time-distance graph

Based on large quantities of projects and experiences, the paper discusses the application of fast static position measurement in GPS control network arrangement from the angle of observation time and network graph.

通过大量实例和作者的实践，从观测时段、网图的布设方式等方面论证了快速静态定位测量在布设GPS控制网中的应用。

The author mainly developed the user interface module of extracting result data, editing result file and drawing time sequence graph and computing area of triangle and so on.

对GPS数据解算结果的后处理部分，作者主要实现了界面化数据提取，解算结果文件的编辑，利用GMT绘图软件绘制时间序列图和计算三角形面积等功能。

Our analysis indicates that multiresolution analysis has the disadvantage of miss some scatterers, especially for relative regular scattering, however, using the time frequency graph of continuous wavelet transform can obtain the better result.

分析结果表明，对规则性较强的散射体用多分辨分析容易产生漏检，而利用连续小波变换时频图则可以得到较好的效果。

When a "hidden layer" exists, two major errors may by made in interpreting the time-distance graph, because the "hidden layer" can't produce the shallow first arrivals of refracted waves.

隐蔽层用浅层初至波记录不到，而有隐蔽层存在时，在折射解释中常常产生两种误差。

Analysis of potential first-order differential 、 microseismic events B value and combined with time process graph can realize the short and mid microseismic events forecast.

结合时间进程图、微震事件b值和体变势一阶差分的分析，可以实现短、中期微震大事件的预报预测。

To read a line graph, it's important to focus on the points of intersection rather than the line segments between the points, This type of graph is most commonly used to show how something changes over time.

阅读线图时应强调把重点放在交点而不是点与点之间的线段上。这种类型的图最常用来表示事物随时间发生的变化。
