摘要
用带电子探针的扫描电子显微镜分析和测定了长江口悬浮颗粒样品,在不同盐度的试样中,首次发现了大小、形状,组成各不相同的有机絮凝体.作者根据长江口的物理化学环境和悬浮颗粒的性质,探讨了有机絮凝体的形成机理,认为二步桥联模式能比较园满地解释长江口悬浮颗粒有机絮凝体的形成.
Samples of suspended particles, collected in Jul.86 and Sep.88 in the Changjiang river mouth, were analyzed by the SEM with electronic probe.The organic floccus were observed in suspended particles which are made of mineral partiles, organic matter and diatomaceous remains.A bridging model of two-step was used for interpratation of organic fiocculation.
