The results show that the interplanar spacing of the (020) plane increased firstly then decreased, while the dislocation density decreased firstly then increased. The maximum and minimum values of the interplanar spacing and dislocation density are 2.39 nm and 0.31 nm-2, respectively when the annealing temperature is 80℃. When the annealing temperature improved above 80℃, the Fe/epoxy composites become dense without voids and the phase boundary between Fe and epoxy closes together. The size of Fe particle enlarged obviously from 15.58 μm to 18.26-21.74 μm when the annealing temperature improved from 60℃ to 80-120℃. When the annealing temperature increased from 60℃ to 80℃, the microhardness improved from 29.46 HV to 39.32 HV and sustained to 39.12 HV when the annealing temperature increased to 100℃, then decreased to 28.48 HV when the annealing temperature increased to 120℃.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As opposed to the conventional separation method, the membrane separation has received wide attention because of its advantages of green environmental protection, low energy consumption and easy operation. In this paper, Cu(OH)2 mesh with superhydrophilic and underwater superoleophobic properties were prepared by in-situ growth method using purple copper mesh as the substrate. Scanning electron microscopy, x-ray photoelectron spectroscopy and contact angle tests were used to evaluate the surface morphology, chemical composition and wetting behavior of the mesh. The results showed that the water contact angle was 0° in air and the contact angle was 155.4° for oil droplets underwater. The membrane exhibited high separation efficiencies (99%) and separation fluxes (3.67-6.54×104 L·m-2·h-1) for the five tested oils under gravity drive. The wettability of the mesh was unaffected after 20 separation experiments. The surface wettability and the oil/water separation mechanism were analyzed using the capillary force-based separation model combined with the Young and Cassie-Baxter equations.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

[Methods] In Caoxian County, Heze City, Shandong Province, a field experiment was conducted with rice as the test crop, and the biochar application rates were set at 0 t/hm2 (CK), 4.5 t/hm2 (C1), 9 t/hm2 (C2) and 13.5 t/hm2 (C3) treatments were used to determine soil water content, electrical conductivity, soil nutrients and agricultural runoff nutrients under different treatments, and to analyze the effects of biochar on rice yield, as well as its correlation with soil physicochemical properties and agricultural runoff nutrients. [Results] Compared with the control, the application of biochar had a significant effect on soil water content, and the increase of soil volume water content decreased with the increase of biochar application amount. In August and September, the soil conductivity treated by C1 and C2 was significantly higher than CK, and there was no significant difference in the rest of the rice growth period. The application of biochar could promote the absorption and utilization of soil nutrients, but had no significant effect on soil pH. C1 and C2 treatments generally increased the nutrient content of farmland regression water, and C3 treatments generally reduced the nutrient content of farmland regression water. The application of biochar could increase the yield of rice, especially the C2 treatment, which was 8.49%. The correlation analysis showed that soil total phosphorus, total potassium and available phosphorus were significantly positively correlated with rice yield, and soil nitrate nitrogen and SO2- 4 contents were significantly negatively correlated with rice yield. The total nitrogen, total potassium and nitrate nitrogen in agricultural runoff were significantly positively correlated with rice yield. [Conclusion] The application of biochar can increase soil moisture, affect soil nutrients and electrical conductivity, and help to increase nutrient content in new created cropland in the Yellow River basin, and can be used as a soil amendment for new created cropland in the Yellow River basin. The recommended application amount is 9 t/hm2.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the analysis of historical accident data, the occurrence mechanism of road transportation accidents of hazardous chemicals was discussed. Based on the bow-tie theory, the bow-tie diagram was established to realize the construction of qualitative reasoning bow-tie diagram for multi-disaster coupling accidents in road transportation of hazardous chemicals. The mapping rules between Bow-tie model and Bayesian network were established, and the structure of Bayesian network for road transportation of hazardous chemicals was constructed. The prior probability and conditional probability of Bayesian network nodes are determined by multi-source data, and the real-time accident probability evaluation is realized by combining quantitative and qualitative methods.

We estimate the Antarctic mass balance from 1985 to 2021 using an input-output method. Ice discharge is estimated using an automated algorithm, while surface mass balance data is obtained from the RACMO2.3p2 model. We find a recent decrease in the rate of ice mass loss in Antarctica, consistent with the recent studies. The West Antarctic Ice Sheet (WAIS) drives the increase in ice discharge and mass loss, influenced by rising ocean temperatures and extreme weather events. The East Antarctic Ice Sheet (EAIS) shows stability in mass balance, except for an increase in discharge and mass loss in the Cp-D sub-region. The Antarctic Peninsula experiences increased ice discharge and mass loss, while the islands maintain a positive mass balance. The findings contribute to our understanding of the ongoing changes in ice mass and highlight the sensitivity of different regions to external factors.","PeriodicalId":503577,"journal":{"name":"Advances in Computer and Engineering Technology Research","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cluster and feature data are obtained by Expectation Maximization process, and the isolated clusters are filtered out by the threshold parameters of weight and the Euclidean distance between clusters center. Based on the feature data, a scoring strategy is established to assess the bridge health and sensor status. The proposed strategy is used to analyze the monitoring data of a bridge in western China, and the analysis results show the availability of this strategy. Compared with the directly collected data, the processed bridge health scoring curve variation is smooth, which can reduce the influence of noise and abnormal data. The sensor status scoring curve can track changes in collected data and respond to different transformation scenarios.

Being restricted by various objective factors such as lack of data and complicated formation mechanism of flash flood disasters in small watersheds, accurate and targeted early warning has consistently been a weak link within the flash flood control system. In this regard, focusing on a series of problems, such as \"short risk forecasting period\", \"frequent missing and false reports\" and \"poor early warning accuracy\", this research explores a hierarchical partition management system that fulfills the demands of early warning based on the analysis of watershed lag time and risk situation. Meanwhile, based on the comprehensive consideration of the characteristics of various multi-source early warning data, such as meteorological forecast rainfall and monitoring rainfall water level, this research proposes corresponding early warning modes for different types of early warning objects. On these grounds, this research applies the proposed early warning system to Xiaguan Creek in Shangyu District, Zhejiang Province.
