Surface damage on highly oriented pyrolytic graphite induced by bombardment of 530 keV Au+ or 4.5 MeV Au++ at a low dose 1×1012 cm−2 was studied scanning tunneling microscopy. The most prominent surface features are hillocks with diameter about 1.8 nm. average spatial density the is in good agreement ion used, indicating that they impact individual incident gold ions. There also exists another type hillock (which called bump this paper) smaller and frequency twice dose. These small have...
Abstract To widen the application field of iron tailings (ITs) and explore ITs potential use‐value, aluminum phosphate (AHP) were introduced to prepare flame‐retardant rigid polyurethane foam (FR‐RPUF) composites. The chemical composition mineral investigated by X‐ray diffraction, fluorescence. flame retardancy, thermal stability, combustion performance gas‐phase products FR‐RPUF composites limiting oxygen index, underwriters laboratories vertical burning test (UL‐94), thermogravimetry (TG),...
The design of PVC-FRP confined concrete members requires accurate evaluation the performance enhancement due to confinement provided by tube. Based on static equilibrium condition and yield criteria tube, this paper presents a calculating model load-carrying capacity column, influences hoop spacing FRP strips equivalent effect coefficient were well considered. According ingression experimental data, formula ultimate axial strain is also put forward. For last case, bilinear stress-strain...
In recent years, the use of shielding gas to prevent diffusion ambient air, particularly oxygen and nitrogen species, into effluent atmospheric pressure plasma jet, thus control nature chemical species used in treatment has increased. this paper, radial propagation a jet Ar is examined find key determinants polarity jets. The dynamics discharge reveal that special phenomenon observed only at falling edge pulses. transport electrons, which driven by component applied electric field pulse,...
Abstract Low‐cycle reversed loading test were conducted on 10 circular steel tube confined reinforced self‐stressing slag concrete columns and four (SSC) columns, to investigate the influence of shear span ratio, axial compression diameter‐thickness ratio expansion SSC seismic performance specimens. The results indicated that crushing core at bottom yielding longitudinal reinforcement dominated specimens damage. Fine circumferential tensile cracks without development trend along height...
Plasma plumes have found a wide range of applications over the recent decade, stimulating studies characteristics plasma generated under different conditions. Regardless whether they propagate within dielectric tube or shielding gases, behavior these will be affected by boundary condition plume. Yet, at present, little is known about polarities, especially negative plumes, when propagating To bridge this gap, in paper, positive and quartz tube, ambient Ar, air are studied. The results reveal...
Abstract To fully use the expansion property of steel slag, an experiment on 10 self‐stressing slag concrete‐filled tube (SSSCFST) columns and four (SSCFST) subjected to low cyclic loading are implemented, effects ratio concrete, axial compression ratio, diameter‐thickness shear span seismic properties SSSCFST components analyzed. The outcomes present that failure mode specimens changes from bending bending‐shear as reduces. With improvement initial stiffness, strength degradation degree,...
An experimental study on the stress-strain relation of PVC-CFRP confined reinforced concrete columns subjected to eccentric compression was carried out. Two parameters, such as CFRP strips spacing and eccentricity axial load, were considered. The results showed that all specimens failed by compressive yield longitudinal steel bar rupture strips. bearing capacity specimen decreases or increases. stressstrain undergoes two stages: parabolic linear stages. In stage, slope curve gradually...
Monocrystalline silicon is typical of hard brittle materials, a high surface quality can be obtained in ductile-regime cutting. The success the turning process depends on optimizing machining parameters such as tool edge radius, rake angles, depth cut and cutting speed, etc. In this study, based ductile–brittle transition mechanism, optimization were determined with commercial, general purpose FEA software Msc.Marc. result demonstrates that value temperature minimum when angle range...
This paper presents an experimental study on nano-SiO2 reinforced straw fiber recycled aggregate concrete (NFRAC). The effects of content and particle size the failure mode stress-strain relationship are analyzed. Test results show that incorporation can effectively inhibit formation development cracks, reduce number cracks. As increases, compressive strength elastic modulus increases then decreases. optimum is 2%, at which time NFRAC increased by 27% 14.8% respectively compared with (FRAC)...
This paper analyzes the failure phenomenon and adjustment skill through basic introduces of principle Bourdon tube Type pressure gauge. The detect bourdon type gauge was discussed to make sure accuracy data measured by colleagues as reference. has already widely used in maintenance ground equipment, performance stable reliable quality will influence aircraft maintain quality. correct use debug determine measure We should analysis on structure principles cause problem, give repair method.
