Abstract: Embodiments of the disclosure disclose a display substrate, a manufacturing method thereof and a display apparatus. The display substrate includes: a base, having a wire routing region; a first wire routing layer, located on the base, where the first wire routing layer in the wire routing region includes a plurality of first routing wires arranged at intervals, and a space between adjacent first routing wires is smaller than 2 um; an insulation layer, located on a side of the first wire routing layer facing away from the base and having a plurality of first via holes corresponding to the first routing wires; a first flat layer, located on a side of the insulation layer facing away from the base and having second via holes corresponding to the first via holes, where the second via holes at least partially overlap with the first via holes.

Abstract: A battery slurry, an electrode plate and a lithium battery are provided. The battery slurry includes an aqueous binder and an organic additive. The organic additive includes at least one of —NHR and —SH, where R is alkyl.

Abstract: The present invention discloses a swab sample nucleic acid releaser and use thereof. The sample releaser includes 1-20 mol/L of a metal ion chelating agent, 5-80 mmol/L of a buffer at pH 6-9, 5%-40% (v/v) of a polar organic solvent, 0.2%-10% (v/v) of a surfactant, and 0.1-1 mol/L of a nuclease inhibitor. The sample releaser can integrate three steps of sampling and preservation, inactivation, and nucleic acid extraction into one step, and after sampling, the sample can be directly put into a sampling tube equipped with the sample releaser for storage and transportation; and when in use, the sampling tube is turned upside down and mixed well, and after the sample and the sample releaser are fully mixed, it is let stand for a few minutes at room temperature to release the nucleic acid of the sample.

Abstract: A system for integratedly testing damping performance of a hydro-pneumatic suspension vehicle, including a testing platform and a testing device. The testing device includes a sensor module, a data acquiring and processing module and a testing software. A method for integratedly testing damping performance of a hydro-pneumatic suspension vehicle is also provided. A calculation is performed by a testing software to optimize a sensor configuration. A signal is acquired and transmitted by the sensor module. The signal is acquired and processed by a data acquiring and processing module, and displayed and analyzed by the testing software.
