Abstract: Disclosed in the present invention are a method and apparatus for the identification of fetal cross-sections based on ultrasound dynamic images; the method includes: inputting sequentially each frame of fetal ultrasound images from acquired multiple consecutive frames of fetal ultrasound images into a predetermined feature-detecting model for analysis; acquiring a sequentially exported analysis from the feature-detecting model as feature information for each frame of fetal ultrasound images; corresponding to each frame of fetal ultrasound images, identifying a cross-section by the categories of the part and the structural feature.

Abstract: Disclosed is a pair of specific primers for identifying Asian gypsy moth and a method of detection thereby. In the present disclosure, based on the SS-COI technology, primers for distinguishing other species of Lymantria are designed according to the specific region of the mitochondrial COI gene of Asian gypsy moth. The pair of primers has accurate identification effects on different geographical populations, different insect states and different instars of Asian gypsy moth; in addition, the whole detection process only takes 2-3 hours, which has the advantages of rapidity and accuracy.

Abstract: Provided is a sewage treatment device and method for synchronously recovering water and electric energy, belonging to the field of sewage treatment.
