Abstract: A field condition-based experimental apparatus for an ecological indicator of vegetation includes a plurality of isolation units arranged at intervals and an auxiliary mechanism detachably connected to the isolation unit. The isolation units include a plurality of isolation boxes arranged at intervals and respectively having a hollow structure, and a support frame respectively disposed at four corners of the isolation box. The auxiliary mechanism is detachably connected to the support frame. A soil layer is disposed in the isolation box. The experimental apparatus has a reliable structure and is easy to use. An appropriate number of isolation units are buried under field conditions based on experimental needs. Auxiliary mechanisms of different structures are mounted based on experimental conditions. This implements reliable detection of an ecological indicator of vegetation under the field conditions and effectively improves authenticity and reliability of detection results.

Abstract: The field of new compounds and synthesis methods thereof are related, and particularly to a structure of a steric hindrance adjustable weak base light stabilizer and a preparation method and application thereof. According to the innovative light stabilizer, a steric hindrance thereof is adjusted by establishing substituent generating the steric hindrance around nitrogen atoms; moreover, an electronegativity of the nitrogen atom can be influenced by adjusting a distance of a polar group, so that an alkalinity or a nucleophilicity of the nitrogen atom is adjusted. A desired effect is obtained by adjusting a steric hindrance and a nucleophilic property or an alkalinity where the nitrogen atom is located, so that an application range of the innovative light stabilizer is widened, and the innovative light stabilizer is suitable for PC, polyester, PVC and other slightly acidic or certain electrophilic polymer materials to serve as a light stability protecting aid.

Abstract: A method for driving a display panel is disclosed. The display panel includes a plurality of sub-pixels arranged in an array, a plurality of data input ports, a plurality of groups of data lines, and a plurality of groups of selection switches, wherein each group of data lines includes a plurality of data lines coupled to the same data input port through a plurality of selection switches in a corresponding group of selection switches. The method includes: sequentially turning on a plurality of selection switches according to a first sequence when an Mth row of sub-pixels of the display panel is scanned; and sequentially turning on the plurality of selection switches according to a second sequence when an (M+1)th row of sub-pixels of the display panel is scanned, wherein M is a positive integer greater than or equal to 1, and the first sequence is different from the second sequence.

Abstract: An array substrate, a display panel and a driving method thereof, and a display device are provided. The array substrate includes a plurality of pixel units arranged in an array, each of the plurality of pixel units includes at least four sub-pixel units corresponding to different colors. When the array substrate displays a frame of image, in each row of pixel units, polarities of pixel voltages received by two sub-pixel units corresponding to the same color in adjacent two pixel units are different; a polarity of each pixel voltage represents the magnitude of each pixel voltage relative to a common voltage.
