Abstract: A display panel includes a substrate, a thin-film transistor layer disposed on the substrate, an auxiliary layer disposed between the substrate and the thin-film transistor layer and including a first auxiliary layer and at least a second auxiliary layer disposed on a side of the first auxiliary layer close to the substrate. A dielectric constant of a constituent material of the first auxiliary layer is less than a dielectric constant of a constituent material of the substrate and is greater than a dielectric constant of a constituent material of the second auxiliary layer. The second auxiliary layer includes a plurality of auxiliary portions arranged at intervals.

Abstract: The present disclosure is directed to a microscope tube including a ocular optical path including a collecting lens, a deflecting optical system, a binocular unit and an eyepiece, wherein light emitted from an objective enters through the collecting lens and is transmitted into the binocular unit via the deflecting optical system to allow a human eye to observe by the eyepiece at a visual angle, wherein the deflecting optical system includes a fixed deflecting optical components group and a rotatable deflecting optical components group located after the fixed deflecting optical components group along a light transmission path, the visual angle being adjustable by the rotatable deflecting optical components group, and light emitted from the objective reaching the binocular unit after an even number of reflections of at least four times by the deflecting optical system.

Abstract: The present invention relates to a method of increasing the foaming properties of detergent compositions comprising at least one surfactant by incorporation of saccharide isomerate.

Abstract: A method and apparatus for mining a tag, a device, and a storage medium are provided. The method may include: determining an existing tag and a category of the existing tag; determining a candidate tag from a target text associated with the category based on the existing tag; and combining the existing tag and the candidate tag, and determining a new tag based on a combining result.

Abstract: The invention is directed to a surgical microscope and a device for switching the same among multiple working modes. The device includes an illumination rotary member and an observation rotary member that are arranged, respectively, in the illumination beam path and the observation beam path of the surgical microscope and are drivable by the same power source to rotate synchronously among multiple rotary positions corresponding to the multiple working modes. In each of the rotary positions, light from a light source of the surgical microscope passes through one or more of multiple light-through-portions of the illumination rotary member along the illumination beam path to illuminate the observed object, and then passes through one or more of multiple light-through-portions of the observation rotary member along the observation beam path to reach the eyepiece and/or an observation instrument of the surgical microscope.
