Fine flow structures and velocity field structures were obtained via NPLS （nanoparticle-tracer planar laser scattering） and PIV （particle image velocimetry） techniques, time- averaged flow structures were researched, and spatiotemporal evolutions of transient flow structures were analyzed. The flow visualization results indicated that when the ramp angles were 25~, a typical separation occurred in the laminar flow, some typical flow structures such as shock induced by the boundary layer, separation shock, reversed flow and reattachment shock were visible clearly. While a certain extent separation occurred in turbulent flow, the separation region was much smaller. When the ramp angles were 28~, laminar flow separated further, and the separation region expanded evidently, flow structures in the separation region were complex. While a typical separation occurred in turbulent flow, reversed flow structures were significant, flow structures in the separation region were relatively simple. The experimental results of velocity field were corresponding to flow visualization, and the velocity field structures of both compression ramp flows agreed with the flow structures well. There were three layered structures in the U component velocity, and the V component velocity appeared like an oblique ＂v＂. Some differences between these two compression ramp flows can be observed in the velocity profiles of the shear layer and the shearing intensity.展开更多

Furthermore, the effect of forest canopy may be changed by complex topography. In this paper, we measured and simulated the incoming longwave radiation to snow beneath forest at different canopy openness in the west Tianshan Mountains, China(43°16'N, 84°24'E) during spring 2013. A sensitivity study was conducted to explore the way that terrain influenced the incoming longwave radiation to snow beneath forest canopies. In the simulation model, measurement datasets, including air temperature, incoming shortwave radiation above canopy, and longwave radiation enhanced by adjacent terrain, were applied to calculate the incoming longwave radiation to snow beneath forest canopy. The simulation results were consistent with the measurements on hourly scale and daily scale. The effect of longwave radiation enhanced by terrain was important than that of shortwave radiation above forest canopy with different openness except the 20% canopy openness. The longwave radiation enhanced due to adjacent terrain increases with the slope increase and temperature rise. When air temperature(or slope) is relatively low, thelongwave radiation enhanced by adjacent terrain is not sensitive to slope(or air temperature), but the sensitivity increases with the decrease of snow cover area on sunny slope. The effect of longwave radiation is especially sensitive when the snow cover on sunny slope melts completely. The effect of incoming shortwave radiation reflected by adjacent terrain on incoming longwave radiation to snow beneath forest canopies is more slight than that of the enhanced longwave radiation.展开更多

The research identifies key obstacles to income expansion, including an undiversified industrial structure, insufficient human capital, and a lack of robust social protection. These call for systemic solutions featuring institutional innovation, resource consolidation, and capability enhancement. Building on Zhejiang's experience as a common prosperity demonstration zone, the article constructs an integrated framework centered on four pillars: industrial empowerment, education upgrading, social security reinforcement, and digital coordination. It further offers concrete policy proposals involving the cultivation of localized industries, vocational skill training, enhanced safety nets, and the adoption of digital tools. The study thus offers both theoretical insights and practical paradigms for tackling the challenge of raising incomes in low-income rural areas.展开更多

文摘Objective:To explore the associations between income levels,employment risk,lifestyles,occupational stress,and male fertility.Methods:This cross-sectional study analyzed 294 men seeking fertility treatment at fertility clinics in Terengganu,Pahang,and Kuala Lumpur from November 2021 to June 2023.Data were collected through structured questionnaires covering income levels,lifestyles,employment risks,occupational stress,and semen quality.Multinomial logistic regression was employed to assess predictors of semen quality,with crude and adjusted odds ratios(OR)reported.Results:The lower-income group exhibited higher odds of having abnormal semen quality compared to normal semen quality.Specifically,these participants were more likely to experience azoospermia[crude OR 6.68,95%confidence interval(CI)1.84-52.63;adjusted OR 6.26,95%CI 1.76-51.38],indicating a link between low income and infertility issues.Lifestyle factors did not show significant associations with semen abnormalities after adjustment.High employment risks had significant associations with oligozoospermia after adjustment(crude OR 5.50,95%CI 2.14-14.11;adjusted OR 5.15,95%CI 1.93-13.71),while high occupational stress was linked to asthenozoospermia(crude OR 2.26,95%CI 1.09-4.68;adjusted OR 2.25,95%CI 1.07-4.69).Conclusions:The findings underscore the influence of socioeconomic and occupational factors on male fertility,showing associations between lower income levels,high-risk occupations,and semen abnormalities.In contrast,lifestyle factors did not show significant associations with semen abnormalities after adjustment.Nevertheless,the current findings should be further confirmed through more extensive studies focusing on abnormal semen and lifestyle factors.
文摘In the heart of Antananarivo,Madagascar’s sundrenched capital,Joseph Andrinirina flashes a nervous smile as he inspects a faulty car engine at the start of another day of work at his garage.“Since I started this business six months ago,I enjoy being my own boss.I now earn a steady income,support my family,and provide jobs for others,”he told ChinAfrica.
文摘This review takes stock of China’s Double Reduction.In the short run,it lowered visible burden and pushed demand from subject tutoring toward on-campus and non-subject services.But with high-stakes selection unchanged,demand reappears as small-group/one-to-one provision,advantaging families with high socioeconomic status and strong schools.Lasting relief will require tighter oversight and admissions reform with targeted,well-funded in-school support.
文摘Nujiang farmers use the innovative dryland rice cultivation technology developed by a Chinese expert team to grow yields and income.As April ushers in spring,mist clings to the deep valleys of the Nujiang Grand Canyon in Southwest China’s Yunnan Province.High on a mountainside in Ziji Village,Daxingdi Town,Lushui City,Nujiang Lisu Autonomous Prefecture,at an altitude exceeding 1,300 metres,62-year-old Lisu villager Cha Wenxing is planting rice.These demonstration plots,cultivating high-quality upland rice,seem to float amongst the clouds.
文摘China’s consumer market showed gradual recovery from the COVID-19 pandemic in 2024,but it has yet to fully rebound to pre-pandemic levels.Official data from the National Bureau of Statistics showed that total retail sales rose by 5.3 percent year-on-year in 2024,a modest improvement from 2023 but still lagging behind the 8 percent average annual growth seen before the pandemic.Experts highlighted lingering challenges:weak consumer confidence,slowing income growth,and regional and urbanrural disparities in spending.
文摘This study examines the sustainability of China's pension funds in a context of negative population growth,analyzing how demographic shifts,economic fluctuations,and institutional flaws impact fund operations.The research reveals that declining working-age populations and accelerating aging are causing imbalances in fund revenues and expenditures.Slower economic growth and inflation further erode contribution capacity and investment returns,while the drawbacks of the Pay-as-you-go system and provincial-level pooling models exacerbate regional risks.Pension funds face multiple challenges including revenue-expenditure imbalances,investment volatility,systemic design flaws,and population mobility-induced risks.The study proposes comprehensive optimization strategies encompassing population structure improvement,diversified funding channels,expenditure control,enhanced investment management,and institutional reforms.These measures aim to provide theoretical and practical references for addressing the sustainability challenges of pension funds under negative population growth.
