Urban agglomeration is a new carrier of regional economic development, whose spatial structure can be reflected by the transportation system. The coordination between urban development and system conducive to promoting balanced development. As an important cluster China, Harbin-Changchun plays role in revitalization northeast China. Targeting 11 cities agglomeration, this paper adopts coupling degree model study level results show that large differences exist among cities, with Changchun at...
The development of deterministic models for predicting the accumulation corrosion damage to zirconium and Zircaloys in boiling water reactor coolant environments requires acquisition values various model parameters. In present work, point defect (PDM) was further developed account properties passive films comprising oxide barrier layers porous outer that form on high-temperature, deaerated aqueous solutions. parameter were extracted from electrochemical impedance spectroscopic data...
People-oriented urban planning requires that service facilities should efficiently meet individual and community activity needs across the demographic landscape defines a city. To develop conceptual basis for spatial infrastructure optimization, we empirically studied existing population activities in Changchun, China, using kernel density estimation, bivariate autocorrelation analysis, other models. The relationships derived from multiple sources of big data such as mobile phone signaling...
Water scarcity has become a major impediment to economic development, and scientifically sound water allocation plan is essential alleviate scarcity. An opportunity constraint approach introduced optimise the uncertainty of minimum regional development level under five hydrological scenarios, an interval-fuzzy two-stage chance-constraint model (IFTSC) constructed improve reliability results. The correlation each stochastic parameter in IFTSC with results benefits Tingjiang River basin...
The development of deterministic models for predicting the accumulation corrosion damage to zirconium and Zircaloys in pressurized water reactor (PWR) coolant environments requires acquisition values various model parameters. In present work, point defect (PDM) was further developed account properties passive films comprising hydride barrier layers porous oxide outer that form on high-temperature, hydrogenated aqueous solutions. parameter were extracted from electrochemical impedance...
We employ molecular dynamics (MD) simulations to study the structure of vitreous boron oxide. Although six-membered boroxol rings have been observed at fractions over 60% by various experimental techniques, simulation methods not produced similar results. adapt polarization model, which includes many body effects thought stabilize such structures, for boron–oxygen interactions. This model is then used in MD oxide glass temperatures. find a variation fraction depending on temperature system...
Abstract This paper explores the rheological characteristic and molecular mechanism of polymer melts during extrusion when ultrasound is applied to them at entrance die. Applying disturbs convergent flow melt in entry zone changes stream patterns, which leads lesser elastic tensile strains happen. It also activates chains, so that can be recovered very quickly. That why Δ P measured reduced. These conclusions are made based not only on calculations but looking‐inside characterizations...
Abstract The processing of ultrahigh molecular weight polyethylene (UHMWPE) by the addition polypropylene (PP) and high‐density (HDPE) was investigated. results show that PP improves processability UHMWPE more effectively than does HDPE. UHMWPE/PP blends can be processed with a twin‐roller general single‐screw extruder. In extrusion blends, is enriched at surface blend adjacent to barrel wall, thus increasing frictional force on wall; conveyance solid down channel then carried out. melt pool...
Abstract The effects of ultrasonic irradiation on the mechanical properties, morphology, and crystal structure polypropylene (PP)/ethylene‐propylene‐diene terpolymer (EPDM) blends were examined. Results show that appropriate intensity can noticeably increase toughness PP/EPDM without reducing rigidity. Scanning electron microscopic (SEM) observation shows with irradiation, morphology a well‐dispersed EPDM phase is formed in blend. glass transition temperatures PP approach each other as...
The Momoge National Nature Reserve (MNNR) is located at the intersection of Nenjiang and Taoer Rivers in Baicheng City, Jilin Province, where River main source water for nature reserve. However, due to construction control project upper reaches River, MNNR has been a state shortage long time. To guarantee wetland function reserve, government planned carry out normal flood supply from through West Water Supply Project Province. Therefore, how improve utilization resources effectively become...
Magnetic pulse welding realizes solid-state connection through a high-speed collision of materials, which can effectively overcome the difficulties light metal materials. In magnetic system, in order to improve efficiency, field shaper is usually applied between multi-turn coil and workpiece concentrate area, thereby improving electromagnetic force. However, large number researchers are currently on tube-welded shaper, very few have studied structure plate-welded shaper. Therefore, this...
Abstract The rheological and processing behavior (melt fracture performance) of polystyrene extruded through a slit die is studied as function the ultrasound vibration intensity. apparent viscosity reduces 29% pressure 22% compared with that without vibration. melt decreases exponentially intensity increases an Arrhenius equation fits data well. Ultrasound also leads to decrease swell ratio postponement melts fracture. Characteristic relaxation times at onset are calculated according...
Abstract The effects of ultrasonic irradiation on the rheology, structure, and properties PP/inorganic filler composites were studied. Scanning electron microscopy showed that ultrasound increased orientation degrees acicular fillers to flow direction. WAXD indicated vibration induced sheet orient with its surface perpendicular direction vibration. orderly rearrangements in polymer melt by can reduce steric hindrances field increase flowability composites. effect reducing apparent...
In this work, based on the upper line of water resources utilization and bottom environmental quality "Three Lines, Single Project", a fuzzy optimization method was introduced into Tingjiang River optimal allocation eco-compensation mechanism model, which is interval two-stage (ITS) stochastic programming method. addition, model (IFTS) also constructed. The objective functions both models were to maximize economic benefits River. available in basin, requirements, regional development...
