Investigation of Microstructure, Mechanical Properties and Irradiation Behaviors of Nuclear Application Steels [PDF]
, 2015 在核能领域应用的关键材料的服役条件非常苛刻，需要在辐照、高温、腐蚀、受应力、热循环等极端条件下长期稳定工作，并按照可预期的方式老化、失效。堆内构件的性能与特性决定了核能可以达到的安全水平。中国从美国西屋公司引进、吸收与消化AP1000核电技术，以形成具有自主知识产权的核电技术，并在此过程中着重对一系列核能关键用材料进行了相关研发。本论文以国产SA-182F304钢、304SS钢、CNST1钢、CNST2钢和CNSS3钢为研究对象，对候选钢的微观结构、微观化学、力学行为和抗辐照性能进行了详细研究 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT This study introduces a novel velocity‐iterative directional annealing (IDA) strategy to overcome stagnation challenges in columnar grain growth of Ti‐48Al‐2Cr‐2Nb alloys. By dynamically adjusting hot zone migration rates across iterative cycles, the IDA protocol achieved 92.2% synchronization between anisotropic α‐grain boundary (GB ...

Implications of the Pragmatic Presentation in English Learner’s Dictionaries to the Revision of The Contemporary Chinese Dictionary ( Chinese English Edition 2002) [PDF]
, 2016 语用学作为语言学的后起之秀，对英语学习词典的编纂起到了重要作用。最近几十年，语用学在中国得到了快速发展，许多词典编纂研究者积极探讨语用学理论对词典编纂的应用。遗憾的是，语用学的研究存在理论引进和实践脱节的现象。2002年，《现代汉语词典》双解版问世，为汉语在全世界进一步推广起到了重要作用。十几年过去，随着孔子学院在全世界范围扎根，对外汉语开展得如火如荼，《现代汉语词典》双解版原有的语用信息量和呈现方式却远远无法满足时下汉语非母语学习者的需求。为丰富《现代汉语词典》双解版中的语用信息的内容和呈现方式 ...
