| 1 | 应用增爬群改善大雨条件下800 kV叠锥型支柱绝缘子的雨闪性能(英文)显示文摘Studies based on AC high voltage tests have been done at Cepel to investigate the performance of 800 kV busbar insulators under heavy wetting conditions.Insulators were tested which are now used on site and also with different configurations of booster sheds.Images recorded by ultra-violet(UV) camera were used to help the investigations on the effectiveness of booster sheds.By comparing UV images of the insulator being stressed with high voltage under heavy artificial rain,with and without booster sheds,it was possible to observe how significant the reduction on the flashover formation process was when booster sheds were used.The effectiveness of booster sheds was also quantified by determining the disruptive discharge of the insulator with and without them.The results of these studies can also be considered as contribution to national and international standard technical committees to improving the standardized procedure for tests on ultra high voltage(UHV) insulators under heavy rain.Subjects such as the clear definition of relevant UHV test procedure and test arrangements,including the use of UV camera,have to be taken into account. | Orsino Oliveira Filho José Antonio Cardoso Darcy Ramalho de Mello Rogério Magalhes de Azevedo Sylvia G Carvalho | 2011 | 高电压技术2011，37，11： | 5 |
| 2 | Magnetic resonance imaging of the cirrhotic liver: An update显示文摘Noninvasive imaging has become the standard for hepatocellular carcinoma(HCC) diagnosis in cirrhotic livers. In this review paper, we go over the basics of MR imaging in cirrhotic livers and describe the imaging appearance of a spectrum of hepatic nodules marking the progression from regenerative nodules to low- and high-grade dysplastic nodules, and ultimately to HCCs. We detail and illustrate the typical imaging appearancesof different types of HCC including focal, multifocal, massive, diffuse/infiltrative, and intra-hepatic metastases; with emphasis on the diagnostic value of MR in imaging these lesions. We also shed some light on liver imaging reporting and data system, and the role of different magnetic resonance imaging(MRI) contrast agents and future MRI techniques including the use of advanced MR pulse sequences and utilization of hepatocyte-specific MRI contrast agents, and how they might contribute to improving the diagnostic performance of MRI in early stage HCC diagnosis. | Agnes Watanabe Miguel Ramalho Mamdoh Al Obaidy Hye Jin Kim Fernanda G Velloni Richard C Semelka | 2015 | World Journal of Hepatology2015，7，3： | 5 |
