| Firstly, the problems in the finery sliding guide are summarized and a new project for sliding guide is come forth. Design is discussed on sliding guide on sliding guide through the solution of Lagrange extremum in math in detail. The best optimum mathematical model is constituted. Scalar factor of structural parameter on loop rectangular Negative Pressure and Adsorption slide is calculated. Structural parameter, air gas source pressure carrying capacity and thickness of air cell are made sure by hydrodynamics and the theory of gas lubrication. The paper describes the mechanism of friction self-oscillation on sliding guide which produced in the motion how speed, deduces the relation of critical is velocity which doesn't produce friction self-oscillation and coarse of sliding guide. It provides reliability for reasonably selecting sliding guide' structure and technical parameter. Then it can provide reliable relation among structural parameter design, parametric adjustment for improving precision in structure. It is very important of parametric confirm during precision detecting and mechanical motion especially. The application for the new negative pressure and adsorption slide in real project is given. The rationality of sliding guide design is validated. Some problems, which will be solved, are advanced.
