one-one mapping

This tree can map the net points of space onto a set of integers with one-one mapping based on the coordinate net binary tree,so can map any point of the space to a integer with arbitrary accuracy also.

利用该坐标网，把空间中的网格点一一映射到一个整数集合上，从而可以把空间中的任意点近似地映射为一个整数，而且可以任意精确。

For the mapping algorithm it is points out that there is a"one-one mapping ring";and for the reduetive algorithm it researches two different algorithm to fit various instance.

对于映射算法,指出非均匀映射变换的距离轴离散化与角度轴离散化具有统一的"一一映射环";对于还原算法,提出了基于子像素的最优像素构造算法和简单反向算法两种不同的算法,以适应不同环境下的要求。
