This paper compares and analyzes the change trend of zenith tropospheric delay (ZTD) and integrated water vapor (IWV) at BJFS, LHAS and WUHN stations in July 2002, and puts forward a new method which can calculate directly IWV using GPS ZTD without other transformations.
比较和分析了北京、拉萨和武汉等跟踪站2002年7月的天顶对流层延迟和大气综合水汽的变化趋势,提出了无需进行其他转换利用天顶对流层延迟直接推算水汽含量的新方法,并对实测数据的计算结果进行了验证,证明了该方法的可行性。

The annual period changes of zenith tropospheric delay for two years were calculated from the observations of 9 GPS continuously operating stations in Tianjin area as well as 4 IGS reference staions,and the time-space correlations of zenith tropospheric delay at different locations were analyzed.
利用天津地区9个GPS连续观测站两年的数据,及4个IGS参考站的观测数据,计算分析了天津地区GPS连续观测站天顶对流层延迟的年周期变化,以及不同位置的GPS站天顶对流层延迟的时空相关性。
4) Zenith delay
天顶延迟
1.
The total delay can be calculated from the zenith delay.
为了对大气传播延迟误差进行修正,达到精确测量的目的,推导了天顶延迟的理论计算公式;在大仰角情况下提出了一种简化的映射函数,并把它与连分式映射函数进行了比较。

After some major zenith delay corrective models are analyzed and several mapping function models in continued fraction are discussed and induced,it is concluded that the former corrective models are only based on the atmospheric models of spherical symmetric distribution and adopted almost same isotropic corrective models.
在分析了一些主要的天顶延迟改正模型,并对几种连分式形式的映射函数模型作了归纳后,认为:前者只能都基于大气球对称分布模型,采用差不多相同的各向同性的改正模型,各种映射函数模型的连分式之间,差别仅是形式上的,没有实质性差异。
5) troposphere zenith delay
对流层天顶延迟(ZTD)
6) zenith tropospbric delay
对流层天顶延迟量
补充资料：中性层
指自地面至约60千米高度的大气层。主要由中性气体组成。层内的大气有时可能在局部有较多的带电粒子(如雷暴时)，但一般情况下带电粒子少。
