计算散度的三点法比较及订正新方案

Comparison among varieties of trilaterations applied to divergence calculation and relative correction scheme

计算散度的三点法有许多形式。对这些形式的联系和区别,有必要作出统一评价。经数学演绎后,得出这些方法实质上一致,方法之间或完全相等,或相差一个可忽略的微量。此外,为弥补三点法面积形状各异造成的误差,提出了订正新方案,为计算大范围散度场统一评价提供了方便。最后进行了实例验证。

In this paper! varieties of irilatorations applied to divergence calculatinn are compared. The results of mathematical deductions show that all these methods are quite identical or like, And a new correction scheme is given.
