Studies on the Mechanism of Occurrence and the Diffusion of Oxygenless Water Occurring by Organic Bottom Deposits, in a Fish Culture Sea Area

我们清楚地了解了无氧水的外观和差异的机理，在鱼文化的海内区，我们对海区的水质量和潮汐流进行了现场调查，对氧需求和底部沉积物的特定特征进行了实验，通过温度的变化，也在他们之间寻找关系。（1）我们认为在底部沉积物Eh和氧需求中，每个响应温度通过实验对氧需求的底部沉积物之间的关系。此外，我们在氧化速度和Eh的上升速率上被采纳。（2）我们解释了融合值减少之间的关系（最低价值）和无氧条件下的底部沉积温度，而且也对Eh.3）的下落速度进行了提炼，我们根据不同的有机政策确定了Eh与底部沉积物之间的关系。我们解释了在海底沉积物和TN.5之间的最低Eh值）我们在海洋区域的海底沉积物和海底沉积物之间的关系.6）我们确定了在鱼类文化区域的底部沉积物之间的关系.7）我们调查了在鱼类文化设施下的潮汐当前速度下的关系，根据每个潮汐范围的垂直分布的差异，以及Eh和潮汐当前条件之间的关系. 8）我们在入口口测量了垂直分布的垂直分布。我们研究了鱼类文化区域潮汐流的差异。在融合中，我们提出了一个模拟模型，用于测量海底沉积物的E和海洋水的密度，并通过使用温度、DO和潮汐速度作为参数来测量海水的密度。

We made it clear about mechanism of appearance and diffusion of oxygenless water, in the fish culture sea inlet area.We conducted a spot investigation of the water quality and tidal current in the sea area, experimented on the oxygen demand and the specific characteristic of the bottom deposits, by the temperature change of it and also searched for the relationship between them.That is to say,1) We considered the relationship between bottom deposits Eh and oxygen demand in each response temperature by experimenting on the oxygen demand of the bottom deposits. Also we elucidated on the oxidation speed and the rate of climb of Eh.2) We explained the relationship between the reduction of convergance value (lowest value) and the temperature of bottom deposits under oxygenless conditions, and also elucidated on the dropping speed of the Eh.3) We clarified the relationship between Eh of the bottom deposits and the temparature occurring by the different organic pollution.4) We explained the relationship between the lowest Eh value of bottom deposits and TN.5) We elucidated on the relationship between the bottom sea DO and the Eh of bottom deposits in the fish culture sea area.6) We clarified the relationship between Eh of the bottom deposits in the fish culture area.7) We investigated the tidal current speed under the fish culture facilities, considered the difference of the vertical distributions by each tidal range, and the relationship between the condition of the Eh and tidal current.8) We measured the vertical distributions of the tidal current at the mouth of the inlet. And we investigated the distibution difference of the tidal current in the fish culture area.In conclusion, we have proposed a simulation model for measuring Eh of the bottom deposits and DO density of the sea water by using the temperature, DO and tidal・current speed as parameters.
