摘要： A method and a device are provided for inspection of liquid articles to determine the presence of drugs concealed in the liquid articles without opening the outer packages. The method includes emitting radiation beams having a single energy to transmit through the liquid article; receiving the radiation beams transmitted through the liquid article to get multi-angle projection data; inversely operating the multi-angle projection data based on the uniformity of the liquid article to obtain an attribute value of the inspected liquid article; retrieving a reference attribute value in a pre-created database by using the identification information of the liquid article as an index, and calculating a difference between the calculated attribute value and the reference attribute value; and determining whether the difference is larger than a predefined threshold value. When the predefined threshold value is exceeded by the difference, it is concluded that there are drugs concealed in the liquid article and this result is output to a user for appropriate action.
