Mg-based amorphous alloys exhibit efficient catalytic performance and excellent biocompatibility with a promising application probability, specifically in the field of azo dye wastewater degradation. However, problems like difficulty preparation poor cycling stability need to be solved. At present, applied degradation are available powder ribbon. The alloy fabricated by ball milling has high specific surface area, its reactivity is thousands times better than that gas atomized powder. But...
Heavy metal pollution in agricultural soils poses a serious threat to food security. Therefore, it is crucial conduct risk assessments and issue early warnings about high levels of contamination for the sustained prosperity agriculture. To assess risks, identify sources, quantify amounts, determine extent from seven heavy metals, as well provide warnings, 78 soil samples were collected farmed lands Songnen Plain Jilin Province. The average concentrations Zn, Cu, Mn, Pb, Cd, Ni, As found be...
In order to analyse the heat and mass transfer characteristics of materials in a horizontal drum dryer, discrete element method (DEM) was used calculate particle collision model DEM-CFD coupled model. With increase rotating speed, mixing degree gradually increases, when speed is 16 rpm, higher. When flux EDEM-CFD coupling 0.2 W-1W, temperature will tend fixed value. The residence time material has great influence on drying quality particles. If too short, be uneven, if long, damage particles...
To investigate the levels of polychlorinated biphenyls (PCBs) in black soils Northeast China, we collected 59 surface soil samples from central region Jilin Province. We analyzed concentrations and sources seven PCBs soil, assessed ecological risks associated with PCB contamination, provided a risk assessment for this type. The mean (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153, PCB180) were as follows: 1.61 μg/kg, 10.61 0.37 4.11 0.70 1.07 2.09 respectively. Principal component analysis...
Axial piston pumps have been extensively applied in hydraulic systems, and their reliability takes on critical significance the stable operation of entire system. How to extract fault feature parameters identify faults axial turns out be vital ensuring safety In this study, a diagnosis method multi-sensor information fusion for is proposed based improved wavelet packet decomposition (WPD) kernelized support tensor training machine (KSTTM). Four-layer WPD utilized obtain different frequency...
A bearing fault is one of the major causes rotating machinery faults. However, in real industrial scenarios, harsh and complex environment makes it very difficult to collect sufficient data. Due this limitation, most current methods cannot accurately identify type cases with limited data, so timely maintenance be conducted. In order solve problem, a diagnosis method based on fractional Siamese deep residual shrinkage network (FO-SDRSN) proposed paper. After data collection, all kinds...

Soils in the Black Soil Zone of northeast China are experiencing pollution from polycyclic aromatic hydrocarbons (PAHs) as region undergoes urbanization. In this study, 119 topsoil samples were collected black soil agricultural area Jilin Province, to investigate characteristics and spatial distribution 16 PAHs. The total concentration ∑16 PAHs soils ranged 2.546 33.993 mg/kg, with a mean value 9.99 mg/kg. Positive matrix factorization (PMF) analysis indicated that vehicle exhaust oil...
In this paper, Cu-Fe powder metallurgical alloys were firstly fabricated, and a innovative surface modification technique, high current pulsed electron beam (HCPEB), was then irradiated these with 5 10 pulses. The morphologies, microstructure mechanical properties of the specimens both before after HCPEB irradiation studied. morphologies revealed that 5-pulsed sample melted completely, large amount craters formed. Those eliminated fused by subsequent 10-pulsed processing. Besides,...
Anxiety disorders (AD) are critical factors that significantly (about one-fifth) impact the quality of life (QoL) in patients with epilepsy (PWE). Objective diagnostic methods have contributed to identification PWE susceptible AD. This study aimed identify AD by constructing a model based on phase locking value (PLV) and Lempel-Ziv Complexity (LZC) features electroencephalogram (EEG).
The transient characteristics of load rejection process in pumped-storage hydropower (PSH) stations have a close relation to the safety electric power system and hydraulic facilities.
