Abstract: A high-throughput test chip includes: a backplane, a cover plate and a connector. The backplane and the cover plate are aligned to form a plurality of accommodation chambers. Test chip units are disposed on one side of the backplane facing the cover plate, and each of the test chip units is located in the corresponding accommodation chamber. Each of the accommodation chambers is provided with a liquid inlet and a liquid outlet. The connector includes pipelines; each of the pipelines is provided with a valve structure configured to control connection or disconnection of the pipeline. In each pair of a pipeline and an accommodation chamber, an inlet of the pipeline communicates with the liquid outlet of the accommodation chamber; the pipelines form at least one pipeline group, each pipeline group at least includes two pipelines, and the pipelines in each pipeline group share the same sample liquid outlet.

Abstract: The disclosure discloses a battery device, a detection method thereof, a method and device for screening battery cells. The characteristic values are determined according to parameters of two peaks in the frequency-domain impedance diagram. The characteristic values may reflect the magnitude of charge transfer impedance and diffusion impedance in each battery cell, then reflect the characteristics of the interface and characteristics of solid phase particles during charging and discharging, and further reflect the health and performance of battery cells. The battery set screened in this way still have good consistency after storage and shelving, and the consistency between battery cells will not deteriorate after storage for a period of time, so that the battery device may have better performance.

Abstract: The present invention discloses a method for preparing an ibuprofen spherical crystal having high bulk density and a product thereof. The method includes: (1) heating ibuprofen until a molten liquid state is reached; and (2) pressurizing the molten liquid state of ibuprofen, dropping the molten liquid state of ibuprofen into a crystallizer filled with water through a liquid distributor for crystallization under stirring conditions until the molten liquid state of ibuprofen is completely dropped, lowering the rotation speed of stirring to allow crystal growing, and finally, subjecting a resulting crystal slurry to post-treatment to obtain the ibuprofen spherical crystal having high bulk density. The ibuprofen spherical crystal has a bulk density of 0.50-0.70 g/mL, a tap density of 0.63-0.89 g/mL, a median particle size of 300-1,000 ?m and an angle of repose of 22-29°.

Abstract: The present invention discloses an opposite belt-type precise seeding device. The opposite belt-type precise seeding device comprises a seed metering tube consisting of a U-shaped shell and a cover plate, two conveying devices provided inside the seed metering tube in parallel, and a conveying plate provided at the lower end of the seed metering tube. The opposite belt-type precise seeding device belongs to the field of agricultural machinery. In a seeder, a tubular seed conveying tube is usually used for guiding movement of seeds, but the movement of the seeds in the seed conveying tube has certain randomness, so that the seed distance consistency of the seeds in a seed bed is reduced. Through control of the seeds by the conveying devices, the stable movement of the seeds is achieved and the seed distance consistency of the seeds in the seed bed is guaranteed.
