Effect of Transverse Static Magnetic Field on Droplets Transient and Inclusions Evolution During the Electroslag Remelting Process of GCr15 IngotsQiang Li,Yun-Bo Zhong,Chu-Xiong Sun,Huai Wang,Tian... the influence of the static magnetic field on droplet evolution during the magnetically controlled electroslag remelting(MC-ESR) process. MC-ESR experiments were carried out under different remelting current......
; 文献标志码:A 文章编号:1672-7207(2011)S1-0647-04 Multi-frame super-resolution reconstruction algorithm based on fourth-order partial... second-order partial differential equations (PDE), a novel fourth-order PDE based method for SRIP was proposed, which is formed by incorporating the fourth-order PDE regularization in the image......
Influence of CeO2-ZrO2 and α-Al2O3 on Methane Partial Oxidation over Ni Catalyst费亚南,沈美庆,石芳丽,王军,翁端摘 要:The catalytic performance of Ni catalysts supported by CeO2-ZrO2 and α-Al2O3 was investigated for methane partial oxidation. Catalysts were measured by XRD. Carbon deposition was analyzed with TG-DTA and Raman. The results show that the activity......
Influence of Supports on Catalytic Performance and Carbon Deposition of Palladium Catalyst for Methane Partial Oxidation石芳丽11. Key Laboratory for Green Chemical Technology of State Education Ministry,School of Chemical Engineering & Technology,Tianjin University摘 要:The catalytic performance of methane partial oxidation was investigated on Pd/CeO2-ZrO2......
particular conditions or during partial remelting and holding for some time in the semi-solid state. During holding, the solid globules grow and usually also agglomerate in order to reduce the total solid... by X-ray tomography of the overall and local microstructural changes occurring during partial remelting of an Al-15.8 wt.% Cu alloy [J].
