The first procedure uses the GAMIT software to estimate parameters such as station position and orbital trajectory on a daily basis for a given 24-hour interval from the union of three data sets:(1) the campaign stations,(2) the continuously operating GPS stations in Antarctica,(3) long-running continuous GPS stations around Antarctica. In the second procedure, we combine the daily solutions with global GPS sub-networks (IGS1, IGS2, IGS3), which is provided by Scripps Institution of Oceanography, using the GLOBK software in a "regional stabilization" approach in order to estimate the positions and velocities.

数据处理分为两步，第一步：运用GAMIT软件进行单天解算，估计站位置、轨道等参数，其数据源主要有以下三类：(1) SCAR GPS观测站；（2）南极的连续跟踪站；（3）南极及其周边的部分IGS站；第二步：运用GLOBK软件加入SOPAC（Scripps Orbit and Permanent Array Center）的全球GPS子网（IGS1、IGS2、IGS3）进行全球网平差解算测站位置和速度。

在苏富比香港春季拍卖会重点推介的拍品中，有一枚乾隆年间的白玉印章，它卖出了9，586万港元，比拍卖前的估价高出了约一倍，一串18世纪的皇家御用项链卖出了6，786万港元，约为拍卖前估价的八倍。

CT findings of GP included gas accumulation under the recess of xiphoid,gas accumulation in the area of lesser omentum,gas accumulation under the recess of peritoneal cavity,and seroperitoneum. Conclusion As a non-invasive examination means for abdomen,CT examination can discover whether there is dissociative gas or not and estimate the amount of gas in abdomen more rapidly and exactly.CT can also estimate the position of perforation elementarily.The recess under xiphoid is the first place where the dissociative gas assembles after gastrointestinal perforation.

Secondly, 4 methods of azimuth estimation based on vector hydrophone according to forms of nosie and signal are brought forward. The principles of these 4methods are set forth, simulating them by computer. Acoustic intensity averager can effectively suppress isotropic non-coherent interference; DOA based on line-spectra can effectively detect the target radiating line-spectra and estimate its azimuth angle; Bar graph approach can suppress line-spectra coherent interference and distinguish different targets radiating line-spectrum. Weighted bargraph approach can detect target in broadband coherent interference and estimate its azimuth angle.
