With high acceleration and ultra-precision requirements,the design of aerostatic bearings has been gradually focused on their dynamic performances.In this paper,the dynamic stiffness and damping coefficients o aerostatic bearings are investigated.Due to compressibility of the gas,the dynamic characteristics of aerostatic bear ings show nonlinear frequency dependence.Particularly their nonlinear dynamic behaviors are quite remarkable fo ultra-precision aerostatic bearings with small air gap heights and high supply pressure.
With high acceleration and ultra-precision requirements, the design of aerostatic bearings has been focused on their dynamic performance. In this paper, the dynamic stiffness and damping coefficients o aerostatic bearings are investigated. aerostatic bear ings show nonlinear frequency dependence. Partially their nonlinear dynamic behaviors are quite remarkable fo ultra-precision aerostatic bearings with small air gap heights and high supply pressure.

湟水北岸的柳湾村是一个僻静的地方，但并不冷漠。 20世纪70年代以前，这个静谧的小村子，每天早晨，庄户里的人家从梦里醒来了，他们不太注意自己家的院子里正在盛开的白色的苹果花或者粉色的杏花，更不会在意他们身后，被柳树掩映着的土黄色的大山。所以，女人们只是去喂她们的鸡，男人们则背着手轻松地走在田埂上，去查看昨天夜里刚浇过水的麦田。南来北往的司机和乘客看到的也只是满眼的绿色和离脚边不远的漫漫的湟水，谁
