摘要：Taking chromium (Cr) in waters in Jiaozhou Bay in August 1981 as an example, this paper analyzed the horizontal and vertical loss processes of Cr, as well as the vertical dilution. Results showed that from waters in the outer side of the bay mouth to the bay mouth, the absolute loss amount in surface and bottom waters, the relative loss amount in surface and bottom waters were very low as 0.00 μg L−1 and 0.08 μg L−1, 0.00% and 19.51%, respectively. From waters in the bay mouth to the inner side of the bay mouth, the absolute loss amount in surface and bottom waters, the relative loss amount in surface and bottom waters, and the vertical dilution amount were very low as 0.24 μg L−1 and 0.19 μg L−1, 57.14% and 57.57%, respectively. In waters from the outer side of the bay mouth to the bay mouth, there was little settlement, yet in waters from the bay mouth to the inner side of the bay mouth, there were rapid settlement processes and the settlement amounts were more than 50%. The marine bay is playing a role of a crock, and the bay mouth is the mouth of the crock. Once the substances have been entering the crock, the settlement processes would be very rapid. This is Yang's Marine Bay Phenomenon.
