The Linux OS is used in various devices, but not in real-time fields mostly. The real-time performance of Linux kernel is analyzed between the 2.6 and 2.4 kernel, using the LmBench tool. A test method is introduced to compare the real-time performance, based on two preemption strategies. It is concluded that the real-time performance of the 2.6 kernel has been greatly improved, which can basically meet the requirements of real-time systems.

The technology of 2D GM-SYS gravity-magnetic inversion improved the reliability of geological sections, but the result of inversion can’t be imported into the GoCAD software to build the 3D geological model directly. A software, named G2G, is developed based on the file formats of GM-SYS and GoCAD, to transfer the GM-SYS inversion sections into GoCAD software format’s files, improving the efficiency of 3D geological modeling.

The data file's format of 3D model generated by GoCAD is researched, and a 3D Visualization System for GoCAD objects is developped based on VTK visualization graphics library and QT platform. It can load the pointset, curve, surface files exported from GoCAD model into true 3D render window, suplies tools for geologists to analise the geological model. It is more convinient to view and analise the geological model in true 3D compared with GoCAD.
