摘要： A non-destructive testing system for photovoltaic cells includes a non-contact electromagnetic induction device, a short-wave infrared (SWIR) camera or/and a visible-light camera, a thermal imaging device, and an image processing device. The non-contact electromagnetic induction device is configured for generating an external electric field acting on the photovoltaic cell without being in contact with the photovoltaic cell. A direction of the external electric field is parallel to that of an internal electric field of the photovoltaic cell. The SWIR camera or/and the visible-light camera is/are configured for obtaining an optical radiation distribution map within the photovoltaic cell. The thermal imaging device is configured for obtaining a thermal radiation distribution map in the photovoltaic cell. The image processing device is configured for storing and processing the optical and thermal radiation distribution maps. Non-destructive testing equipment including the above system is further provided.

摘要： The present disclosure provides a quantitative accuracy evaluation method and system for a result of remote sensing inversion. The method includes the following steps: acquiring measured data of a target element content in a preset zone; acquiring, based on acquired remote sensing image reflectivity of the preset zone, predicted data of the target element content in the preset zone by a remote sensing inversion model; and conducting comprehensive index evaluation of abnormal feature similarity between the measured data and the predicted data. The technical solution adopted in the present disclosure can solve the problem with quantitative accuracy evaluation of remote sensing inversion that inverted object content and measured object content are distributed inconsistently in space.

摘要： The disclosure relates to a fault-tolerant method and apparatus for a network device system, a computer device, and a storage medium. The method includes: when the link state changes, the source switch acquires and transmits link state change information to the master controller, randomly selects a switch from the first switch unit or the second switch unit, and transmits a copy of the link state change information to the selected switch; such that the master controller forwards the link state change information to the second switch unit, the auxiliary controller receives the copy of the link state change information transmitted by the switch selected by the source switch and transmits it to the second switch unit; after the second switch unit updates the local routing table according to the acquired information, the master controller transmits confirmation information to the source switch.

摘要： Provided is a noise reduction method by cutting a corner of a tooth shoulder of a stator of an AC traction motor based on an inscribed arc. Taking a vertex of a corner of the tooth shoulder of the stator as an end point, two points are selected along two sides of the corner of the tooth shoulder of the stator to allow distances from the two points to the end point to be equal. The two points are determined as tangent points D1 and D2 of the inscribed arc. The tangent points D1 and D2 define the inscribed arc along which the corner of the tooth shoulder is cut off.
