摘要
报道了美国用原子力显微镜可直接检测超微型设备内发动机转子与外壳表面上凸点之间摩擦力的大小的研究成果 。
The method of detecting the friction force between the motor rotator of ultramicroscopic instruments and the uneven nanometer level surface of shells with atomic force microscope(AFM) is reported. The method of decreasing the friction force of motor is introduced.
