摘　　要：采用分子模拟的方法研究了压力对氩流体在铂狭缝中滑移的影响,获得了压力对流体分布、滑移速度和滑移长度的影响规律。研究结果表明,随着压力增大,会出现密度为零的情况,并且流体的滑移速度和滑移长度逐渐增大。The influence of pressure on the slip of the argon fluid in the platinum slit is studied by molecular simulation.The influence of pressure on the distribution of fluid,the slip velocity and the slip length are obtained.The results show that with the increase of pressure,there will be a density of zero condition.the slip velocity and the slip length increase gradually with the increase of pressure.
