摘要
本文对现有平方变换方法进行了研究,提出了平面场不同平方变换的不同几何实质.这不仅有利于理解方法本身,更重要的是提供了一种有目的地建立新的平方变换的方法.
In this paper, the geometric essence of quadratic transformation in plane field is presented after studying the existing quadratic Troms formations. This is not only useful for understanding the method itself, but also helpful for further producing another nen method.
