The purpose of this study is to the effect CO2-N2 composite gas on coal spontaneous combustion index and mechanism inhibiting through a competitive adsorption process provide theoretical guidance for adopting inert injection fire prevention control technology in goaf prevent combustion. programmed temperature experiment chromatography were used analyze indicator after injecting different mixed ratios CO2 N2 gas. In whole oxidation heating (25–300 ℃), generation peak point ratio showed an...
Gait generation method is one of the important contents snake robot motion control. Different gait methods produce completely different forms control functions, so robots need more complicated programming logic and processes to realize various gaits their transformation. Therefore, we propose a new unified expression method, The MCC (main characteristics control) simplifies unifies functions by extracting main features backbone curves gaits. Since all periodic that meet Dirichlet conditions...
To enhance the performance of pulverized coal combustion, a composite combustion aid was prepared by physical mixing method using preferred blend particular enterprise as raw material. The effects different proportions aids (light-burnt dolomite (LBD), Fe2O3, and CeO2) on catalytic reactivity were studied synchronous thermal analyzer, enhanced characteristics, kinetic parameters, release characteristics examined. results showed that with ratios had combustion-enhancing coal; consisting LBD,...
This cross-sectional survey, utilizing a convenience sampling method, was conducted to investigate compassion fatigue (CF) among pediatric nurses in Shenzhen, China. Early identification of factors influencing is critical issue that nursing managers must address urgently. A technique employed, and 539 from tertiary grade hospitals Shenzhen were assessed using the Professional Quality Life Scale. Logistic regression analysis subsequently identify fatigue. total 534 valid questionnaires...
Understanding the adsorption mechanism of CO2 fluid on porous media is significant for developing efficient adsorbents. This study modified carbon aerogel (CA) nanoparticles with N-methylethanolamine (MMEA). The surface functional groups and pore properties samples were characterized, flow behavior fluids under different pressures in pores studied. results showed that aerogel's amine oxygen-containing group content increased increase MMEA loading but decreased its specific area volume....
Hydromechanical coupling in rock masses is an important issue for many mechanics and hydrogeology applications. The change of a water-bearing state will induce the fracture intact rocks further accelerate shear slip instability sheared surface. To investigate weakening effect water content on mechanical properties mass, laboratory direct tests combined with three-dimensional analysis surfaces were carried out sandstone samples different contents. variogram parameters, sill range, applied to...
The gait-based control allows the snake robot to move through different environments. flexible gait transition motion will effectively improve its application in complex To flexibility of control, this letter proposes a variety motions, which extend network for robots. Firstly, cost function is designed guide parameter conversion within parameterized gaits based on sine wave function. Secondly, we choose crawler as basis carry out design, including static from serpenoid gait, and dynamic...
Compared with mining the horizontal coal seam and gently inclined seam, steeply very thick has many differences.Since fracture development law is not clear, resulting in application effect limitation of gas extraction, prevention control air leakage other technics.In order to improve efficiency extraction leakage, laboratory similarly model test numerical simulation were adopted study overburden rock fracture, results was identical.The result showed that: Its a typical "V" structure, roof...
