  • Publication number: 20240082166
    Abstract: An oral capsule formulation of a PARP inhibitor and a preparation method. The oral capsule formulation comprises a solid dispersion powder of an active ingredient 5-fluoro-1-(4-fluoro-3-(4-(pyrimidin-2-yl)piperazine-1-carbonyl)benzyl)quinazoline-2,4(1H,3H)-dione, a filler, a disintegrant, a glidant, and a lubricant, wherein less than 10 wt. % of the active ingredient in the solid dispersion powder is in a crystalline form. The defects of the fluidity, hygroscopicity and cohesiveness of the solid dispersion powder which result in the difficulty of production scale up of capsule formulation are addressed, and thus commercial scale production can be achieved, and the prepared capsule exhibits proper dissolution rate, excellent storage stability, meanwhile with a reasonable production cost.

  • Publication number: 20210293625
    Abstract: A multi-spectral temperature measuring device based on adaptive emissivity model and temperature measuring method thereof are provided, which is configured to measure the temperature of the surface of an object under a high temperature background. The present invention relates to the technical field of radiation temperature measurement. The present invention provides a multi-spectral temperature measurement device based on an adaptive emissivity model, includes a pyrometer, a radiation detector, a constant temperature furnace, a cooling cavity, a cold air inlet pipe, a cold air outlet tube, and a thermocouple and thermocouple acquisition card. In order to more accurately measure the surface temperature of the object in a high-temperature environment, a BP network is provided to adaptively find the emissivity model, and through pre-training the network, the network has a high degree of recognition, and then classifies the spectral curve to accurately output the corresponding emissivity model.
