介绍了快速测定活动断层带CO2 气体的方法、川西地区断层气CO2 观测点的选建以及观测的情况。初步的观测结果显示，在 1999年四川绵竹两次 5 0级地震、 2 0 0 1年四川雅江 5 0级和 6 0级地震和 2 0 0 1年云南永胜 6 0级地震前，部分观测点的断层气CO2 均有很好的短期前兆异常显示。

The junk rating is the percentage of the submitted message that was not useful (i.e., material that was not observational records, observational header or e-mail header). Many messages arrive with junk ratings of more than 50 percent (in some cases, more than 90 percent!). If you get a poor junk rating, you should examine what you are actually sending and try and cut out some of the junk that some PC mailers seem to insert.

用百分比表示，表示你上报的无用信息的多少（比如：非观测记录内容，非报告头或EMAIL文件头等）很多报告包括50%以上的垃圾信息（有些甚至超过90%），如果你发现你的上报有太多的垃圾，请自己检查你的报告，去掉不该添加的内容，有些邮件服务商会自动添加广告内容。
