Abstract: A skin layer of a superconducting tape has a woven mesh structure and is disposed on a surface of a superconducting tape. The skin layer of a superconducting tape solves the problem where a vapor layer generated when a superconductor is in a normal resistive state greatly reduces the efficiency of a heat exchange between the superconductor and liquid nitrogen. Further provided are the superconducting tape and a superconducting coil.

Abstract: An electric quantity indicating method and an electronic device are provided. The method is performed by an electronic device. The electronic device includes a device body and a detachable camera module. The method includes: receiving first information sent by the detachable camera module, where the first information includes electric quantity information of the power supply of the detachable camera module; and according to the first information, displaying a target identifier on the device body; where the target identifier is an electric quantity identifier of the power supply of the detachable camera module in the electronic device.

Abstract: A verification method, includes: in a case that the first operation does not meet a verification condition, adjusting a current value of a first sub-region in the verification region, or increasing an area of the first sub-region in the verification region, or adjusting a current value of a second sub-region in the verification region. The verification region includes the first sub-region and the second sub-region, and after the current value of the first sub-region or the current value of the second sub-region is adjusted, the current value of the first sub-region is greater than the current value of the second sub-region.

Abstract: Thorough optimization and improvement have been made on the basis of original closed-shelf stack room by the unattended full-automatic book management system of the invention. The concept of a book basket is brought in to process an order of each borrower in a batch. The device is simplified and the efficiency of single functional part is enhanced during the period of storing books, taking books, returning books, conveying a book basket and transmission, thereby the functions of the whole system being optimized. The system includes bookracks, a laneway vehicle, a laneway vehicle interface, a transmission device, a book taking window, and a book returning window, and further includes a book basket and a book box independent of the bookracks.
