摘    要：揭示了传统的三角多项式图的本质是一种随机过程,给出了另外2种新的三角多项式图,即新形式的三角多项式图和等欧氏距离的三角多项式图.通过证明,这2种新的三角多项式图都具有传统三角多项式图所不可替代的优良性质,由此拓宽了三角多项式图的应用范围.

Abstract: Trigonometric polynomial graph is a typical kind of method of multivariate diagrammatic presentation. This paper reveals that the essentiality of traditional trigonometric polynomial graph is a random process firstly, and then give another two new trigonometric polynomial graphs,i.e. new trigonometric polynomial graph and equidistanttrigonometric polynomial graph. They both have good property that cannot be replaced by traditional trigonometric polynomial graph. Therefore, the application field has been widened.
