The paper holds the idea that, parallel bus can;t adapt to high-speed transfers due to self-limitations, and high-speed serial point-to-point bus will substitute for traditional parallel bus; data transfer will not be carried out simply by drive circuit and parallel bus, but by special high-speed serial bus; the traditional mode of single bus loading multi-device is disappearing, and a centralized switch module is replacing the bus function in a mode of one switch module connecting all devices via high-speed point to point serial bus.

文章认为并行总线由于自身缺陷，已经不适合进行高速传输，高速串行点对点连接将代替传统的并行接口；数据交换也不再是简单地通过驱动电路和并行数据线进行，而是通过特殊的串行高速总线连接；传统的在一条总线上同时挂载多个设备的模式正逐渐消亡，总线功能已被一个集中式的交换模块取代，而交换模块和各个设备都是通过高速串行点对点的方式进行连接。

They first organize and analyze a set of data with the stem-and-leaf diagram. They point out that the diagram is used for a small number of data and the original data can be retained in the diagram. To compare two different set of data of the same nature, they propose the use of a back to back stem-and-leaf diagram.

The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.
