Based on data collected at four stations in Daning River in the spring of 2004 and 2005, phytoplankton community structure, vertical distribution, abundance, biomass, C contents, diversity index, richness index and evenness index were studied. The causes of eutrophication and water blooms in Daning River were analysed and control measures were then put forward. The dominant species were Asterionella Formosa, Cryptomonas ovata, Cyclotella caspia, Stephanodiscus neoastraea in the spring of 2004 and those were Pandorina morum, Eudorina elegans, Cyclotella caspia, Cryptomonas ovata in the spring of 2005. Average cell densities, biomass, C contents in the spring of 2004 and 2005 were 171.1×10^5 cells/L, 12.2 mg/L, 1732.2g C/L and 113.1×10^5 cells/L, 10.1 mg/L, 1395.9g C/L, respectively.

Based on the present findings, it appears that all the Taiwan WAIS-Ⅲ working memory index, the single Arithmetic and the Digit Span subtests, and the span scores of the Digit Span subtest could adequately discriminate individuals without working memory impairment, but had poor sensitivity on detecting the patients who evidenced working memory impairment. Accordingly, it is suggested that clinicians should gauge the working memory index by a composite of the Arithmetic, the Digit Span, and the Letter-Number Sequencing subtests if possible. Otherwise, a caveat should be taken with care to interpret the working memory index, as estimated by a composite of the Arithmetic and the Digit Span subtests, because the chance of the increasing false negative rate becomes ineludible.

Therefore, the study is significant both theoretically and practically. As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. In this paper, the OpenGL virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the MMG mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. In the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the MMG module mathematical model and serial experimental result. After compiling the program, the calculation results are compared with the experimental data, the coherence between them validate the mathematical model.
