Abstract: Disclosed is a measurement and control method, device, and electronic equipment for motor current and speed. The method comprises: obtaining an input speed and an input current, obtaining a motor measurement and control model, inputting the input speed and the input current into a motor measurement and control model for measurement operation to obtain a current motor speed, obtaining a motor explicit control rate, and conducting a current calculating based on the current motor speed and the input speed under the motor explicit control rate to obtain a reference current; conducting a current calculating based on the reference current and the input current to obtain a current value of the current, and controlling the motor based on the current value of the current. The method measures the motor speed and current through motor measurement and control model, generates more accurate reference currents, and achieves precise control of the motor.

Abstract: Provided are an ovary-targeting polypeptide, a derivative of the polypeptide, and the use of the polypeptide in the preparation of a drug or reagent for treating ovarian related reproductive diseases and preventing and treating the in-vivo or in-vitro aging of oocytes. The diseases comprise menstrual cycle disorder, polycystic ovary syndrome, androgenic phenotype, hair loss, abnormal metabolism, ovarian insufficiency, premature ovarian failure, ovulation failure, abnormal glucose metabolism, and abnormal lipid metabolism, preferably, hyperglycemia and insulin resistance. In addition, the polypeptide is expected to prolong the preservation time and improve the preservation quality of oocytes or fertilized eggs in the field of assisted reproduction.

Abstract: An intelligent assistance system and a method for berthing and unberthing based on multi-tugboat collaboration are provided.

Abstract: Provided is a liquid sample sampling device used in an operation, and belongs to the technical field of sampling devices. The sampling device includes a negative pressure suction head, an auxiliary tube connected with a side wall of the negative pressure suction head, and a sampling bottle connected with the auxiliary tube. A rebound connecting plate is arranged at a position connecting the negative suction head and the auxiliary tube. The side wall of the negative pressure suction head is provided with a push switch. A diameter of the auxiliary tube is larger than a diameter of the negative pressure suction head. The push switch is an elastic membrane switch.

Abstract: A squid-type marine oil containment device includes a track and four oil containment booms. A robotic arm is provided in an elliptic area formed by the track. Sliders are provided on the track. Ends of oil containment booms slide along the track through sliders. Each oil containment boom includes an oil suction pipe, propellers and a plastic separating layer. A middle of the oil suction pipe forms an oil channel. Booster pumps are spacedly provided inside the oil suction pipe and are respectively connected to a hose. Pairs of propellers are spacedly provided at a lower end of the oil suction pipe. Oil suction holes are provided on the oil suction pipe. The plastic separating layer is provided under the oil suction holes. A counterweight is provided at a bottom of the oil containment boom. The invention further provides a method of containing oil using the device.
