  • Publication number: 20240158737
    Abstract: The invention provides an Escherichia coli for synthesizing L-valine, a construction method and use thereof. The Escherichia coli of the invention is designated as Escherichia coli W3110 and was deposited in China Center for Type Culture Collection (Address: Bayi Road, Wuchang District, Wuhan City, Hubei Province) under the Accession No. CCTCC M 2022293 on Mar. 18, 2022. The recombinant Escherichia coli takes Escherichia coli as a starting strain, and a transcription regulation factor is overexpressed to obtain a recombinant Escherichia coli. The recombinant Escherichia coli for synthesizing L-valine of the invention is fermented in a 5 L fermentor with trace dissolved oxygen to test strains, the yield of L-valine reaches 112 g/L, and the OD of the bacterium is 104.

  • Publication number: 20230383671
    Abstract: Disclosed in the present invention is a safety control method for a generator of a gas turbine power plant. The method includes the following steps: acquiring a safe power-receiving range value of a load, determining an output voltage of the generator, acquiring a ratio of rated power of the generator to a rotational speed of the generator, and acquiring a temperature difference between an internal temperature and an external temperature of the generator. In the present invention, stable voltage output of the generator is ensured by controlling the rotational speed, the number of turns of an output coil winding and a torque output value of the generator, such that stability and safety of operation is improved, an energy utilization rate is improved, and great significance for energy conservation, emission reduction, and energy loss reduction is achieved.

  • Patent number: 10224378
    Abstract: An organic light emitting diode pixel arrangement structure includes multiple first sub-pixels, multiple second sub-pixels, and multiple third sub-pixels. Two adjacent first sub-pixels are arranged in a first sub-pixel group, two adjacent second sub-pixels are arranged in a second sub-pixel group, two adjacent third sub-pixels are arranged in a third sub-pixel group. The multiple sub-pixels form multiple arrays, and each array includes at least one first sub-pixel, at least one second sub-pixel and at least one third sub-pixel, each of the first, second and third sub-pixel groups corresponds to a square opening of a mask plate in an evaporation process, there is an inclination angle between a side of the square opening and an arrangement direction of a linear evaporation source, and the inclination angle is an acute angle or an obtuse angle.
