查询词典 hydrodynamic

For the floating body with complex bow and stern, the molded line reconstruction method is adopted to generate the section lines on the bow and on the stern which are necessary to construct the wetted surface, and it can raise efficiency greatly that the intersection lines of intersection structures are obtained by the way of combining modeling tool and NURBS technology; then the patch representation method is adopted in generating the mesh of wetted surface and interior free surface, and the velocity potentials on them are expressed separately, on basis of which the irregular frequency effect is dealt with in the calculation of hydrodynamic coefficients.

After analyzing the hydrodynamic condition and the variations of the water environment factors over the past 20 years(1983-2003) of Tieshangang bay ,we tried to find out the relationship between the self-purifying ability and the environment factors of Tieshangang Bay.

通过对铁山港湾水动力条件及20a(1983~2003年)来水环境因子变化状况的分析，探讨了该湾水体自净能力及其与环境因子之间的关系，结果表明：该湾具有较强的水体自净能力，但其物理净化能力是以潮流的水动力作用影响为主，迳流影响较小，与北海湾和钦州湾有明显差别；其化学净化能力主要体现在溶解氧的含量水平、有机污染物的氧化分解能力、营养盐的形态转化及消减程度上；其生物净化能力则体现在微生物及浮游动植物对有机物的直接降解及间接贡献上，具有贫营养区的水体自净特点。

Be practical and innovative, our team group work hard to complete the contents of the National Natural Science Foundation Project:"Study of the hydrodynamic behaviors of deep water sea cages". According to the development of the sea cage industry in domestic, two main widely concerning topics were added to our research program. They are the study of Sea station and Quasi-sea station cages. The workload and working strength increased dominately in our research. Delightful results were achieved with 26 science papers been proposed, in which 16 papers have been published or accepted by all kinds of journals or conferences.
