Our study has the following findings: most of the network bandwidth is used by P2P software to transfer the files, approximately 34%. Among the P2P software, the largest service item is the eDonkey, approximately 24%. Most of the traffic in each group is used by only a few users. The behaviors of the broadband users are significantly different than the narrowband users. To download the files is the major purpose of the broadband users, but the narrowband users are used to get their Emails. The files with the video files extensions of dat、mpg、avi and with image file extensions of iso、mdf、img are the primary file types transferred by campus users.

本研究发现：占用频宽最大比例者为P2P软体之档案资料传输，约占总频宽34%，其中最大项目为eDonkey，占总频宽使用量约24%；群组的流量，大部分是群组内少数使用者所使用；宽频及窄频使用者行为有显著不同，其中，宽频使用者是以下载档案为主，而窄频使用者是以收信为主；在档案的传输中，以副档名为dat、mpg、avi等影片档及副档名为iso、mdf、img等光碟映射档为主要传输类别。

The algorithms estimate the DOA of the broadband distributed source fron the secondary diagonal elements of the covariance matrices generated from every frequency domain of the received broadband signal s, thus avoiding unwrapping of phases.

该类算法首先将阵列接收的宽带信号变换到频率域，然后对于每个频率形成阵列接收信号协方差阵，最后由该协方差阵的次对角线元素估计宽带分布源的到达角，其主要特点是避免了相位展开。

With this velocity model and broadband records from 5 CDSN stations, we inverted focal mechanisms of Chifeng earthquake on August 16th, 2003 with the "Cut and Paste" method. Then we confirmed focal depth and the source mechanisms by comparing synthetic body waves at teleseismic distance with broadband records of 9 IRIS stations. Our result shows that the best double couple solution of this M w5.2 event is 315°, 64° and 19°for strike, dip and slip angles respectively, the second nodal plane solution is 216°,74°, and 152°. The focal depth is 25±2 km, suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.

我们以此速度结构作为模型，利用中国国家地震台网5个台站的宽频带地震数据，采用CAP方法反演2003年8月16日赤峰地震震源机制解并初步确定震源深度；再利用IRIS 9个台站远震体波数据，通过对比理论计算和观测记录的方法进一步精确确定震源深度并验证反演得到的机制解，得出此次地震矩震级为5.2，震源机制解为：节面I：315°/64°/19°，节面II：216°/74°/152°，震源深度为25±2 km，已深达下地壳。
