Experimental Study on Tip-Induced Electrospinning

针尖诱导电纺技术(TIE)利用针尖阵列插入聚合物溶液表面后快速抽离,由于高压强电场和黏性力作用在液面抽离处诱导形成泰勒锥,进而在收集板上得到大量纳米纤维,实现纳米纤维的批量制造.实验结果表明在不同电极间距下,电纺阈值电压随着溶液浓度的增加而增大.当工作电压为63 kV,溶液槽尺寸为142 MMx50 MM时,电纺聚氧化乙烯(PEO)溶液的纤维产量达1.961 2 g/H.当工作电压从45 kV增加到63 kV时,纤维沉积均匀性变化范围为31.08%~43.23%.Tip-induced electrospinning(TIE) is demonstrated to produce nanofibers with high throughput.Probe array was plunged into the plane polymer solution and then withdrawn quickly,and due to the effects of viscous force and the electric force,Taylor cones were generated from the position where the probes left,and then mass nanofibers were obtained on the collector.The experimental results show that the threshold voltage under different electrode distances increases with the increase of the concentration,and the mean throughput of polyethylene oxide(PEO) nanofibers is up to 1.961 2 g / h when the solution tank size is 142 mm × 50 mm and the applied voltage is 63 kV.And the maximum deposition error of nanofibers is within the range of 31.08% —43.23% on the condition that the applied voltage changes from 45 kV to 63 kV.国家自然科学基金重点资助项目(51035002); 国家自然科学基金资助项目(51205334); 福建省自然科学基金资助项目(2011J05139

基于可见光与近红外遥感反射率关系的藻华水体识别模式

极轨气象卫星AVHRR红光波段(波段1,波长580~680nm)和近红外波段(波段2,波长720~1100nm)的水体遥感反射率关系函数Rrs(2)-1=α0Rrs(1)-1+g-1(1?α0)中,参数α0=(bb(1)/bb(2))(a(2)/a(1))对叶绿素浓度敏感且相对独立于浊度,以1.6<α0<5.6和0.01<Rrs(2)/g<0.2为判据,可以实现叶绿素浓度为64~256μg/L的近海藻华水体识别.在2003年6月闽江口藻华水体的AVHRR遥感信息识别基础上,进行了该识别模式与传统的单波段模式,以及与比值法、NDVI法、差值法等双波段模式的比较,建议将该识别模式发展为近海藻华水体遥感的普适模式

Investigation on the iodine status among the population in rural and urban areas of Xiamen in 2013

目的了解碘盐新标准实施后农村和城市人群的碘营养现况,为有效落实科学补碘防控策略提供依据。方法在农村和城市调查点各抽取1个镇的1个村,在每个村采集自来水厂出厂水和末梢水各2份;抽取30户以上居民,采集各户家庭食用盐,用3日称量法测算各户居民人均食盐摄入量;抽取18-45岁成人50名以上,采集尿样。在抽中的镇随机选择8-10岁儿童(男女各半)、孕妇和哺乳期妇女各50名以上,采集尿样。测定盐碘、尿碘和水碘含量。结果农村和城市自来水末梢水水碘含量均值分别为4.5μg/L和6.0μg/L;居民人均每日食用盐摄入量中位数分别为7.0和5.6g;8~10岁儿童尿碘中位数分别为152.0和181.2μg/L;哺乳妇尿碘中位数分别为108.3和107.7μg/L;18-45岁成人尿碘中位数分别为121.1和147.4μg/L;孕妇尿碘中位数分别为116.0和112.2μg/L,尿碘含量低于150μg/L的比例分别达67.9%和64%;除农村人均每日食用盐摄入量高于城市,农村18-45岁成人尿碘水平低于城市外,其他指标农村和城市间差异无显著性。结论厦门市仍是缺碘地区,在现有碘盐标准下,8-10岁儿童、18-45岁成人、哺乳期妇女的碘营养处于适宜水平,但孕妇的碘营养不足,要开展针对孕期人群的碘营养监测和指导,杜绝碘缺乏所造成的危害。Objective To gain knowledge of the iodine status among the population in rural and urban areas after the implement of new standard for edible salt and to provide scientific evidence for the initiative of the iodine supplement strategy. Method 1 village / community was selected randomly from rural and urban area as research site respectively. 2 samples of treated water and tap water were collected respectively in both sites, 30 + houses were enrolled randomly and edible salt samples were collected. 3days weighed record was employed to estimate average salt daily intake. Urine sample was collected from 50 + adults aged from 18 to 45. Identical sample was also collected from 50 + children aged from 8 to 10( same amount of subjects in both genders),pregnant women, and lactating women respectively. Iodine level of water, salt, and urine was determined by laboratory assay.Results The iodine concentration of tap water in rural and urban areas was 4. 5 μg / L and 6. 0 μg / L,respectively. The median of average iodine intake in rural and urban areas was 7. 0 g and 5. 6 g, respectively. The median in urine iodine was 152. 0 μg / L and 181. 2 μg / L,respectively. This measurement in lactating women was 108. 3 μg / L and 107. 7 μg / L,respectively. And it was121. 1 μg / L and 147. 4 μg / L in adults aged 18 to 45, respectively. As for the pregnant women, the iodine level reached 116. 0μg /L and 112. 2 μg /L,respectively. The proportion of subjects has urine iodine level less than 150 μg /L reached 67. 9 % and 64 %, respectively. The average salt intake in rural area was higher than urban significantly, and the urine iodine level in adults aged 18 to 45 from rural area was significantly lower than urban. No significance was found in other comparison. Conclusion Through our investigation,Xiamen is still an iodine deficiency area. Under the implement of new edible salt standard, the iodine status in children aged 8 to 10, adults aged 18 to 45 and lactating women was adequate, however, we found that pregnant women enrolled in our study have iodine deficiency in some degrees. Therefore the iodine surveillance and dietary guidance should be performed among pregnant women to eliminate the harm caused by iodine deficiency
