利用最新研制的测温链浮标，根据1994年6－8月在辽宁省长海县海鲜岛扇贝养殖区现场连续观测的水温实测数据，分析该区域水温连续变化特征。分析结果表明：在0－10m范围内，水温存在着极为频繁的急剧变化，而且水温的连续变化与潮位的变化基本相同。通过时间序列频谱分析可以看出，水温波动存在着明显的潮周期特征，并且水温剧烈波动的时间与扇贝出现大量死亡的时间相吻合.
Based on the measured data of water temperature continuously observed in the scallop aquaculture area of Seafood Island in Changhai County of Liaoning Province from June to August in 1994, the continuous variation of water temperature in this area was analyzed. The analysis results show that there is a very frequent and drastic change of water temperature in the range of 0-10m, and the continuous change of water temperature is basically the same as the change of tide level. From time series analysis, it can be seen that there is obvious tidal cycle characteristics of water temperature fluctuation, and the time of the water temperature fluctuation agrees well with the time when a large number of deaths occur in the scallops.
