| 1 | Study on Fungi Belonging to Fusarium Link in Ningxia Hui Autonomous Region显示文摘[Objective]This paper was to identify fungi belonging to Fusarium Link. [Method] The fungal species, distribution and the diseases caused by Fusarium Link in Ningxia Hui Autonomous Region were determined by the methods of field investigation, collection, isolated culture and identification.[Result]Nine species of fungi belonging to Fusarium Link were identified, including F. avenaceum, F. concolor, F. culmorum, F. graminearum, F. moniliforme, F. nivale, F. oxysporum, F. solani, and one unnamed species. They were distributed throughout Ningxia Hui Autonomous Region and caused more than 30 kinds of plant diseases.[Conclusion]Fusarium Link had many species in Ningxia Hui Autonomous Region without regional features, and all of them were plant pathogens. | Ruiqing SHEN Ping ZHANG Chengjin GUO Lirong ZHANG Pingzhi KANG | 2012 | Plant Diseases and Pests2012，3，2： | 2 |
| 2 | Ultrahigh hardness of carbon steel surface realized by novel solid carburizing with rapid diffusion of carbon nanostructures显示文摘In this study, a novel rapid solid carburizing process with a large diffusion depth using nano-diamonds(NDs) was conducted for low carbon steel. Changes of annealed NDs were obtained by Raman spectroscopy and transmission electron microscopy(TEM), and the results suggested that the NDs experience a stripping process before a special solid-reaction with surface iron atoms from steel substrate. Onionlike carbon(OLC) derived from the annealed NDs provided broken graphitic ribbons as carbon sources that accelerated the rate of adsorption and diffusion. Examination of the surface layer at equilibrium using TEM and X-ray photoelectron spectroscopy(XPS) also revealed the special state of carbon, and an ultrafine mixed phase microstructure was obtained by rapid solid-phase transformation. As a result, a surface hardened layer with ultrahigh hardness and a smooth transition region were realized. We believe that these kinds of diamond or graphitic structures with high activity states have an important influence not only on adsorption and diffusion but also on this special solid-phase transformation. | Qing Tao Jian Wang Liming Fu Zheng Chen Chengjin Shen Dekun Zhang Zhi Sun | 2017 | Journal of Materials Science & Technology2017，33，10： | 0 |
