Abstract: The present disclosure relates to a method for analyzing a geological body with the help of physical and chemical properties thereof, and in particular, to a method for identifying an exudative sandstone uranium deposit. With the method for identifying an exudative sandstone uranium deposit according to the embodiments of the present disclosure, an exudative sandstone uranium deposit formed by an exudation metallogenesis may be systematically identified, so as to guide prediction and prospecting evaluation of a uranium deposit in red variegated sandstone formations of a sedimentary basin, avoid ore dislocation and ore leakage, open up new prospecting positions and spaces, and break through new uranium resources.

Abstract: a waterproofing device for electronic equipment is provided, which includes: sensing unit, arranged in a shell of the electronic equipment and configured to output corresponding sensing signal when sensing that water permeates into the electronic equipment; and a powering-off unit, configured to generate a powering-off signal to power off the electronic equipment according to the sensing signal. In the invention, after water is sensed to permeate in the electronic equipment, power of a circuit board of the electronic equipment is immediately and automatically cut off, so that the problem of high short-circuiting rate of the circuit board after water permeates into the electronic equipment is solved, and an effect of avoiding loss is further achieved to a great extent.
