摘　　要：空气静压导轨是空气静压止推轴承的一种,在直线气浮导轨中被广泛采用。本文利用线性气源假设,将气膜中气体的二维流动化为一维流动,使雷诺方程得到简单的解析解,推导出空气静压导轨的解析计算公式,并利用该计算公式分析导轨参数对其静态性能的影响,从而为空气静压导轨找到了一种快捷方便的设计方法。The aerostatic guide way is a sort of thrust bearing, and i s applied to linear air guide way widely. This paper assumes that air flow is line ar, that is, assumes that two dimension flows is one dimension flows between gui des, so that the Renault equation has simple analytic solution. Thus, a more pra ctical analytic method of calculation of aerostatic guide way is described in th is paper, and the effect of guide way's parameter on the performance is analyzed .
