摘　　要：在文件广播网上传输具有UCL(统一内容定位)标引的网络热点信息,一方面可有效缓解"信息不可控"和"信息垃圾"等问题,另一方面可以使网络上某些特定信息得到更加广泛的共享。在基于UCL的文件广播系统硬件平台和VC软件环境下,结合数据发送卡和接收卡的API函数以及利用ADO操作数据库,完成了信息发送端和接收端软件的研究与设计,并对实验系统进行了测试和分析,实现了具有语义标引网页文件在广播网上的传输。实验结果验证了此系统在带宽和信息可控性方面的优越性。Transmitting the hot web information with UCL indexing in the documents broadcasting system can effectively relieve some problems such as ＂uncontrollable network information＂ and ＂information rubbish＂, and also make some specific information shared more widely. Under the platform of the documents broadcasting system based on UCL, the sending software and the receiving software were researched and designed under the VC platform, and then the whole experimental system was tested and analyzed, which accomplished the transmission of the semantic index files in the broadcasting network. Results of the experiment prove that the files broadcasting system based on UCL is superior in the field of bandwidth and information controllable.
