dc.description.abstract运用增强型混合纤维素(CN CA)膜、聚碳酸酯膜和聚丙烯滤芯过滤3种不同的方法采集、研究厦门湾水体中悬浮颗粒物(SPM)及其U、Th同位素的粒径谱.发现3种方法所得SPM总浓度和U、Th各同位素的总比活度具有很好的一致性,但粒级分布存在差异.SPM的浓度随粒径的增大而增加,并且SPM的粒径谱控制着颗粒活性很强的4种钍同位素的粒径谱.对于所研究的3种方法,采用聚碳酸脂膜过滤是研究沿岸海域SPM及颗粒活性核素粒级分布比较理想的方法. 【英文摘要】 Size spectra of suspended particulate matter (SPM) and U、Thisotopes in the sea water of Xiamen Bay were studied using three filtering ways via CN-CA membrane filter, polycarbonate membrane filter and polypropylene cartridge. The consistents of total concentration of SPM and also total specific activities of U、Th isotopes amony three ways were observed, but different size-fractionated distribution was occurred. The concentration of SPM increased with increasing sizeand the size spectra of SPM regulated the s...zh_CN
