Abstract To investigate the influence of chemical weathering on CO 2 consumption, an analysis was performed water chemistry by applying equilibria methods in Bishuiyan subterranean basin, SW China. The average value total ion concentrations (TZ + ) 1,854.97 μEq/L, which significantly higher than global = 1,250 μEq/L). Ca 2+ and HCO 3 − were main ionic constituents waters. SO 4 2− NO relatively other anion concentrations, Cl consistently lowest. Dissolved load balance models result showed...
Methods to fabric defects detection are varied, but the common method detect defect shapes is slow and poor accuracy. Based on wavelet transform neural network convergence technologies, this paper presents a new defect, which takes full advantage of good time-frequency localization characteristics multi-scale image analysis capabilities extraction, technology can against for precise identification rapid detection.
Osteoarthritis (OA) is a common joint disease for which safe and reliable treatment has yet to be developed. Here, we demonstrated the potential benefit of with paeonol, derivative Paeonia suffruticosa, in prevention OA. Chondrogenic cell line ATDC5 cells were cultured IL-1β effects paeonol assessed through qRT-PCR, western blot analysis, MTT, ELISA, NF-κB luciferase reporter gene assay. Our findings demonstrate novel ability inhibit numerous factors OA, including expressions IL-6, TNF-α,...
Based on the study of groundwater source heat pump air conditioning system, thermodynamic characteristics water system are analyzed in detail. This paper analyzes energy saving optimization a new type underground making more efficient and saving. theory thermal economics quantitative analysis, five independent variables selected as variable parameters economic analysis after designing objective function. The exergy efficiency under several values discussed, then comparative is carried out....
Through the characteristics of acoustic emission parameters and time process in rock stress test, it explored whole deformation until failure, found relations rocks stress-strain energy between failure. comparative we can find that, rate have direct loading different rocks, but size not with emission. Finally rule change curve through granite limestone compression test.
The karst process acts as carbon sequestration for atmospheric CO2. amount of (KCS) depends on the discharge catchment and inorganic concentration water body. Based data from monitoring station Banzhai subterranean stream located in Maolan National Nature Reserve Guizhou province, influence factors KCS have been analyzed. It shows that is about 353 t C per year stream, there good linear relationship between strength at various time scales. Therefore, how to monitor accurately key estimation...
The constitutive relation such as shear strength and optimal anchoring angle of jointed rock masses are obtained by analyzing the bolt grouting mechanism mine fracture masses.The roadway double-track is simulated respectively Flac3D software under condition no-support bolting grouting.The simulation results show that support with enhances bearing capacity roadway, improves stress station, limits deformation rock.
The positioning method based on ultra-wideband (UWB) technology has been widely used in real life. In order to improve the indoor accuracy of UWB, a new algorithm is proposed. Firstly, aspect non-iterative method, weighted least squares (WLS) proposed solve problem that traditional (LS) cannot take into account factors affecting system due different location base station system. Secondly, terms iterative closed-form Newton considering high-order view factor Gauss-Newton only performs Taylor...

Roadway bolt supporting, which relates the equations such as ground stress, mechanical property of surrounding rock and supporting structure, is an engineering problem structure coupling. Three-dimensional developing entry aided design system was developed by using ANSYS finite element software. Supporting function mechanics coal roadway analyzed calculated. The effects under similar conditions on deformation, stress displacement field around were mainly studied. simulation results applied...
In order to overcome the difficulty in real-time effectively acquiring target parameters of differential game guidance a complex underwater environment,the nonlinear tracking control based on continuous time generalised predictive correction is proposed.Since parameter and detection precision are seriously affected by acoustic homing device period,noise,and interference,it easy lose or misjudge signal.Hence combination dynamic model for games method used making on-line prediction...
