An experimental apparatus for rock-breaking through vibration impact, including a confining pressure loading assembly, a drill bit, a drill rod, a drilling fluid circulation assembly, a rotary impact assembly and an axial impact assembly. The confining pressure loading assembly is configured to apply pressures to a core sample located in a core cavity in three directions perpendicular to each other. The drill bit is capable of inserting into the core cavity to drill the core sample. The drilling fluid circulation assembly includes a drilling fluid inlet, a drilling fluid outlet and a mud pump connected therebetween. The rotary impact assembly includes a hydraulic rotary motor and a hydraulic swing motor connected to the drill rod, respectively. The axial impact assembly includes a first hydraulic cylinder, and a servo linear actuator connected to the first hydraulic cylinder and the drill rod.

A shutter-type adaptive three-dimensional (3D) display system based on medical microscopic imaging is provided. In the system, a binocular camera is connected to an operating microscope optical system through a beam splitter, and is configured to acquire binocular image data. A control module is configured to input control instructions, where the control instructions include a first type of control instructions and a second type of control instructions. An image processing module calculates image parallaxes based on the binocular image data under the first type of control instructions, and transmits the image parallaxes to the binocular camera to adjust offsets. A display module is configured to generate display data based on the binocular image data and display the display data through a display device for viewing with 3D glasses. The operating microscope optical system is configured to perform an adjustment based on the control instructions.
