In order to improve the monitoring precision and resolution of tropospheric zenith delay, the hybrid approach, using a batch least squares estimator but parameterizing the zenith delay by a linear spline with knots at 30-minute intervals and treating the knots as a Gauss-Markov process, is employed to deal with the tropospheric zenith delay.
为了提高对流层天顶延迟的监测精度和分辨率，我们采用了分段的参数估计和随机过程相结合的估算方法来处理对流层延迟，由此获得了分辨率分别为2 h和30 min，精度好于1 cm的天顶延迟量。

Based on the ISC earthquake catalogue data, according to the orbit equations of two-body-problem and the perturbation theory of celestial mechanics, we could determine the projection pole of the sun, and thus calculate the zenith distance from the sun to the epicenter. After calculating all the earthquakes on their zenith distances, we could get the distribution of the solar zenith distance versus the occurring probability of earthquakes.
基于ISC地震记录，利用天体动力学中二体问题的轨道方程和摄动理论，确定发震时刻太阳在地面的投影点位置，并进一步计算出太阳相对震中的地心天顶距，将地震按天顶距的大小进行统计，得到地震的太阳天顶距地震频度分布。
