It was more efficient to combine the sediment with the Elodea nuttalli.

当系统中同时有底泥和沉水植物时，水体中的MC的去除速率更快，效果更好。

In order to investigate the relationship between ammonia in the sediment and the physiological and biochemical characteristics of macrophytes, Vallisneria natans L and Elodea nuttallii were planted in the sediments of seven different concentrations of ammonia.

In this thesis, the mathematics model was used to simulatc the alage growth in Lake Taihu; An enzyme-linked immunosorbent assay was used to monitor the spatial and temporal distribution in 2001; The microcystis spp was culturede with scendesmus obliqaus to study the toxin secrete mechanism of the MC from the population competition; The degradation of the MC by the sediment collected from Lake Taihu and one of the submerged mcrophyte Elodea nuttalli were discussed.

本文采用数学模型的方法模拟了太湖藻类的生长情况；应用酶联免疫吸附法监测了2001年MC的时空分布情况；在实验室内进行藻类培养，从种群竞争的角度初步探讨了MC的产毒机理以及太湖底泥和沉水植物对MC的自然降解作用等。

选用7种洗脱液对海洋沉积物中的病毒进行洗脱回收比较实验，结果表明：pH9。

Grain size trends show sediment transport towards the central sandbank within the embayment and the seaward end of the deep channel at the entrance. Such patterns are highly consistent with the characteristics of current velocities and geomorphology; they are also in good agreement with heavy mineral movement and spatial distribution patterns of calcareous nannofossils.

沉积物粒径趋势结果显示，胶州湾内的大型垄脊和口门延伸至外海的深槽尾部是两个主要的沉积物汇聚区，这不仅与地貌及水动力相吻合，还与根据重矿物扩散趋势一致；与颗石藻化石空间分布型式亦有一定的相关性。

The nearby beaches may supply sediment for the embayment during storm surges, by causing bed-load and suspended-load transport of the beach material towards deeper waters.

胶州湾沙滩供沙的主要机制是通过风暴潮期间强烈的动力作用，使沙滩沉积物以悬移质、底移质形式向深水区扩散或搬运。
