建筑物尾流区气流与污染物扩散的数值计算

采用了细网格非静力能量闭合边界层模式和随机游动模拟方法建立了一套分析建筑物尾流流场和污染物扩散的数值模拟系统．作为应用研究的例子，在对某城市地下交通隧道排废气的风井塔尾流区流场和浓度场进行风洞流体物理实验的基础上，利用所建的模拟系统对风井塔尾流区气流和污染物扩散特征进行研究．结果表明，所建的模拟系统的模拟结果与风洞试验的结果吻合较好，对一些小尺度带有明显湍流不均匀性的流场和局地空气污染物散布的情况有较好的模拟效果和良好的应用前景．

“引江济太”工程对太湖水体交换的影响研究

为了探究"引江济太"工程对太湖水体的交换范围及能力的影响，本研究耦合对流扩散及水体交换模型，依据不同流量与常规风场共设置10种工况，对太湖水体的交换区域及交换周期进行数值模拟.结果表明：（1）流量是影响水体交换率的主要因素，200m³/s下贡湾的半交换周期与常规风场联系不大，稳定在8~9d左右；（2）常规风场对局部交换区域的空间分布有着明显影响，在北风和西北风条件下，太湖水体的交换区域主要集中在东湖区，东风和东南风条件下，太湖水体的交换区域主要集中在西北湖区；（3）为降低长江水体对太湖水质的不利风险，"引江济太"工程引水时间/方案应结合太湖区域气象预报，尽量选择在以东风或者东南风为主的条件下进行引水工作.

Efficient degradation of organic pollutants by S-NaTaO3/biochar under visible light and the photocatalytic performance of a permonosulfate-based dual-effect catalytic system

Removing large concentrations of organic pollutants from water efficiently and quickly under visible light is essential to developing photocatalytic technology and improving solar energy efficiency. This study used a simple hydrothermal method to prepare a non-metallic, S-doped NaTaO₃ (S-NTO) photocatalyst, which was then loaded onto biochar (BC) to form a S-NTO/BC composite photocatalyst. After uniform loading onto BC, the S-NTO particles transformed from cubic to spherical. The photogenerated electron-hole pair recombination probability of the composite photocatalyst was significantly lower than those of the NTO particles. The light absorption range of the catalyst was effectively widened from 310 nm UV region to visible region. In addition, a dual-effect catalytic system was constructed by introducing peroxymonosulfate (PMS) into the environment of the pollution to be degraded. The Rhodamine B, Methyl Orange, Acid Orange 7, tetracycline, and ciprofloxacin degradation efficiency at 40 mg/L reached 99.6%, 99.2%, 84.5%, 67.1%, and 70.7%, respectively, after irradiation by a 40 W lamps for 90 min. The high-efficiency visible-light catalytic activity of the dual-effect catalytic system was attributed to doping with non-metallic sulfur and loading of catalysts onto BC. The development of this dual-effect catalytic system provides new ideas for quickly and efficiently solving the problem of high-concentration organic pollution in aqueous environments, rationally and fully utilizing solar energy, and expanding the application of photocatalytic technology to practice.     

Amniotic fluid fibrinolytic system in fetal neural tube defects

Second trimester amniotic fluid fibrinolytic system was examined in normal pregnancies and those complicated by anencephaly, spina bifida and fetal chromosome abnormalities. No significant difference was demonstrated between the fibrinolytic systems from normal pregnancies and those complicated by fetal chromosome abnormalities. In pregnancies complicated with anencephaly and spina bifida no significant difference was demonstrated for alpha-1-antitrypsin, alpha-1-antichymotrypsin and urokinase. Plasminogen was significantly lower (p < 0.02) and plasmin significantly higher (p < 0.001) than levels from normal amniotic fluid. Alpha-2-macroglobulin, fibrinogen, FDP-D and FDP-E were detected only in pregnancies complicated with anencephaly and spina bifida.
