High-quality aircraft assembly is critical in manufacturing. To meet increasing quality demands, the process needs to be monitored real time. In recent years, digital twins have attracted interest different applications. However, due heterogeneous data and multiple protocols field, large amount of satisfy high throughput, low latency, storage cost requirements without interrupting process, which introduces challenges real-time monitoring systems. this article, a system based on twin that...
Three kinds of drag reducer were synthesized by inverse emulsion polymerization and named PHWAM-1, PHWAM-2, PHWAM-3. Drag reduction (DR) tests showed that the three reducers have different DR characteristics in fresh water various saline waters because their types hydrophobic monomers. without monomers, performs better water, while PHWAM-2 PHWAM-3, with perform brine. In addition, which has twin-tailed best high-concentration Measurements micro-particle size observations spatial structure...
The Tibetan Plateau is known as the “Third Pole”. However, there are few studies on clear-air turbulence (CAT) event over Plateau. On 11 February 2023, a severe occurred along Lhasa-Chongqing route. To verify role of mountain waves in this aircraft event, using ERA5 reanalysis data and Weather Research Forecasting (WRF) Model, characteristics generation mechanisms investigated. In synoptic features, warm advection lower troposphere benefits atmospheric instability, promoting development...
Quinoline is a typical nitrogenous heterocyclic compound, which carcinogenic, teratogenic, and mutagenic to organisms, its wastewater difficult biodegrade directly. The bipolar electro-Fenton process was employed treat quinoline solution. process/reaction conditions were optimized through the single factor experiment. degradation kinetics of chemical oxygen demand (COD) analyzed. To get mechanism pathways quinoline, intermediate products identified by gas chromatograph–mass spectrometer...
Abstract In this study, a total of 339 mesoscale convective systems (MCSs) are obtained in North China using the temperature brightness blackbody (TBB) data from FY-2E warm season 2010 to 2018. The number meso-α-scale (MαCSs) is much more than that meso-β-scale (MβCSs). elongated (MECSs) circular (MCCSs). Most MCSs occur July and August, which have widest influence range, longest duration, strongest convection. MαCS develops slowly weakens rapidly. diurnal variation MαCSs presents bimodal...
The southwest vortex (SWV), a low-pressure system bringing severe rainfall in China, is one of the most important synoptic systems China. Using both National Centers for Environmental Prediction Final (NCEP-FNL) operational global analysis dataset and Weather Research Forecasting (WRF) model simulation, sophisticated SWV with dual-core structure (DCSWV) over Sichuan Basin 2010 was studied. DCSWV consisted two cores, near Leshan City (named “C1”) another Langzhong “C2”). high-resolution WRF...
通过透射电子显微镜（TEM）和扫描电子显微镜（SEM）观察，硬度测试和电化学测试等方法研究了一种新型锂离子电池外壳材料含铈（Ce）Al-Cu-Mn合金的组织和性能.试验结果表明：合金中主要含有α-Al相，Al 2 Cu和Al 12 （Mn，Fe） 3 Si相.铸态合金中含有大量的Al-Mn-Fe-Si或者Al-Cu-Mn-Fe-Si和Al-Cu-Si-Ce中间相；Tafel极化曲线测试结果表明，腐蚀处的形貌主要由腐蚀环和腐蚀产物组成.随着Cl - 浓度的增加，合金的耐蚀性能下降.交流阻抗谱分析表明，随着浸入溶液时间的增加，从高中频容抗弧和韦伯阻抗组成的曲线转变成单一的容抗弧，合金转变为全面腐蚀.
The aircraft tooling positioner serves as the reference for positioning during component assembly, and its global displacement state directly affects assembly accuracy. Thus, it is critical to monitor of in real-time ensure efficient accurate assembly. In this study, a reconstruction method based on sparse point measurement proposed. Using only four points within narrow nearly enclosed space, high-precision online monitoring can be achieved. Firstly, principle modal superposition model...
mLLDPE(metallocene polyethylene)/LDPE/CB(conductive carbon black) composite with positive temperature coefficient(PTC) was successfully prepared by blending. The rheology behavior and the strength of PTC composites were investigated through methods rheometer test, resistance measurement, scanning electronic microscope (DSC) electron (SEM) analysis. results showed that CB can be uniformly dispersed in mLLDPE / LDPE composite; mLLDPE/LDPE/CB has higher than this LDPE/CB composite. mutations...
Binocular stereo vision technology plays an essential role in the intelligent manufacturing system due to advantages of high accuracy and non-contact. However, for measurement components with highly reflective surfaces such as metal ceramic, specular reflections affected by complex light field lead failure feature matching decrease accuracy. This paper proposes imaging strategy binocular a dynamic image processing method suppress effect reflection matching. Firstly, mechanism highlight...
