查询词典 alkali flat

Based on 3D steady and incompressible NS equation and kε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

摘 要：基于三维、不可压、定常 N S 方程和 k ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。

With Yangtze delta tidal flat as an example, through the analysis on the magnetic characteristics of tidal flat sediment and the study on the space distribution of heavy metal elements, this thesis discussed the impact to Shanghai sea bank brought by heavy intensity development, and the interrelation between sediment power effect and heavy metal pollution space distribution. Utilizing the advantage of artificial intelligence neural network, in conjunction with environmental chemical analysis, from the angle of view of sediment magnetic characteristics, it analyzed the connection mechanism between magnetic mines and heavy metal element within tidal sediments, and built a quantitative magnetical diagnosis model, in attempt to calculating the tidal heavy metal pollution status from the magnetic measurement data of sediments and assess it's impact to the environment.
