The present disclosure belongs to the technical field of battery materials, and discloses a silicon/carbon composite anode material, and a preparation method and use thereof. The preparation method includes the following steps: S1. dissolving a graphite anode powder in an acid solution, and conducting solid-liquid separation (SLS) to obtain a precipitate; and washing and drying the precipitate, adding a reducing agent, and subjecting a resulting mixture to heat treatment to obtain a purified graphite material; and S2. mixing a modified silicon powder with the graphite material, adding a resulting mixture to a polyimide (PI)-containing N,N-dimethylformamide (DMF) solution, and stirring; and subjecting a resulting mixture to distillation and then to carbonization to obtain the silicon/carbon composite anode material.

Disclosed are a self-adaptive adjustment method and device of a projector, and a computer storage medium. The method includes: acquiring a luminance average value of a current picture, and calculating an absolute value of a difference between the luminance average value and a preset normal luminance average value; simultaneously adjusting the projection luminance and the image luminance if the absolute value is greater than or equal to a first preset threshold value; only continuously adjusting the projection luminance if the absolute value is greater than or equal to a second preset threshold value and less than the first preset threshold value; only adjusting the image luminance if the absolute value is greater than or equal to a third preset threshold value and less than the second preset threshold value; forbidding the luminance adjustment if the absolute value is less than the third preset threshold value.
