中文摘要：

针对传统便携式X射线荧光仪的单一功能，无法实现实时联网通讯传送数据的情况，提出了基于DM9000网卡芯片和传统便携式X射线荧光仪相结合的应用。使得便携式X射线荧光仪在不借用个人计算机平台的情形下，通过把DM9000芯片扩展到ARM嵌入式处理器S3C2440所控制的仪器系统中，实现了直接联网传送数据的功能，因此这种应用具有非常重要的现实意义。

英文摘要：

The traditional portable X ray fluorescence analyzer, can not realize real -time network communication data transmission. The author proposes the application of DM9000 card chip combined with the traditional portable X - ray fluorescence analyzer without the use of a personal computer. By including DM9000 chip into ARM embedded processor S3C2440 control, the direct network data transmission function can be realized, so it has great significance for real application.
