冼夫人文化在地方高校传承和发展状况研究

以"好心精神"为核心的冼夫人文化作为粤西地区的特色文化,与当代社会主义核心价值观相契合。它对大学生进行爱国主义教育、提高人文素质、树立正确的价值观方面有重要的引导作用。以粤西4所高校为例,通过发放问卷的形式对冼夫人文化在高校大学生中的影响进行调查,指出了冼夫人文化在高校传承中存在的问题,并深入了分析在高校思想政治教育工作中如何融入冼夫人文化。     

碳化硅陶瓷膜管对PM_(2.5)捕集性能的实验研究

PM2.5因其粒径小、吸附能力强、输送距离远、环境危害大,同时捕集困难而成为世界各国共同关注的大气环境问题。以涂氧化铝膜的碳化硅陶瓷膜管(孔隙率28.16%,平均孔径20μm,过滤面积0.28 m2)为过滤元件,搭建了PM2.5捕集的实验装置,对膜管的过滤时间、通量与阻力降的关系以及捕集效率与时间的关系和膜污染控制方面进行了研究。结果表明:随过滤时间增加,通量逐渐减小,阻力降逐渐增大,捕集效率逐渐增大,对PM2.5捕集效率高达99.9%;对膜污染控制参数优化后反吹压强选定为0.8 MPa,反吹间隔时间为10 min,反吹时间为14 s。     

Evaluating losses in ecosystem services in nature reserves in Sichuan,China

Nature reserves have developed rapidly over the decades in China and play a significant role in the function of ecosystem services. The function of ecosystem services in nature reserves, however, has tended to decline in recent years due to natural hazards and human activities. Based on land use, the variation of ecosystem services value (ESV) during 2000–2010 in national nature reserves in Sichuan was evaluated. We analyzed the comprehensive effects of natural disasters and human activities on the decline of ESVs. Total ESV in the national nature reserves in Sichuan was approximately 2741.35 million US$ in 2000, 2616.81 million US$ in 2005, and 2499.06 million US$ in 2010, representing a decrease of 242.29 million US$, or 8.84%, in the decade. Forestland, grassland, wetland, and water bodies played vital roles in the function of ecosystem services, with an aggregated ESV of 99% of the total. The largest proportion of the total ESV was the protection of biodiversity at 48.6%. ESV of all land use types and single ecosystem services continued to decline during 2000–2010. A mechanism of adaptable risk prevention should be established, and unreasonable human activities should be avoided to protect ecosystems and to improve the functions of ecosystem services.     

Experimental study on the feasibility of explosion suppression by vacuum chambers

In view of the invalidity of suppression and isolation apparatus for gas explosion, a closed vacuum chamber structure for explosion suppression with a fragile plane was designed on the base of the suction of vacuum. Using methane as combustible gas, a series of experiments on gas explosion were carried out to check the feasibility of the vacuum chamber suppressing explosion by changing methane concentration and geometric structure of the vacuum chamber. When the vacuum chamber was not connected to the tunnel, detonation would happen in the tunnel at methane volume fraction from 9.3% to 11.5%, with flame propagation velocity exceeding 2000 m/s, maximum peak value overpressure reaching 0.7 MPa, and specific impulse of shock wave running up to 20 kPa s. When the vacuum chamber with 5/34 of the tunnel volume was connected to the flank of the tunnel, gas explosion of the same concentration would greatly weaken with flame propagation velocity declining to about 200 m/s, the quenching distance decreasing to 3/4 of the tunnel length, maximum peak value overpressure running down to 0.1-0.15 MPa and specific impulse of shock wave below 0.9 kPa s. The closer the position accessed to the ignition end, the greater explosion intensity weakened. There was no significant difference between larger section and smaller vacuum chambers in degree of maximum peak value overpressure and specific impulse declining, except that quenching fire effect of the former was superior to the latter. The distance of fire quenching could be improved by increasing the number of the vacuum chambers.
