The fixed plate is further provided with a flipped cylinder. The cylinder barrel of the flipped cylinder is hinged on the fixed plate, and the piston part of the flipped cylinder is connected to the lower part of the operation platform.

Abstract: Provided are a silicene quantum dots-containing siloxene thin film and a preparation method therefor, which belong to the field of fluorescent functional nanomaterials. A siloxene thin film embedded with silicene quantum dots is prepared by uniformly mixing CaSi2 with a decalcification organic solvent and a transition metal chloride catalyst in a proportion, performing acid washing, and then performing ultrasonic dispersion. The thickness of such siloxene thin film is less than 1 to 2.5 nm, the size of the silicene quantum dots is 2 to 5 nm. In addition, the siloxene thin film has strong fluorescence emission performance in a blue light region, has a pseudodirect band gap, and shows a good application prospect in the fields of photoelectricity and the like.

Abstract: Provided are a method and an apparatus for displaying content on a same screen and a terminal device. The method includes: displaying an application interface of an application on a display apparatus, and displaying a floating region on the same screen as the application interface; setting a content loader corresponding to the floating region; determining display content of the floating region; and invoking the content loader to load the determined display content to the floating region for display.

Abstract: A microangiography method and system based on full-space modulation spectrum splitting and angle compounding is disclosed. Label-free three-dimensional optical coherence tomography angiography is realized by combining the three-dimensional space resolution capability of an optical coherence tomography and the motion recognition capability of a dynamic scattering technology. Probe light of different incident angles is encoded with a transverse scanning modulation spectrum in a spatial frequency domain, incident angle-resolved sub-angiograms which are independent of one another are obtained by splitting the modulation spectrum, and an angiogram with multiple space angles compounded is realized. Conjugate mirror images are removed from a depth (z) domain, a complex-valued OCT interference spectra are reconstructed, the full-space modulation spectrum is obtained in the spatial frequency domain, and the overlap of the modulation spectrum conjugate mirror images is avoided.

Abstract: The present application discloses a balloon holder comprising a body and a plurality of fixtures. The body comprises an inner perimeter and an outer perimeter, wherein the inner perimeter defines a void. The plurality of fixtures is coupled to the body, each of the plurality of fixtures comprises a first slot and a second slot connected to one end of the first slot, wherein another end of the first slot is connected to an edge of the fixture. A method for using the aforementioned balloon holder is also disclosed. The method for using a balloon holder comprises inserting a first plurality of balloons into the plurality of fixtures through the first slot and the second slot; inserting a second plurality of balloons into the plurality of fixtures through the first slot and the second slot; and inserting a central balloon into the void.
