Abstract: The present disclosure provides a curvature determination method, a curved display panel, and a display device. The curvature determination method includes: establishing a first association relationship between deflection and a shear stress of the curved display panel in a first direction, the first direction being a bending direction of the curved display panel; determining a constraint condition for the shear stress in accordance with an influence of the shear stress on a light leakage of the curved display panel; and generating a curvature change relationship of the curved display panel in the first direction in accordance with the first association relationship when the constraint condition has been satisfied.

Abstract: This application discloses a task processing method. The method is applied to a computer system, and the computer system includes a user mode and a kernel mode. The user mode includes a plurality of tasks, and the tasks are threads or processes. The method includes: detecting, in the kernel mode, a type of a first request of entering a kernel entry; when the type of the first request indicates that a first task is suspended in the user mode, switching at least from a user-mode context of the first task to a user-mode context of a second task, recording a suspended state of the first task and a running time from a moment of starting to run the first task to a moment of suspending the first task, and skipping processing other scheduling statuses of the first task; and running the second task in the user mode.

Abstract: This invention provides a fermentation method of producing gellan gum, wherein a certain amount of fermentation broth is retained in the fermentor as a seed for next batch fermentation or transferred to another fermentor as a seed for next batch fermentation in that fermentor. The fermentation method of this invention reduces fermentation cost of gellan gum and lowers contamination risk during seed cultivation.

Abstract: The invention provides a new fermentation process for producing gellan gum, which can control the feeding amount and feeding speed of the nitrogen sources accurately and quantitatively, and control the growth and gum production of the strains, so as to significantly improve the controllability, stability and yield of the fermentation process for producing gellan gum.
