Abstract: The present disclosure provides an adaptive atmospheric correction method of hyperspectral satellite based on prior ground object spectral matching. The method includes: establishing an adaptive atmospheric parameter retrieval algorithm of hyperspectral satellite data; based on the estimation algorithm of the integrated atmospheric column water vapor content, using a function between a linear regression band ratio and a water vapor content for estimation; in the aerosol optical depth estimation method of the hyperspectral data, using the rich spectral information of the hyperspectral data to perform AOD iterative estimation with the ground object spectral library as prior knowledge in combination with spectral matching, and establishing an atmospheric correction algorithm combining with an MODTRAN radiative transfer model.

Abstract: An artificial respiration apparatus for first aid is provided, and relates to the field of medical first-aid supplies. The artificial respiration apparatus comprises an adhesive film, wherein a fixing block is provided on an upper end of the adhesive film; a first adhesive strip is provided on a lower end of the adhesive film; a second adhesive strip is also provided on the lower end of the adhesive film; and a blowing device is inserted in the fixing block. An intraoral ventilation pipe is inserted into the mouth of a person to be rescued, then the adhesive film is applied to the mouth and nose of the person to be rescued, and finally air is blown into a blowing port such that the blown air enters the body of the person to be rescued through a ventilation pipe, and the intraoral ventilation pipe.
