合管；力学性能；吸能性能 中图分类号:TB 339 文献标识码:A Compression capability and energy absorption of foam aluminum cylinder sandwich with silicone rubber LIN Sen, FENG Yi, ZHA Hai..., then cylinder sandwich was produced when using foamed aluminum filled with silicone rubber as core, aluminum tube and steel tube as panel. The compression deforming activity and energy absorption ability......
. It was proved to be useful in the selection of the optimal-density and energy absorption foam for a specific application at impact events. Key words: elasto-plastic; constitutive model; metallic foam; strain rate effect; energy absorption 1 Introduction Cellular materials, such as metallic foams, can dissipate considerable energy by large plastic deformation under quasi-static or dynamic......
Abstract: The buckling resisting brace (BRB) is an efficient system against lateral loads that enjoy high seismic energy absorption capacity. Although desirable behavior of BRBs has been confirmed... stiffness, and energy absorption. Besides, the DK configuration reduces the axial forces created in columns in the nonlinear zone. Reducing material demand, created forces in the main frame, and also......
. Based on the collapse characteristics of aluminum square section member, the collapse characteristics and energy absorption capability of hat-shaped section members were analyzed. The axial static collapse tests were carried out for each section member. The collapse modes and the energy absorption capability of the members were analyzed. In the lightmass design aspect, the collapse characteristics......
absorption near-edge structure (XANES). The results show that the dissolution rate of chalcopyrite is higher when the redox potential is less than 400 mV (vs SCE), and above that potential... that the mixed culture promotes the formation of chalcocite and obviously restrain the passivation layer (sulfur and jarosite). Key words: sulfur-oxidation; X-ray absorption near-edge structure......
, Zhejiang University, Hangzhou 310027, China) Abstract:We have calculated the sulphur 1s near edge X-roy absorption fine structure (NEX-AFS) spectra of SO2 adsorbed on Pd( 111 ) in terms...-.factor) analysis are employedto determine the local adsorption structures. These results are broadly in agreementwith those of Fourier-transform analysis of the surface extended X-ray absorption......

The effect of oxygen partial pressure on the morphology, crystallinenature, chemical composition and optical absorption......
Optical Absorption Properties of Electron Beam Evaporated a-Si1-xGdx Films甘润今,张仿清,张津岩,刘国汉,陈光华摘 要:<正> Optical absorption properties of electron beam... to a change in near infrared absorption.For 0.1 at%<x<1.0 at%,the changes of op-tical absorption in the films are more sensitive.The optical band gap narrows with increasing content x from 1.52to 1.36......
to improve the moisture absorption and desorption performance, and then kinetic experiments of moisture absorption/release on the humidity-controlling composite materials were carried out with the help..., and the effects of the moisture absorption/release of humidity-controlling composite material were discussed. The results show that the product has higher hygroscopic capability, easier regeneration......
absorptive amount and absorption rate of master alloys (f) 图2 含P中间合金细化后Al-18Si合金的金相组织 Fig. 2 Microstructures of Al-18Si alloys after modified by master alloys containing P 图2(a)~(f)所示依次为未细化和分别以..., P absorption rate and P equilibrium solubility in Al-18Si melt under different holding temperatures 根据LESCUYER等[21]利用控温过滤仪器研究的Al-Si熔体中P的溶解度随温度变化的曲线,可以看出,P在Al-Si熔体中的溶解度十分有限,为10-5数量级.其溶解度的数学表达式如下: ......
