Using the information obtained from the study of these normal variations of vertices near a sharp edge or a high curvature area of the target space to detect features.The watermarks embedded by using the method can be detected,to some extent,after such attacks as cropping, simplification,similarity transformation,and additive random noise applied on the watermarked point set model.

最后对已加水印的点集模型应用不同的攻击，比如剪切、简化和附加随在特征点附近嵌入水印信息机噪声之后，结果显示通过这种方案嵌入的水印，在某种程度上仍可以被检测到。

For the capacity of propeller turbine is often small, people pay little importance on the transformation of reducing capacity under specified conditions. So, nowadays little research mentioned above has been developed.For the particularity of the designed factors, the author has improved the traditional theory, and has fined an available Method of singular point distribution.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
