Abstract: For trapping atoms, an x-axis wire carries an x-axis current I0cos ?t, wherein I0 is current amplitude, ? is a trap field frequency, and t is time. A y-axis wire carries a y-axis current I0sin ?t, the y-axis wire intersecting the x-axis wire at a cross center. A ?-field coil generates a transverse magnetic bias field ? rotating about the cross center and perpendicular to a z axis. A ?-field coil generates a longitudinal magnetic bias field ? rotating about the cross center and perpendicular to the z axis. The x-axis wire, the y-axis wire, the transverse magnetic bias field ?, and the longitudinal magnetic bias field ? form a time-averaged trap along the z axis near the cross center.

Abstract: An expression recognition method and apparatus are provided. The method includes: acquiring a to-be-recognized image; obtaining an image feature map of the to-be-recognized image according to the to-be-recognized image; determining global feature information and local feature information according to the image feature map; and determining an expression type of the to-be-recognized image according to the global feature information and the local feature information.
