Robust control of gantry crane system with hoisting: A new solution based on wave motion YANG Tang-wen(杨唐文)1, 2, QIN Yong(秦勇)2, HAN Jian-da(韩建达)3 (1. Institute of Information Science, Beijing... Institute of Automation, Shenyang 110016, China) Abstract: Large load swing of a gantry crane, due to cable flexibility and rapid movement, needs to be controlled. Herein, a wave-based approach interprets......
J. Cent. South Univ. Technol. (2008) 15: 176-182 DOI: 10.1007/s11771-008-0034 -7 Fast preparation of photopolymerized monolithic columns for capillary electrochromatography GONG Wen-jun(龚文君)1... capillary (75 mm inside diameter) to prepare the porous monolithic sol-gel column by a one-step, in situ, process. The chromatographic behavior of the eight PSG columns were comparatively studied, all......
Influence of Absolute Basicity and Capillary Porosity on Carbonation of Concrete巴明芳摘 要:The single influence of capillary porosity and coupling effects of absolute basicity and capillary porosity on concrete carbonation were investigated. The experimental results showed that carbonation rate of concrete at a given absolute basicity (AB) increased......
diagram of capillary rise of tailings dam 通常毛细水上升高度主要采用室内试验[22]和现场试验[23]来确定,关于毛细水上升高度,国内外学者做过许多相关的研究,并提出了诸多估算公式和测定方法,如含水量试验法[24],水分特征曲线法[25]等.但现行比较通用的估算公式为海森公式[26]:  ...保证试样装填均匀,并通过刻度及装填质量计算维持一定的干密度.然后将装有尾矿的有机玻璃柱移入水槽内.打开注水装置的控制阀使溶液进入水槽,并控制水流速度,保证水恰好与尾矿样底部接触,利用虹吸原理保证水槽水位(相当于尾矿坝中的浸润面高度)不变. 图3 毛细水上升试验装置示意图 Fig. 3 Schematic diagram of capillary water rising......
Wave impedance of W-Mo system compositeQiang Shen, Lianmeng Zhang, Hua Tan, and Fuqian Jing1)Laboratory for Shock Waves and Detonation Physics Research, Chinese Academy of Engineering Physics...> W-Mo composites with different mass fractions of W and Mo were prepared at 1473 K by Spark Plasma Sintering technique. The transverse and longitudinal wave velocities of the samples were......
