值散点图的优势互补关系。向量平移法不仅适用于二维Lorenz散点图与二维差值散点图的综合分析,也适用于三维Lorenz散点图与三维差值散点图的综合分析。有向临界连通图是闭合的向量环,表明差值散点图满足向量守恒定律;正确标注有向临界连通图是向量平移的前提。疑难复杂病例的散点图分型复杂、规律性较隐蔽,利用两图合参的向量平移法能够充分揭示心电大数据的内在规律,特别是差值散点图特征点集互不重叠,能更好地实现编辑、选图等分析操作,使快速准确地分析疑难复杂动态心电图成为可能。The vector translation method is an analysis method of combining Lorenz scatter plot and difference scatter plot,which is derived from fully understanding their mapping principles and inherent relationship between the two kinds of plots.It embodies the complementary relationship between Lorenz scatter plot and difference scatter plot.The vector translation method is not only suitable for the comprehensive analysis of two-dimensional Lorenz scatter plot and two-dimensional difference scatter plot,but also for the comprehensive analysis of three-dimensional Lorenz scatter plot and three-dimensional difference scatter plot.The directed critically connected graph is a closed vector ring,which indicates that difference scatter plot satisfies the law of conservation of vectors.Correctly labeling the directed critically connected graph is a prerequisite for vector translation.The scatter plots of intractable case have complex typing and hidden regularity.The vector translation method by using a combination of two kinds of plots could fully reveal the inherent law of ECG big data,especially the characteristic point sets of difference scatter plot do not overlap with each other,which facilitates analysis operations such as editing and graph selection,and makes it possible to analyze difficult and complex ambulatory electrocardiography quickly and accurately.
