【 摘 要 】

by the investigation of Chromium (Cr) dataset in waters around the bay mouth in Jiaozhou Bay in1983, calculated were the absolute and relative horizontal loss, and vertical accumulation and dilution amounts, and identified the spatial motion processes. Results showed that the absolute and relative horizontal losses were 0.12-0.59μg L-1 and 7.69-93.93%, respectively. The absolute and relative vertical accumulation amounts were 0.14-0.86μg L-1and 8.86-86.86%, while the absolute and relative vertical dilution amounts were 0.02-0.62μg L-1and 2.17-80.00%, respectively. Cr was mainly sourced from river runoff and marine current, and was moving to the bay mouth from the inside of the bay mouth and the outside of the bay mouth, respectively. There were high sedimentation processes, and were forming high accumulation processes in bottom waters. Therefore, there were diffusion and sedimentation processes in waters in the inside of the bay mouth and the outside of the bay mouth. This spatial motion process, was named as Yang's Phenomenon.
