| 摘 要： | 研究表明海洋贝壳表面形貌与防污性能存在一定的关系。为评定贝壳表面形貌,探讨贝壳表面形貌与其防污性能关系,采用接触式表面轮廓测量仪对贝壳的表面形貌进行测量;运用二维双正交小波变换消除贝壳表面形貌测量数据中的形状误差,计算常用的表面特征参数。结果表明:运用二维双正交小波变换将贝壳表面形貌测量数据中的形状误差消除后,可得到更加合理的表面特征参数评定结果,可用于贝壳表面形貌的评定。

| Abstract: | Some researches indicated that there is a certain relation between topography and antifouling properties of shell surface.In order to evaluate shell surface topography and discuss the relationship between surface topography and antifouling property of shell,shell surface topography was tested using contact measuring profilometer and after shape error being removed by two-dimensional biorthogonal wavelet transform,common characteristic parameters were calculated.The results show that more reasonable evaluati... |
