地转偏向力的物理实验及旋转流体定量分析

The Physical Experiments of the Coriolis Force and Quantitative Analysis of the Rotating Fluid

使用流体旋转平台模拟流体旋转与直行两种运动以及它们的合成运动。同时设计配置多个不同坐标系进行多角度流体观察与物理量测量。这些实验不仅从定性和定量两方面对属于虚拟力的地转偏向力原理进行了验证,还通过各类实验参数的调试对比与记录,扩展了旋转平台的科研功能。关于不同旋转速度`不同水深以及非均匀水深的系列实验结果均显示了地转偏向力的效应,反映了地转偏向力对实际大气及海洋系统运动特征与规律的影响。

Using the rotating table of Nanjing University of Information Science ＆ Technology,which was designed and made by a team that authors jointed, a series of physics simulations on fluid motions including rotating, straight ward, and their composition were carried out. The series of coordinate were designed for the rotating table so that the fluid observing and measurement from multi-angles can be done. The experiments showed and verified the Coriolis force which is a virtual force through quantitative and qualitative ways, and furthermore, the research function of the rotating table was developed by adjusting environmental parameters and testing influence factors in the experiments, e.g. the fluid experiments carried on by the rotating table had innovation signification. The experiments with different rotating velocities, water depths and non-uniform water depths all well showed the effect of Coriolis force, and reflected the influence of the Coriolis force on the features and rules of the atmospheric and oceanic system motions.
