为防震减灾事业做好科普宣传--南京地震科学馆的建设与发展

从1989年江苏省第一届科普宣传周起,南京基准地震台都被列为宣传周期间重点对外开放单位.于是,南京地震台克服重重困难,筹建了地震科学馆.十多年来在江苏省地震局和有关单位的大力支持下,由最初腾出地震台的会议室和几间办公室发展到有530平方米的展室和多功能厅,展出内容也得到丰富.同时,地震科学馆在防震减灾宣传中取得了一定的社会效益.

Genetic amniocentesis following multifetal pregnancy reduction to twins: Assessing the risk

Fifty-three patients who elected to reduce their pregnancies to a twin gestation in our centre are known to have subsequently undergone genetic amniocentesis. Five of these patients lost their entire pregnancy following the genetic amniocentesis procedure. This is equivalent to a 9·4 per cent pregnancy loss rate for reduced twin gestations in comparison with an expected loss rate of 2 per cent for non-reduced twin gestations.     

First-trimester prenatal diagnosis in quintuplets: A practical approach using step-by-step embryo reduction

A multiple pregnancy of high rank may occur in a couple at risk for a Mendelian disorder. Prenatal diagnosis is hampered by the difficulty of (1) obtaining chorionic villi from each zygote arid (2) unequivocally relating each sample to the corresponding embryo. The calculation of the genetic risk according to the number of zygotes led us to propose a diagnostic strategy based on embryo reduction, a technique initially designed to improve the perinatal outcome of multiple pregnancies with normal embryos. We report a case in which this approach allowed rational use of first-trimester chorionic villus sampling in a quintuplet pregnancy at risk for non-ketotic hyperglycinaemia, resulting in the selective birth of unaffected twins.     

海绵铁预处理DSD酸废水的研究

用铁泥废渣制备水处理材料海绵铁,研究含碳球团直接还原的金属化率与还原时间,温度和铁泥粒度之间的关系,得到含碳球团制备海绵铁的反应参数。并对海绵铁预处理DSD酸废水的各种影响因素进行了试验研究,确定最佳试验条件;通过试验对海绵铁处理DSD酸废水的机理进行了探讨,确定它是电化学作用、电场作用、絮凝沉淀以及物理吸附等共同作用的结果。试验表明,海绵铁可作为高浓度DSD废水的预处理材料。     

微型生物与金属腐蚀的研究

主要研究了海洋微生物与金属腐蚀的相关性。通过调查、分析海洋微生物的性质,尤其是硫酸盐还原菌（ＳＲＢ）,用移植埋片法对海底沉积物中ＳＲＢ含量的分析,建立了ＳＲＢ含量与腐蚀率之间的表象关系,为海洋工程设计提供了重要数据。     

兰州市城市生活垃圾处理研究

城市生活垃圾是指在城市日常生活中或者为城市日常生活提供服务的活动中产生的固体废物以及法律、行政规定视为城市生活垃圾的固体废弃物.随着中国城市化进程的加快和人民生活水平的提高,城市生活垃圾也在以每年8%～10%的速度增长,若垃圾问题得不到妥善解决,就会制约兰州市的发展.在对兰州市城市生活垃圾处理现状及存在问题分析的基础上,根据兰州市生活垃圾的特性,提出兰州市城市生活垃圾的处理办法:兰州市城市生活垃圾应当推行分类收集制度,由目前单一的卫生填埋处理走向资源化综合处理.     

Decomplexation of Cu-1-hydroxyethylidene-1,1-diphosphonic acid by a three-dimensional electrolysis system with activated biochar as particle electrodes

The feasibility of decomplexation removal of typical contaminants in electroplating wastewater, complexed Cu(II) with 1-hydroxyethylidene-1,1-diphosphonic acid (Cu-HEDP), was first performed by a three-dimensional electric reactor with activated biochar as particle electrodes. For the case of 50 mg/L Cu-HEDP, Cu(II) removal (90.7%) and PO initial pH 7, acid-treated almond shell biochar (AASB) addition 20 g/L, and reaction time 180 min, with second-order rate constants of 1.10 × 10⁻³ and 1.94 × 10⁻⁵ min⁻¹respectively. The growing chelating effect between Cu(II) and HEDP and the comprehensive actions of adsorptive accumulation, direct and indirect oxidation given by particle electrodes accounted for the enhanced removal of Cu-HEDP, even though the mineralization of HEDP was mainly dependent on anode oxidation. The performance attenuation of AASB particle electrodes was ascribed to the excessive consumption of oxygen-containing functionalities during the reaction, especially acidic carboxylic groups and quinones on particle electrodes, which decreased from 446.74 to 291.48 µmol/g, and 377.55 to 247.71 µmol/g, respectively. Based on the determination of adsorption behavior and indirect electrochemical oxidation mediated by in situ electrogenerated H₂O₂ and reactive oxygen species (e.g., •OH), a possible removal mechanism of Cu-HEDP by three-dimensional electrolysis was further proposed.
