Abstract: The present invention relates to the technical field of chemical industry, and in particular to a method for purifying ethylene carbonate through dynamic crystallization, which includes the following steps: adding an ethylene carbonate-containing raw material into a cavity of a crystallization device under a condition of stirring for dynamic crystallization, wherein the crystallization device further includes a jacket attached and circumferentially disposed along the outer wall of the cavity, the jacket is provided with cooling water therein, a temperature of the cooling water is 1-2.5° C. lower than the temperature in the cavity until a granular ethylene carbonate crystal is generated. The present invention using a rake dryer as the crystallization device to realize dynamic crystallization at a certain rotating speed. The technical solution is simple to operate and short in processing cycle, which facilitates improvement in production efficiency and product quality and is suitable for industrial application.

Abstract: A method for expanding functions of an ultrasonic imaging device, comprising: identifying and comparing functions of an integrated imaging device and a to-be-expanded ultrasonic imaging device; on the basis of a comparison result, configuring operating parameters and modes of the integrated imaging device and the to-be-expanded ultrasonic imaging device which serves as a host machine; enabling the integrated imaging device to be in communication with the host machine; and operating the integrated imaging device and displaying ultrasound data by means of a user terminal of the host machine. There is no need to make any changes to the hardware of the existing host machine, and new functions can be integrated into the existing device only by upgrading or making minor modifications to the software, such that a new application is derived from a traditional ultrasonic imaging device.

Abstract: A muscle training method and system for providing visual feedback by using ultrasonic imaging.

Abstract: A box for drug management and recycle is provided, which includes a drug box body, a camera device, a card-swiping device, a display device, a processor, and a power supply. A RFID detection device and electronic locks are arranged in the recycle box. A wireless communication module, an early warning module and a processing module are arranged in the processor, and the processor is wirelessly connected to a server terminal. The acquisition and return of the drugs can be jointly completed through face recognition and card-swiping recognition, and can be specified to an individual according to the obtained employee number and other information, thus facilitating the strict management of drug and achieving the recycle of unwanted drug. Therefore, the recycle box has a broad clinical prospect.

Abstract: A biological tissue elasticity dimensional detection method and detection system, and a storage medium. The detection method comprises: using an ultrasonic transducer array to acquiring an ultrasonic image of a target object, establishing a coordinate system of a sampling region of interest, and determining the number of sampling points and coordinate distribution positions thereof; in response to an external vibration excitation, collecting multiple elastic feature parameters at a designated coordinate position, and reconstructing a parameter value that contains spatial position information and a corresponding ultrasonic image, and comprising the synthesis, superimposition and fusion of maps, and simultaneously displaying. Multiple elastic feature parameters within a certain range can be measured by means of a single detection point, not only improving detection efficiency, but also minimizing sampling errors.

Abstract: Disclosed is an optimized energy interconnection system for an urban railway train in the technical field of urban railway transportation power supply, for addressing the technical problem that distribution of regenerative braking energy flows cannot be accurately determined. The system includes a DC intermediate bus and a multi-port flow controllable energy router. The multi-port flow controllable energy router can comprehensively control a source and a load connected in parallel on the DC intermediate bus and thus can accurately determine the distribution of regenerative braking energy flows, thereby forming a well-developed system for evaluating usage of the braking energy.
