Abstract: Disclosed in the present disclosure are an ultra-high modulus and high-transmittance polyimide thin film, and a preparation method and application therefor. The ultra-high modulus and high-transmittance polyimide thin film is prepared by means of mixing and dissolving polydiamine and polydianhydride in a solvent, adding an end-capping reagent, and performing polymerization reaction and imidization. The ultra-high modulus and high-transmittance polyimide thin film has an ultra-high modulus and high transmittance, and is applicable to fields such as flexible photoelectricity and aerospace, especially to a structural member, a reinforcement layer or a substrate of flexible display and transparent display.

Abstract: An assembly includes a seat. The assembly includes a bin adjacent the seat and defining a chamber having an open top. The assembly includes an uninflatable member having a front and a rear and above the open top, the uninflatable member movable to an elevated position with the front and the rear spaced from the bin.

Abstract: An ultra-short-term forecasting method including real-time monitoring of the effect of upper and lower courses, comprising: obtaining ultra-short-term model forecast results through the model lattices based on the T639 global spectral model course library data source, the CALMET wind field diagnostic model and static data; establishing statistical equations on the effect of upper and lower courses between the corresponding reference index station and each target wind tower for obtaining the effect of upper and lower courses of the target wind towers based on the wind tower database of the target wind power base and combined with the wind direction and speed real-time monitoring data of the reference index stations in the upper and lower courses, forecasting the ultra-short-term wind speed changes of each target wind tower and correct combined with the ultra-short-term model forecast results to form forecasting of the ultra-short-term wind speed changes of the wind towers in the target wind power base; after r
