The hanger comprises a base, wherein the upper surface of the base is fixedly connected with a first supporting column arranged vertically, the first supporting column is a hollow structure, a second supporting column is inserted in the first supporting column, the second supporting column penetrates through the upper end sidewall of the first supporting column, the inner walls of both sides of the first supporting column are both provided with sliding grooves, the second supporting column is slidably connected with the sliding grooves through sliding blocks, one end, away from the first supporting column, of the second supporting column is transversely fixedly connected with a bracket,the side wall of the lower side of the bracket is fixedly connected with two hanger bodies, the two hanger bodies are respectively located at two sides of the second supporting column, the inner wallof one side of the first supporting column is rotationally connected with a worm arranged transversely through a first rotating part, and one end, away from the first rotating part, of the worm penetrates through the side wall of the first supporting column. The children's clothing hanger capable of being adjusted by lifting conveniently has the advantages that the hanger bodies can be lifted, notonly can a worker take off clothes conveniently, but also the hanger can hang children's clothes with different sizes.

The invention relates to a container universal ventilator containing electric label and the container using the ventilator. The container has through hole on the case, and the ventilator is installed onto the through hole from external. The hollow cavity of the ventilator has electric label. The relative information of the container is recorded in the electric label that could be read by reader in wireless mode. The invention would not influence to the current container, and would be convenient to acquire the information of contains. It is benefit for standardization producing and saves industry cost of using electric label in container industry.

The invention discloses a femoral neck fracture fixing device. The femoral neck fracture fixing device comprises side steel plates, three sleeves, three head nails matched with the sleeves and at least one cortical bone locking screw. The inner surfaces of the side steel plates are matched with the anatomic form of the near-end outer side wall of the thigh bone. The head side of each side steel plate is provided with three conical threaded locking holes, and the tail side of locking the steel plates is provided with at least one cortical bone locking screw. The sleeves of hollow structures. The tail portions of the sleeves are matched with the conical threaded locking holes. The cortical bone locking screws are matched with cortical bone locking screw locking holes. The femoral neck fracture fixing device produces small wounds and is good in fixing effect, simple in operation and accurate in positioning.

The present invention provides a method for optimizing the position of MIMO‑SAR area array antenna elements based on genetic algorithm, which establishes an optimization model of array pattern based on the antenna phase center approximation principle, and uses the minimum peak side lobe ratio and minimum main The lobe width is the optimization target. During the coding process of the genetic algorithm, the position of the array element is selected on the grid point; and two transmitting array elements and two receiving array elements are arranged at the four ends of the array area to ensure that the array The maximum length of the array element; the prematurity of the genetic algorithm is suppressed, and the optimal array element position is obtained; the planar array form with the minimum spacing constraint of the array elements is adopted, and the number of array elements required is greatly reduced, thereby effectively reducing the cost and cost of the antenna system. The amount of calculation is more suitable for the needs of engineering design, and it provides convenience for MIMO-SAR 3D imaging and target detection and recognition.

The invention provides a fabrication template system for custom individual artificial total hip replacement operation acetabulum. The system comprises an acetabulum positioning guide plate, a depth control drill and a colored depth indication rod. The acetabulum positioning guide plate comprises a fossa ovalis positioning plate, an acetabulum bottom positioning plate and a depth guide cylinder. The fossa ovalis positioning plate is attached to the fossa ovalis according to the fossa ovalis dissection shape. The acetabulum bottom positioning plate is arranged at the outer edge of the fossa ovalis positioning plate and is attached to the acetabulum cartilage face according to the acetabulum dissection shape. The depth guide cylinder is arranged on the acetabulum bottom positioning plate and performs guide and depth limitation on the depth control drill. The depth control drill performs drill on the acetabulum through the depth guide cylinder, a depth limit ring protruding from the drill is arranged on the body portion of the depth control drill, and the depth limit ring is limited at the end of the depth guide cylinder through the depth guide cylinder. The length of the colored depth indication rod is identical to the drill hole depth, and the colored depth indication rod is inserted into the hole to indicate the depth and direction. By means of the template system, the ideal acetabulum prosthesis arranging position can be obtained, and accordingly, the acetabulum prosthesis can be arranged accurately, and the operation effect is improved.
