灰冰

pH值没有发生恶化，保持在75左右.因此，离心转速是渤海灰白冰离心脱盐过程中的主要控制性因子之一。

PH value was not deteriorative after desalination and it maintained about 7.5 . Therefore centrifugal rotational speed is one of major controlling parameters in the centrifugal desalting process of gray-white ice in the Bohai Sea .

离心转速对渤海灰白冰脱盐作用的实验研究

Testing study on desalination role of the gray-white ice in the Bohai Sea by the centrifugal rotational speed

通过实验室离心实验，研究了离心转速对渤海灰白冰脱盐、脱盐效果以及主要超标水质参数的影响。

Effect of centrifugal rotational speed on desalination and factors exceeded quality standard of gray-white ice in the Bohai Sea were studied by centrifugal experiments at the laboratory .

渤海灰白冰经过实验室离心脱盐后，全盐量等各项水质指标均可达到工农业生产和人们生活用水的指标要求。

After gray-white ice in the Bohai Sea were desalted , such quality factors as salinity of desalted ice fulfil the needs of water for the industry and agriculture production and the people 's living .
