基于Matlab GUI的全球重力固体潮可视化实现

Visualization of gravity earth tides based on Matlab GUI

阐明重力固体潮理论值计算原理,利用改进的计算新方法编写Matlab计算程序,采用Matlab中的GUI平台,对全球重力固体潮进行可视化实现,直观观察固体潮在地面的时空变化规律。通过输入时间和经纬度,确定采样间隔(秒采样、分钟采样、时采样),实现以下功能:(1)以图像和Excel形式,输出某一地区的重力固体潮理论值;(2)仿真未来24小时全球重力固体潮。

We introduced the principle of calculating the theoretical value of gravity solid tide, and then used a new and improved method to reprogram the calculating program in Matlab. We use the GUI platform of Matlab to visualize it. By entering the time and latitude and longitude and determining the sampling interval(respectively, seconds sampling, minutes sampling, hour sampling), it can implement two functions as follows: one is the output of a region of gravity solid tide with an image and an Excel form, the other the simulation of the next 24 hours of global gravity solid tide. So it can be used to observe the temporal and spatial variation of the solid tide on the ground and provide a good platform for the study of solid tide.
