用带自适应运动极限的序列线性规划法，对具有不同模量悬式绝缘子的瓷头部分进行形状优化。其中的结构分析采用不同拉、压模量空间轴对称问题的有限元法。讨论了材料不同模量性对优化结果的影响，为悬式绝缘子形状优化设计提供了较为有效的方法。     

低气压条件下绝缘子污闪特性的研究

污秽绝缘子的闪络电压Ｕ和大气压力户之间的关系为Ｕ＝Ｕ。（Ｐ／ｐ０）ｎ，Ｕ０是该污秽绝缘子在标准大气压户。下的闪络电压。作者用固体污层人工污秽试验方法研究了不同形状绝缘子在不同污秽度下以及在不同大气压力下的污闪电压，并研究了在交流和直流电压分别作用下的污闪电压差别。试验结果表明，上述公式中的指数ｎ在交流电压下的数值大于直流电压。对于形状简单的绝缘子ｎ值不受污秽程度影响，对于形状复杂的绝缘子ｎ值受污秽程度的影响。ｎ值变化的原因在于绝缘子伞裙间的电弧桥络现象。

运用中子活化分析(NAA)技术,测定耀州瓷釉中29种元素的质量含量,从中选取24种着色元素．通过对比分析,最后确定铁是耀州瓷的着色主元素,证明了考古界“耀州瓷以铁为着色主元素”的说法．     

Fuzzy cluster analysis of the provenance of ancient Yaozhou porcelain body

The technique of neutron activation analysis (NAA) has been employed to measure the content of 29 kinds of elements in the sample of Yaozhou porcelain bodies,Then a fuzzy cluster analsis has been conducted to the NAA data and a diagram of the dynamic fuzzy cluster analysis has been achived,The results indicate that the batch of ancient Yaozhou porcelain bodies,which were of different overglaze color and were produced by different kilns during a period of over 800 years from the Tang Dynasty (618-907 A.D.) to the Yuan Dyansty(1271-1368 A.D.) ,has shared a stable and concentrated raw material source,Provenances of porcelain bodies from different times ,though having their specific independence ,enjoy a close relationship and are not far from one another,Provenances of porcelain bodies made during the Tang Dynasty and the Five Dynasties (907-960 A.D.)are found to be closer to one another,while those of the Song (960-1279A.D.) and the Jin Dynasty (1115-1234 A.D.)are comparatively concentrated in certain areas and are different from those of the Tang Dynasty .Both the tri-colored glazed pottery made in Yaozhou kilns during the Tang Dynasty and the Yaozhou porcelain bodies of the Tang period are from the same provenance.

Neutron activation analysis and M(o)ssbauer spectroscopy research on coloring mechanism of ancient Chinese Guan porcelain

The content of 30 kinds of coloring elements in Guan porcelain in the Southern Song Dynasty has been determined by neutron activation analysis (NAA). Iron is the major coloring element. M(o)ssbauer spectroscopy has shown that the iron of the glaze exists in the form of structural iron (Fe2+, Fe3+). The quantitative relationship between the main wavelength of every color glaze and the relative content (Fe2+/Fe3+) of structural iron has been determined. Thus the coloring mechanism of Guan porcelain in the Southern Song Dynasty has been revealed entirely.     

基于红外图像的绝缘子串自动提取和状态识别

为解决目前绝缘子低零值检测方法漏判率高、操作繁琐的问题,提出了一种新的绝缘子串红外图像中绝缘子盘面和铁帽区域自动提取方法和状态识别模型.首先将现场拍摄的绝缘子红外图像进行灰度化处理、去噪、二值化;然后从二值图像中提取反映绝缘子的特征点集合;通过特征点对二值图进行角度校正;最后通过区域提取中的特定算法提取出绝缘子的盘面和铁帽区域.通过提取该区域内的绝对温度、纹理和相对温差率作为绝缘子状态识别的特征集.将用电压分布法测得的绝缘子状态信息作为输出向量,通过训练得到优化的识别模型,用于绝缘子状态识别.该方法经过了220kV试验验证,证实了模型的有效性和实用性.
