Sun, C.; Ma, F.; Zhou, X., and Ning, L., 2015. Research and the establishment of the Bohai Sea separation model based on the model difference method. 0749-0208.With the development of marine surveying technology, there is an urgent need for solving the discontinuity problem of the depth datum. In this paper the difference model method based on the relationship between the mean sea level and the theoretical depth datum has been approached. Taking Bohai as the study area the deviation model has been built and its accuracy has been analyzed. ADDITIONAL INDEX WORDS:Seamless vertical datum, depth datum, mean sea surface, model difference method, separation model.

Domestic and foreign scholars have researched traffic flow forecasting and established mature systems; however, these systems are mainly based on normal weather. The influence of weather on traffic flow forecasting is rarely considered in existing studies. Therefore, the correlation between meteorology and traffic flow is analyzed, and an attention mechanism is introduced to improve the ability of the model to extract characteristics of time series data. The results show that the model proposed in this paper is better than other models and the traffic flow forecast using meteorological data is more accurate when an attention mechanism is added.
