According to if there exists a one to one mapping between the two point sets to be matched, PPM can be divided into the case of complete matching and the case of incomplete matching. According to transformation type between the two point sets, PPM can be divided into the affine (including Euclidean and similarity) case and the projective case.

点模式匹配问题，根据待匹配的两个点模式是否存在一一对应的匹配关系，可分为完全匹配情形和不完全匹配情形；根据两个点模式之间满足的几何变换关系，可分为仿射变换（包括相似变换和欧氏变换）情形和射影变换情形。

This paper extends the solution methods for 2-D projective transformation matrix from 4 points corresponding to variety combinations of points and lines corresponding, such as 4 points, 4 lines, 1 point and 3 lines, 3 lines and 1 point, and 2 points and 2 lines, etc.

According to DTA and the microstructure information, it is obtained that the phase transformation begins from 430.1℃,the solidus point of the alloy is 614.4℃, and the liquidus point is 636.4℃.

通过对AZ31镁合金DTA曲线的分析和不同温度下金相组织的比较、分析，确定了该合金的相变起始温度为430.1℃，共晶温度为438.5℃，固相线温度为614.4℃，液相线温度为636.4℃。

The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

However, if the trigonal control point and datum transformation model do not exist, the result of base station single point absolute location can be used as reference coordinate, the measured result of which can be geo_referenced to remote sensing image using some tiepoints on the basis of the first result above.

例如 ，在利用遥感影像分类时，需要在外业获取用于监督分类的训练样地或是分类结果精度检验样地的大地坐标信息；在进行稀有树种区域分布特征调查时，希望能在遥感影像上标识出每个树的具体位置；发现某河段发生污染时，很可能需要将它的精确位置以线或面的形式显示在其它矢量或栅格图层上。
