Based on physical and psychological theories of driver's dynamic vision, combined related research methods and conclusions in home and abroad, the basic modes and characteristic parameters of driver's visual behavior were discussed systemically. Several indexes were determined as basic characteristic parameters of dynamic visual search mode, including fixation duration, visual angle, visual search scope, saccade amplitude and saccade velocity.

A review of river management history in various countries is used in this thesis to discuss the future development trends of river management and the relationship between river health and river management.Based on the characterization and assessment of river health, Five components of stream condition are presented in this thesis to characterize river health: water quality, aquatic life, physical form, hydrology and streamside zone. It is obtained by comparing the methods and criteria that have been developed by others and reviewing the river assessment practices in various countries. Accounting for the features of urbanization region in plain river network, an indicator system for river health assessment which provides scores for 5 subindices and 17 indicators is established. With almost 200 stream reaches in Shanghai as objective of study and Liwa stream and Zhangjiabang Creek as case study, the application of river health assessment in the planning, baseline survey and post-project appraisal of river management is explored by collecting historical literature and field monitoring. Consequently, some suggestions to improve river management effectiveness are presented from the angle of river health.

In general, the layered feature of electrical structure is analyzed first of all for defining preliminarily whether a DES exists in the target area or not. Then the contours of resistivity in resistivity tomogram are analyzed from the deep to the shallow part. If they extend upwardly from the deeper part to shallower one and shape into the integral dislocation, great flexure or gradient zone, it would indicate there exists the DES reflecting a buried fault. At last, horizontal tracking needs to be carried out for defining the trend of the DES reflecting a buried fault.

After a further analysis based on the empirical results,a trial probe on the cognitiveprocessing mechanism of the problem representation of the word problem in two types of MLDwas made by the author.The MRD performed much poorer than the MLD only in the mostdifficult equation listing of word problem and the medium and most difficult problemrepresentation of word problem,which showed no difference in computation and comprehensionof simple meaning of the problem,but the gap between two types of MLD became wide as afunction of difficulty and cognitive loading.It indicated that the MLD only had some advantage over MRD for they used more cognitive skills to solve the problem.
