The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, amount deposited storage yard adds up to 30Mt, leading occupation farm land and serious pollution environment. Improving an important way resolve these problems. physical chemical characteristics were analyzed then research progress at home abroad as recycled raw material enterprise interior, aggregate road hydraulic construction, cement additive concrete admixture, materials for...
Abstract The Li metal is an ideal anode material owing to its high theoretical specific capacity and low electrode potential. However, reactivity dendritic growth in carbonate-based electrolytes limit application. To address these issues, we propose a novel surface modification technique using heptafluorobutyric acid. In-situ spontaneous reaction between the organic acid generates lithiophilic interface of lithium heptafluorobutyrate for dendrite-free uniform deposition, which significantly...
Parallel joints are ubiquitous in geological rock mass and seriously affect excavation underground mining civil engineering. In this study, the propagation characteristics of shock waves subjected to blasting load a parallel jointed were investigated using field testing three-dimensional finite-element numerical modeling. The method instantaneous energy was first adopted mine recorded information about interaction between joint planes waves; then, displacement discontinuity (DDM) used for...
The China Society of Explosives and Blasting required a larger than 20% annual increase in the national use digital electronic detonators since 2018. So, this article conducted large number on-site tests then used Hilbert-Huang Transform method to analyze compare vibration signals nonel during excavation process minor cross-sectional rock roadways from perspective time, frequency, energy. Then, through energy analysis, identification actual delay formula derivation, it was proved that time...
Abstract In term of the global random attractors theory, dynamics nonlinear stochastic heat conduction driven by multiplicative white noise with a variable coefficient are investigated numerically. It is shown that 𝒟-bifurcation, secondary 𝒟-bifurcation and complex dynamical behavior occur in motion system increasing intensity linear component source. Furthermore, results obtained here indicate Hasudorff dimension which relevant to Lyapunov exponent can be used describe associated qualitatively.
The quality of seedbed after sowing such as soil surface roughness is one the key factors affecting seedling emergence rapeseed, which ultimately affected crop yield. However, effect on and yield rapeseed still unclear. In this study, field experiments at experimental site Jianli Shayang were carried out. Three treatments designed: relative slow (M1), medium (M2), fast (M3) forward speed unit. Soil measured by a 3D laser scanner, seed quantity seeder, rate determined to investigate rapeseed....
The coastal micro-confined aquifer (MCA) in Shanghai is characterized by shallow burial depth, high artesian head, and discontinuous distribution. It has a significant influence on underground space development, especially where the MCA directly connected with deep confined aquifers. In this paper, series of pumping well tests were conducted located such area to investigate dewatering-induced groundwater fluctuations stratum deformation. addition, numerical method proposed for estimation...
Highlights The relationship between the angle of repose and compound fertilizer particle size distribution sphericity was revealed. range rolling friction coefficient obtained by different modeling calibrated golden section method. Scanning required 80% spherical to reflect actual motion. relative error scanning (7.91%) better than that (30.84%). Abstract. discrete element method (DEM) is widely used simulate behavior granular materials. accurate establishment model has a great influence on...
