Lessening energy-related carbon emissions has become a crucial measure to achieve Chinese carbon *** study is the first to construct a Difference in Carbon pressures-adjusted Human Development Index(DCHDI)model for the purpose of exploring the coupling effect between carbon emissions and human development variety from 2000 to 2019 in Chinese *** demonstrate the following.(1)The total energy-related carbon footprint of 30 provinces in China reached 10.2 billion tons in 2019,with an average annual growth rate of 6.93% over the past two decades;and the provinces with the highest carbon emissions per capita are InnerMongolia,Ningxia,and Shanxi.(2)At the provincial level,we observed that the Human Development Index(HDI),which includes life expectancy,education,and income,has been rising,while Beijing,Shanghai,and Tianjin entered the super-high HDI level before 2008.(3)The entire coupling effect of 30 Chinese provinces has been broadly fortified in the last 20 years,but the growth rate of DCHDI values in 2011-2019 has slowed down compared with that in 2000-2010;the clustering phenomenon demonstrated that this discovery is associated with historical peaks in total carbon emissions.(4)The co-ordination degree of carbon emissions per capita and HDI was verified,and 96% of the data points were found in the range of super high coupling coordination ***,this study provides the government with worthwhile guidance for decision-making and carbon reduction strategies for other countries struggling to advance human sustainable development.

Frontiers of Environmental Science & Engineering 2022年第12期16卷 79-88页

A novel permeable reactive barrier(PRB)configuration,the so-called passive convergence-permeable reactive barrier(PC-PRB),is proposed to overcome several shortcomings of traditional PRB configurations,such as high dependency to site hydrogeological characteristics and plume *** PC-PRB is designed to make the plume converge towards the PRB due to the passive hydraulic decompression-convergent flow *** corresponding passive groundwater convergence(PC)system is deployed upstream of the PRB system,which consists of passive wells,water pipes,and a buffer layer.A two-dimensional(2D)finite-difference hydrodynamic code,entitled PRB-Flow,is developed to examine the hydraulic performance parameters(i.e.,capture width(W)and residence time(t))of *** is proved that the horizontal 2D capture width(Wh)and vertical 2D capture depth(Wv)of the PC-PRB remarkably increase compared to that of the continuous reactive barrier(C-PRB).The aforementioned relative growth values in order are greater than 50%and 25%in this case ***,the PRB geometric dimensions as well as the materials cost required for the same plume treatment *** sensitivity analysis reveals that the dominant factors influencing the hydraulic performance of the PC-PRB are the water pipe length(Lp),PRB length(LPRB),passive well height(Hw),and PRB height(HPRB).The discrepancy between the Wh of PC-PRB and that of the C-PRB(i.e.,∆Wh)has a low correlation with PRB parameters and mainly depends on Lp,which could dramatically simplify the PC-PRB design ***,the proposed PC-PRB exhibits an effective PRB configuration to enhance hydraulic performance.

人类在探索利用AI进行审美评估的过程中,先后尝试了偏重专家意见、偏重大众意见和偏重用户个人喜好等多种途径,但至今未能确立一个被广泛认可的评价标准。人脑结构与机能的复杂性、社会文化的多样、人类处于不同场域中的情感落差、数据采集过程中的偏差问题,以及AI“审美逻辑”流程化和过分追求准确结果等,均会导致AI模型在识别、理解与模拟人的审美时困难重重。未来,即便AI技术能够快速进步,人类也会因风险管控等原因不得不限制AI在主观能动性方面的性能。

对新安江人工养殖虹鳟性腺的自然分化进行了系统组织学研究。刚孵化出膜仔鱼的生殖嵴巳形成,原始生殖细胞成单行排列于生殖嵴上,并正在进行有丝分裂。水温10—11℃时,孵出后6—8周仔鱼的性腺出现解剖学分化。紧接着卵巢中的卵原细胞开始向初级卵母细胞过渡。精巢中的精原细胞向初级精母细胞过渡的时间比卵巢约晚2—3周。性腺的细胞学分化时间,雌雄鱼表现不一致。

Experimental and theoretical analysis of loading characteristics of electret filter media for charged particles

引用

Particuology 2024年第10期93卷 87-98页

作者： yiqi Cai Rongrong Cai Lizhi Zhang Key Laboratory of Enhanced Heat Transfer and Energy Conservation of Education Ministry School of Chemistry and Chemical EngineeringSouth China University of TechnologyGuangzhou510640China State Key Laboratory of Subtropical Building Science South China University of TechnologyGuangzhou510640China

The degradation of filtration performance in electret filter media during usage poses a significant challenge. Pre-charging of aerosols has been identified as an effective method to mitigate this issue. However, the effects of particle charging characteristics on the loading characteristics of electret filters still need a comprehensive understanding. In this study, a needle-cylinder corona charger was employed to pre-charge aerosols, and the particle charge state was determined by multiphysics simulation. The effects of particle charge polarity and charge quantity on the loading performance of the electret filter were quantitatively investigated. The results showed that the particle charge polarity had a negligible impact on the loading performance under the condition of the equivalent particle charge quantity. In addition, the charged particles effectively improved the efficiency degradation during the loading process of electret media, with higher charge quantities resulting in more pronounced improvements. The electrostatic attenuation factor showed a negative exponential correlation with the particle charge quantity. This was attributed to the uneven particle deposition on fiber surface due to the attraction of charged particles by the opposite charges on the electret fibers, which alleviated the effect of electrostatic shielding.
