A sphere cannot be represented on a flat plane without distortion, which means all map projections distort in one way or another.

球体在平面上不进行扭曲就无法表现出来，这意味着所有制图方式都会以某种方式出现扭曲。

The energy minimization characteristic of the harmonic map preserves the low distortion that may yield in the process of texture mapping.

由于调和映射具有保持映射能量最小的性质，该方法可以最小化约束纹理映射可能导致的扭曲形变。

Because the traditional SOFM often produce result with color distortion, it setting the map size with different length according to the complexity of images.

针对传统s OF M易产生色彩的映射畸变，根据彩色图像自身不同的复杂度自动选择不等边距的映射网络。
