J. Cent. South Univ. (2012) 19: 2179-2186 DOI: 10.1007/s11771-012-1262-4 Acid-pickling plates and strips speed control system by microwave heating based on self-adaptive fuzzy PID algorithm YANG Biao... to construct quasi-cascade control system to control the speed of the acid-pickling process of titanium plates and strips. It is very useful in overcoming non-linear dynamic behavior, uncertain and time......
selected to inject air into water and to produce different bubble sizes. High-speed photography in conjunction with an in-house bubble image processing code was used. During the evolution of the bubble... in Figure 4 contain typical bubble profiles at the initial stage of bubble evolution after the bubble departs from the nozzle. Since the nozzle exerts a boundary effect on the bubble at the moment......
can improve the electrocatalytic activity of anodic oxide. The anode containing 3% β-PbO2 had the lowest overpotential of oxygen evolution reaction (OER) and the best corrosion resistance. The morphologies of the anode surfaces were gradually transformed from regular crystals to amorphous ones as the content of β-PbO2 increased in anodes. Key words: power-pressed Pb-Ag-PbO2 anode; oxygen evolution......
J. Cent. South Univ. Technol. (2008) 15: 484-487 DOI: 10.1007/s11771-008-0091-y Relationship between initial efficiency and structure parameters of carbon anode material for Li-ion battery SHEN...; Abstract: The initial efficiency is a very important criterion for carbon anode material of Li-ion battery. The relationship between initial efficiency......

strain work hardening and textures [J]. Progress in Materials Science, 1981, 25: 69-134. [15] LEE J, JEONG H. Effect of rolling speed on microstructural and microtextural evolution of Nb tubes during... at high extrusion ratios. The increase in hydrostatic pressure on the Nb tubes contributed to texture evolution in terms of extrusion ratios due to the difference between {110}<111> and {112}<111......
