A novel method to prepare Au nanorings by self-reduction of HAuCl4 in the soft template composed of sodium dodecyl sulfate-PEG 20000 cluster at ambient temperature and atmosphere was reported, in which no hard template and extra reducer was needed. TEM image displays that the diameter of Au nanorings is (500±50)nm.

介绍一种由十二烷基硫酸钠与聚乙二醇(PEG 20000)组成的团簇为软模板，在室温、常压、无硬模板及无外加还原剂条件下自还原HAuCl4合成金纳米环的新方法。

When detecting the edge, an auto-choose threshold algorithm is given to reduce the salt-and-pepper or pulse wrong edges. After analyzing the special noise factor in pin's image, this paper improves the edge detection elements. That's putting forward a way which is named"the method of de-noise based on linear weighted operator template"to reduce the zonal or cluster noise. And test show that the algorithms detect image's edge rightly.

针对钻针图像的特点，在边缘检测中提出了自动选择阈值的算法；之后针对钻针图像中的特殊噪声形式，对边缘检测算法进行了原理上的改进，通过对图像的灰度分布的数学模型的建立，提出了使用加权直线模板去噪法进行块状噪声的去除；通过上述算法的应用，良好地改善了图像处理的质量。
