<正>The cover picture is taken from the article"Design and Testing of a Novel Passive Isolator for a Space Optical Payload"and shows the application of the proposed vibration isolator to attenuate the micro-vibration of the space telescope.For the space telescope with a large aperture and high image resolution,micro-vibration generated by on-board motion equipment in spacecraft can greatly degrade the image quality of the telescope.The general approach is to use the vibration isolator.In
