Claim Text:
1. A method for inspecting liquid, comprising steps of: determining whether the package of liquid is transparent, semi-transparent, or opaque; if the package of the liquid is transparent or semi-transparent, pointing a transparent or semi-transparent package portion of the inspected liquid to a laser output end of a Raman spectrum module and controlling the module to output a laser beam to implement Raman spectrum analysis on the inspected liquid, comparing the Raman spectrum of the inspected liquid with standard Raman spectrum of the liquid in a database to obtain an analysis result of the inspected liquid, and judging whether the inspected liquid is dangerous or is suspected; and if the package of the inspected liquid is opaque, inspecting the inspected liquid using an X-ray dual-energy scanning technology to obtain physical properties of the inspected liquid, comparing the obtained physical properties with standard predetermined information of the liquid in the database to obtain an analysis result of the inspected liquid, and judging whether the inspected liquid is dangerous or is suspected.
