Based on this method,the measured data are sorted out and analyzed,the measures and results of dam concrete temperature control in construction period are evaluated,and feedback calculation of some thermodynamic parameters is conducted,which is of universal significance to the sort-out and analysis of measured temperature data of hydraulic concrete.

Aiming at the problem that the actually measured data for radio wave tunnels perspective method are not full and the inverse equation groups are undetermined, the image of geologic abnormal body was reconstructed by using tomography method.

Based on the basic principles of BP artificial neural network model and the fundamental law of water and sediment yield in a river basin,a BP artificial neural network model is developed by using observed data,with rainfall conditions serving as affecting factors.

In order to study the performance of CFRD, regression analysis and inverse analysis are adopted to investigate the observed data of displacement of the rockfill dam under and after construction.

Based on the diurnal consecutively observed data in the offshore area of Jiaonan in 2005, the paper tries to make a preliminary analysis of the specificity of ocean currents, tidal current property and residual current property in the area in observing dates.

The comparisons and summarizations of the measured data are also carried out.

On the foundation of collecting a great deal measured data of winds and waves, and with the result of numerical simulation of large-scale wave, the second chapter does statistical analysis systematically b.

The long series of measured data of silt in the key stations in the Pearl River have been analyzed primarily in the aspects of the main silt sources,silt yearly variation,and silt annual variation as well as the sediment evolutions in major river courses.

In previous studies, few oceanographers focus on the induction of long-term observation data, while most meteorologists focus on SST, based on reanalysis data of lower resolution.
