Abstract: A display substrate, a method for manufacturing the same, and a display device are provided.

Abstract: A device and a method for nondestructively detecting a transient characteristic of a conductive screw of a turbo-generator rotor are provided. The device includes a personal computer (PC), an extremely-steep pulse generator, an ultra-high-frequency double-isolation transformer, and a pulse emitting and coupling module, which are connected in sequence. The pulse emitting and coupling module is connected to a load. A synchronous pulse receiving non-inductive divider circuit synchronously receives a characteristic waveform from the load, and the synchronous pulse receiving non-inductive divider circuit is connected to an ultra-high-speed analog/digital (A/D) module through a nonlinear saturation amplifying circuit that amplifies a signal. The PC receives a signal from the ultra-high-speed A/D module. The load includes a positive or negative excitation lead loop that is in a 180° symmetrical and instantaneous short-circuit state and a rotor shaft.

Abstract: A display panel includes a plurality of sub-pixels and a plurality of gate lines. The plurality of sub-pixels are arranged in an array in a row direction and a column direction, and each row of sub-pixels includes sub-pixels of a first color, sub-pixels of a second color and sub-pixels of a third color. The plurality of gate lines includes first gate lines and second gate lines alternately arranged in the column direction, a first gate line and a second gate line adjacent to each other form a gate line pair, and two gate lines in the gate line pair are coupled to a same row of sub-pixels. In the same row of sub-pixels, sub-pixels of the first color are coupled to the first gate line.

Abstract: The present disclosure provides a grouting and water-plugging device for a fractured rock in a mine coupling state and a test method, and relates to the technical field of rock mechanics testing. The device includes a pressurizer, a reservoir, a test box, and a grouting pump. The reservoir includes a temperature sensor and a pressing-water plate. The pressing-water plate is connected to the pressurizer through a pressurizing rod. A pressure measuring pipe and a drainage pipe are installed on an outer side of the reservoir. The reservoir is connected to a water pump through a water injection pipe. The test box includes a rock, a transverse force exerting plate, a longitudinal force exerting plate, a stress sensor and the temperature sensor. The longitudinal force exerting plate is provided with multiple water through holes. A sliding box door is hinged to a front wall of the test box. The pressure measuring pipe and the drainage pipe are installed on a rear wall of the test box.

Abstract: A hairpiece accessory with a light, thin and soft net bottom includes a net bottom and hair wefts fixed onto the net bottom, where the hair wefts are arranged in rows, and each row of the hair wefts includes a plurality of short hair wefts, the short hair wefts are spaced evenly, and short hair wefts in every two adjacent rows are staggered. In the hairpiece accessory, the staggered hair wefts cover the entire net bottom, which ensures the appearance quality, and avoids the problem of large thickness and hardness of the net bottom, thereby making the hairpiece accessory soft and improving the wearing comfort.

Abstract: A plant-microorganism combined method for phhytoremediation of organic contaminated soil; i.e., an ornamental plant (Impatiens balsamina L.)—microorganisms (petroleum hydrocarbon degrading mixed microbes) combined method for enhanced phytoremediation of petroleum contaminated soil is disclosed. The inoculated petroleum degrading mixed microbes can not only degrade contaminants in soil directly but also secretes chemical substances which are helpful to relieve the toxic effects on the Impatiens balsamina L. In return, the Impatiens balsamina L. releases photosynthesis products into the soil, so as to enhance microbial activity and quantity, and assist the microorganisms in degrading target contaminates more effectively and efficiently. Repeating the processes mentioned above is able to continuously reduce petroleum hydrocarbon contaminants in the soil until the residual content of contaminants meets the environmental safety standard.

Abstract: A method for remediating soil which is contaminated by an individual or a mixture of Cd and Pb with a hyperaccumulator Emilia sonchifolia L. includes steps of: planting seeds or seedlings of Emilia sonchifolia L. in soil which is contaminated by an individual or a mixture of Cd and Pb; watering regularly to maintain the soil moist; after Emilia sonchifolia L. flowers or completely matures, removing all of or an aboveground part of the plant from a contaminated spot of the soil and disposing the removed plant properly; repeating the above steps until a Cd and Pb content of the soil fall within an environmental security standard. Besides being adaptable and widely available, the Emilia sonchifolia L. is both a Cd hyperaccumulator and a Pb hyperaccumulator by respectively satisfying four indexes of the Cd hyperaccumulator and the Pb hyperaccumulator.
