in the central area of the workpiece at different three points and then it was arithmetically averaged. The reason to adopt this way is that the measured surface roughness values are a little difference...Trans. Nonferrous Met. Soc. China 22(2012) s845-s850 Mathematical model determination for improvement of surface roughness in magnetic-assisted abrasive polishing of nonferrous AISI316 material Jae......

It defines a medium access control layer that supports various physical layers...Optimal allocation of random access period for wireless body area networkJin hyuk KIM, Chang ki HONG, Sang bang CHOI(Department of Electronic Engineering, Inha University, Incheon 402-751, Korea......
of the most important functional traits, specific leaf area (SLA, defined as biomass investment per unit of light-capture surface area) can indicate the resource-use strategy of plants [1, 6]. Generally, high... those of native species. Additionally, the specific leaf area (SLA) values of invasive plants were remarkably lower than those of native species. Plasticity indexes of SLA, maximum branch angle......
, the specific surface area 0.275 m2/g, brightness 91.00, and density 2.70 g/cm3. Sodium stearate(SDS) used in experiments was chemical pure reagent, and the distilled water was used. 2.2 Test and evaluation... of SDS dosage and particle size on modification effect (Medium size, specific surface area: 1-6.33 mm, 0.275 m2/g; 2-1.33 mm, 2.315 m2/g; 3-0.94 mm, 3.133 m2/g; 4-0.77 mm, 4.021 m2/g) The particle size......
, Chongqing 400044, China)Abstract:Air content, spacing factor and specific surface of fresh concrete and hardened concrete with different air contents, slumps and mineral admixtures (fly ash, slag, fly... methods were analyzed. The results show that, there is a close correlation of air content and spacing factor between the fresh concrete and the hardened concrete, but the specific surface correlation......
process and characterized by means of X-ray diffraction (XRD), laser Raman spectra (LRS), UV-visible diffuse reflectance spectra (DRS), specific surface area (BET), and transmission electron microscopy... surface area increases owing to doping Y2O3. Y2O3/TiO2 samples have a larger specific surface area and higher thermal stability. Owing to quantum size effect, the reflectance of Y2O3/TiO2 samples is larger......
] made much contribution in this field. However, there are a few reports about γ-Mo2N applied as charge storage materials. Owing to the high activity and high specific surface area, it is not surprising... make full use of inner surface area, which makes much contribution to the capacitance. Fig.5 Relationship between scan rate and specific capacitance of γ-Mo2N in 1 mol/L H2SO4 We also obtain that kd......
