Abstract: A method and apparatus for controlling the flight of an Unmanned Aerial Vehicle (UAV) are provided. The method includes: determining a starting flight position where a UAV is parked currently and a nose direction of the UAV (101); starting off from the starting flight position, and flying along a straight line in the nose direction (102); and when receiving a route adjustment instruction during the flight of the UAV, adjusting an air route of the UAV according to the route adjustment instruction (103). During the flight, an operator can correct an air route via a remote control apparatus without surveying and mapping when detecting that the UAV is flying off course; and the operator can make the UAV precisely fly along a desired straight line by means of simple operations.

Abstract: Embodiments of the present invention provide a machine learning model training method, including: obtaining target task training data and N categories of support task training data; inputting the target task training data and the N categories of support task training data into a memory model to obtain target task training feature data and N categories of support task training feature data; training the target task model based on the target task training feature data and obtaining a first loss of the target task model, and separately training respectively corresponding support task models based on the N categories of support task training feature data and obtaining respective second losses of the N support task models; and updating the memory model, the target task model, and the N support task models based on the first loss and the respective second losses of the N support task models.

Abstract: A conveying apparatus includes a holding plate having a holding surface destined to face a surface of a wafer to be held; a restriction member on one end side of the holding surface adapted to contact the periphery of the wafer so as to restrict movement of the wafer; and a moving unit adapted to move the holding plate. At the holding surface, a non-contact type suction holding part is adapted to jet a fluid obliquely to the surface of the wafer to be held so as to move the wafer toward the restriction member and generate a negative pressure between the holding surface and the surface to be held, thereby holding the wafer by suction. The fluid is jetted from the suction holding part so as to abut the wafer against the restriction member, thereby positioning the wafer at a predetermined position on the holding plate.

Abstract: A method for conversion treating a surface of a magnesium alloy workpiece includes the following steps: providing a magnesium alloy workpiece, degreasing the magnesium alloy workpiece, acid pickling the magnesium alloy workpiece in a first acid pickling treatment step, surface conditioning the magnesium alloy workpiece in a first surface conditioning treatment step, acid pickling the magnesium alloy workpiece in a second acid pickling treatment step, surface conditioning the magnesium alloy workpiece in a second surface conditioning treatment step, pre-phosphating the magnesium alloy workpiece in a pre-phosphating treatment step, and phosphating the magnesium alloy workpiece in a phosphating treatment step to form a phosphating film on the surface of the magnesium alloy workpiece.

Abstract: A vanadate solution for conversion treating of surface of a magnesium alloy workpiece contains 8.20×104 to 8.20×10?2 mol/liter of metavanadate ion, 1.18×104 to 1.18×10?2 mol/liter of a polyhydroxylated aromatic compound, and balance of water. The pH value of the vanadate solution exceeds 1 and is less than 4. A method for preparing the vanadate solution is also provided.

Abstract: A shoe with changeable upper design includes a shoe body having a sole and an upper connected to the sole. The upper has an outer surface provided with at least one decorative portion which includes an indented surface and a first pattern provided on the indented surface. At least one decorative pad having a front side provided with a second pattern is further provided. The decorative pad is attachable to and removable from the indented surface of the upper so that the first and second patterns can be interchangeably presented on the upper.
