1活性氧化铝除氟研究显示文摘针对目前活性氧化铝饮水除氟中存在的问题,进行了生产性试验研究,通过采用原水投加CO_2气体降低pH值、小颗粒活性氧化铝、大流量短历时的NaOH循环再生法等新技术,提高了活性氧化铝的吸附容量和处理水的能力,克服滤料板结和假疲劳,除氟效果稳定可靠,水质好,再生时间短,用药省,降低了基建投资和运转费用。North China Municipal Engineering Design Institute A full-scale plant was set up for studying the existing problems on the fluoride removal from drinking water by activated alumina. Some new methods was adopted,such as the addition of CO2to reduce water pH value,the use of small-sized activated alumina,and the employment of a cyclic regeneration at large flow rate with NaOH as regenerant,which result in the improvement of adsorption capacity of activated alumina and treatment capacity, the elimination of the hardening of filtration materials and false fatigue,stable and reliable effectiveness,good quality in water,short regeneration time,small consumption of regenerant. And then the capital and openational costs were reduced. 1989中国给水排水1989,5,3:5

5The Cosmic Dust in Suzhou Granite:Ablated Products of a Cometary ExplosionHu Zhong-wei,Wang Er-kang,Wan Yu-qiuDepartement of Astronomy,Nanjing University,Nanjing 210093,China Department of Earth Sdence,Nanjing University,Nanjing 210093,China Cosmic dust has been collected in large number from deap-sea sediments,Greenland ice deposits,the stratosphere and space,of cosmic dust,some are the unmelted micrometeorite,and most are the ablated products of me-teoroids in the atmosphere.Cosmic dusts were recovered from two sites of the 1908 Tunguska explosion and the 1965 Revelstoks explosion Since 1987,a large number of microspherules have been extracted from Suzhou granite of China Their suface and section structures,mineral and chemical composition show that these microspherules are of the ablated cosmic dust.The microspherules occurred in the inner contact complex intrusion.It suggests that the microspherules may be products of the same event and were aggergated in some strata and then captured by the emplacement of granitic magma.Although the microspherules are similare to other ablated cosmic dusts,there are some diferences.Our calculated results of cometary motion through the atmosphere and explosion show that the microspherules may be the ablated dust of a comet with mass above 1015g at its explosion near the ground. 1996紫金山天文台台刊1996,15,3:2
6Developments in diagnosis and treatment of paediatric septic arthritis显示文摘Acute septic arthritis in children is an orthopaedic emergency.A delay in diagnosis and inappropriate treatment can result in devastating damage to the joint with lifelong disability as a consequence.The clinical presentation can be a diagnostic challenge,especially in young children.A recent systematic review showed that joint tenderness and fever are important signals of septic arthritis.Ultrasound is helpful in detecting the presence of a joint effusion.Plain radiographs may show bone changes but magnetic resonance imaging is the most reliable imaging study for detecting concomitant osteomyelitis.The diagnosis of acute septic arthritis is highly suggestive when pus is aspirated from the joint,in case of a positive culture or a positive gram stain of the joint fluid,or if there is a white blood-cell count in the joint fluid of more than 50000/mm3.Staphylococcus aureus is the most commonly cultured organism.Recent systematic reviews have identified the most effective drainage techniques,including needle aspiration,arthroscopy and arthrotomy,depending on the affected joint.After the drainage procedure it is important to monitor the clinical and laboratory outcomes.Additional drainage procedures may be necessary in select cases.Cornelia M Donders Anne J Spaans Herbert van Wering Christiaan JA van Bergen 2022World Journal of Orthopedics2022,13,2:2
