The results show that GPS is an instrument for detecting atmospheric ZHD and ZWD with a detection accuracy comparable with radiosonde.
研究结果表明：GPS是一种与探空观测有可比性的大气静力延迟和湿延迟测量手段。
The ZHD and ZWD from different GPS sites exhibit their individual features that ZHD has an obvious periodic change and ZWD is related to weather.
GPS站点测得的静力延迟和湿延迟呈现出不同特征，静力延迟有明显的周期变化，湿延迟的变化与天气过程相关联。
