| 1 | 材料的活性屏等离子渗氮显示文摘近年来,等离子渗氮技术的迅速发展和在表面工程领域的应用呈现出减缓的趋势,其原因是传统的直流等离子体技术存在一些固有的缺点,例如,炉温难以保持均匀,等离子体不够稳定以及因打弧而引起工件表面损伤等。克服这些不足之处的努力促使了活性屏等离子渗氮(ASPN)技术的发展。本文从技术和环境优势角度证明,ASPN可以应用于低合金钢、工具钢、不锈钢以及能进行传统直流等离子渗氮的其他钢种。此外,ASPN可以处理不适合直流等离子渗氮的非导电材料,如经氧化处理的钢和高分子材料。从长远看,对环境友好且技术先进的等离子渗氮比传统的盐浴和气体渗氮更有优势。活性屏等离子渗氮技术是充分发挥等离子体技术在化学热处理及有关表面工程中应用潜力的新方法。 | T.Bell C.X.Li 顾剑锋 | 2012 | 热处理2012，27，1： | 3 |
| 2 | Study of the Active Screen Plasma Nitriding显示文摘Active screen plasma nitriding (ASPN) is a novel nitriding process, which overcomes many of the practical problems associated with the conventional DC plasma nitriding (DCPN). Experimental results showed that the metallurgical characteristics and hardening effect of 722M24 steel nitrided by ASPN at both floating potential and anodic (zero) potential were similar to those nitrided by DCPN. XRD and high-resolution SEM analysis indicated that iron nitride particles with sizes in sub-micron scale were deposited on the specimen surface in AS plasma nitriding. These indicate that the neutral iron nitride particles, which are sputtered from the active screen and transferred through plasma to specimen surface, are considered to be the dominant nitrogen carrier in ASPN. The OES results show that NH could not be a critical species in plasma nitriding. | ZhaoCheng C.X.Li H.Dong T.Bell | 2004 | 材料热处理学报2004，25，5： | 1 |

| 5 | 在欧洲油菜品种‘Surpass400’中控制黑胫病抗性的一个单显性等位基因的鉴定显示文摘曾经报道过油菜(B.napus L.)商用品种的黑胫病抗性。黑胫病是由Leptosphaeria maculans(Desm.)Ces.&de Not.引起的。从冬油菜(B.napus)‘Major’בStellar’杂交组合中,Ferreira等人(1995)曾经鉴定出一个单主效位点(LEM1)和4个次要区域。 | C.X.Li 向平 | 2004 | 国外作物育种2004，23，4： | 0 |
