5自动测试系统应用面向对象方法的现实显示文摘有许多ATE供货商宣称他们的面向对象的软件系统提供比较高的生产能力。在一定程度上他们的声明是真实的。但是,实际的生产能力优势不仅是来自面向对象。面向对象编程技术仅仅是寻求提高生产能力的一个部分。本文论述面向对象研究的重要性及其好处,但也强调建立下一代系统所必需的其它主要特性。James R.Ward 张秀兰 1994微电子测试1994,8,4:0
6Visualization of atomic scale reaction dynamics of supported nanocatalysts during oxidation and ammonia synthesis using in-situ environmental(scanning) transmission electron microscopy显示文摘Reaction dynamics in gases at operating temperatures at the atomic level are the basis of heterogeneous gas-solid catalyst reactions and are crucial to the catalyst function.Supported noble metal nanocatalysts such as platinum are of interest in fuel cells and as diesel oxidation catalysts for pollution control,and practical ruthenium nanocatalysts are explored for ammonia synthesis.Graphite and graphitic carbons are of interest as supports for the nanocatalysts.Despite considerable literature on the catalytic processes on graphite and graphitic supports,reaction dynamics of the nanocatalysts on the supports in different reactive gas environments and operating temperatures at the single atom level are not well understood.Here we present real time in-situ observations and analyses of reaction dynamics of Pt in oxidation,and practical Ru nanocatalysts in ammonia synthesis,on graphite and related supports under controlled reaction environments using a novel in-situ environmental(scanning) transmission electron microscope with single atom resolution.By recording snapshots of the reaction dynamics,the behaviour of the catalysts is imaged.The images reveal single metal atoms,clusters of a few atoms on the graphitic supports and the support function.These all play key roles in the mobility,sintering and growth of the catalysts.The experimental findings provide new structural insights into atomic scale reaction dynamics,morphology and stability of the nanocatalysts.Michael R.Ward Robert W.Mitchell Edward D.Boyes Pratibha L.Gai 2021Journal of Energy Chemistry2021,30,6:0
7影响海产品微生物指标的因素显示文摘在诸多影响海产品微生物指标的因素中,有的与微生物的关系简单,有的则很复杂,有的是海产品本身固有的,有的则是由处理和加工过程带来的.这些因素究竞如何影响海产品的微生物指标,很难全部弄清楚.本文综述了影响海产品微生物指标的诸因素.Donn R.Ward 王建中 周晓莉 1991国外水产1991,,2:0
8用电渣重熔锭制造9Cr-1Mo钢原子能管板锻件的生产显示文摘本文叙述了用于快中子增殖反应堆的大型截面9Gr-1Mo钢管板锻件的生产和质量。把电渣重熔法应用于炼钢,除改善了化学和冶金均匀性之外,还消除了大的非金属夹杂。为得到良好的机械性能和细晶粒度,就选择化学成分和热处理状态的最佳条件进行初步的调查研究。根据初步调查研究结果制成的管板锻件,质量极好,超过了全部规范要求。M.Kohno T.Abe H.Kikuchi K.Sekimoto T.Miyawaki C.Bolton R.Ward 菁华 1986大型铸锻件1986,,2:0
