本研究旨在探究乙酸改性对钢渣及其沥青混合料性能的影响,并分析其微观改性机制。通过使用不同浓度的乙酸溶液(5%,10%和15%)对钢渣进行处理,对比了改性后的钢渣、未改性钢渣以及玄武岩的宏微观特性。在微观层面,利用扫描电子显微镜(SEM)和X射线荧光光谱(XRF)技术,揭示了改性钢渣的化学成分及其微观结构的变化;而在宏观层面,重点评估了钢渣沥青混合料的路用性能和体积膨胀性。研究结果表明,乙酸改性能有效去除钢渣表面的膨胀性物质(f-CaO和f-MgO),同时生成的醋酸钙白色粉末有助于改善混合料的级配。乙酸浓度为5%和10%时,不能充分反应完钢渣表面物质。乙酸浓度为15%时,改性后钢渣与沥青之间仍保持良好的粘附性,钢渣沥青混合料的体积膨胀率降至0.3%,相比于未改性钢渣高温、水稳及疲劳特性得到了显著提升。

The leading cause of visual impairment was cataract of 55.0% (101/187) blindness and of 50.2% (116/231) low vision, followed by fundus lesions of 22.9% blindness and 23.8% low vision, while only a low prevalence of glaucoma of 9.6% blindness and 1.7% low vision was observed. The analysis of 2 219 eyes showed that the most common external eye disease was pterygium (27.2%) in ***: The high prevalence of blindness and low vision in the Tibetan population at high altitude is a serious public health issue. There is a need to establish and maintain an appropriate effective eye care program in Tibet.

Open-graded friction course(OGFC) is applied to pavement surfaces to increase driving safety under wet conditions, and recently, to reduce tire/pavement noise. The durability of OGFC, however, has been a concern since conventional OGFC mixes last typically less than ten years before major maintenance or rehabilitation is needed. This work investigates a new open-graded asphalt mixture that uses epoxy asphalt as binder to improve mix durability. One type of epoxy asphalt that has been successfully applied to dense-graded asphalt concrete for bridge deck paving was selected. A procedure of compacting the mix into slab specimens was developed and a series of laboratory tests were conducted to evaluate the performance of the new mix, including Cantabro loss, permeability, friction, shear strength, and wheel rutting tests. Results show superior overall performance of the open-graded epoxy asphalt mix compared to conventional open-graded asphalt mix. There are also preliminary indications that the OGFC mix with 4.75-mm NMAS gradation can improve the resistance performance to raveling, while the OGFC mix with 9.5-mm NMAS gradation can improve the performance of surface friction at a high slip speed.

研究旨在测定西藏改良奶牛(荷斯坦奶牛♂×西藏牛♀)在低氧环境下的血液常规指标和凝血生理指标,通过定期检测生产性能测定指标(DHI)与泌乳量对西藏改良奶牛的改良效果进行评估。试验以高原低氧环境下(位于西藏山南市琼结县,海拔3 617 m)饲养的改良奶牛作为研究对象,选取从澳大利亚引进西藏的荷斯坦奶牛和西藏牛(西藏本地黄牛)作为对照,测定血液常规指标、凝血指标、DHI指标和头胎次泌乳产量。结果显示,经过长期的低氧环境适应后,西藏改良奶牛的血液生理指标和DHI指标等均发生了明显的变化,主要表现为血红蛋白浓度(HGB)、红细胞比容(HCT)、平均红细胞体积(MCV)显著高于引进荷斯坦奶牛和西藏牛(P0.05),凝血功能较引进荷斯坦奶牛得到改善。与引进荷斯坦奶牛相比,西藏改良奶牛乳脂率、乳蛋白率、乳糖等指标显著升高(P<0.05),体细胞数显著降低(P<0.05)。研究表明,西藏改良奶牛已具备了一定的低氧适应能力,比引进荷斯坦奶牛更能适应低氧环境,相较西藏牛和引进荷斯坦奶牛,西藏改良奶牛的生产性能得到优化和改善。
