    摘要： Method and system for liquid detection are disclosed. The method for liquid detection includes: implementing CT imaging and XRD imaging on one or more liquid planes of liquid contained in a container at once by rotating the container so that X-rays from a same radiation source scan a whole area of each of the one or more liquid planes; and generating a substance identification result for the liquid contained in the container based on a CT image and a XRD image, wherein the CT imaging and the XRD imaging are implemented on a same liquid plane or different liquid planes. The invention may identify substances contained in the liquid more quickly and accurately. (Fig. 1)
