Abstract: Embodiments disclose a vehicle-mounted device upgrade method and a related device. The method may be applied to an intelligent vehicle, the intelligent vehicle includes a vehicle-mounted control device, and the method may include: receiving, by the vehicle-mounted control device, a first partial key sent by the communications device; restoring, by the vehicle-mounted control device, a first key by using the first partial key and a second partial key that is stored on the vehicle-mounted control device; and performing, by the vehicle-mounted control device, secure processing on a first upgrade file by using the first key, to obtain the securely processed first upgrade file, where the secure processing includes generating first message authentication code (MAC), and the securely processed first upgrade file includes the first upgrade file and the first MAC. According to this application, the vehicle-mounted device can be securely and efficiently upgraded.

Abstract: The field is related to plant breeding and methods of identifying and selecting plants with resistance to southern corn rust. Provided are methods to identify novel genes that encode proteins providing plant resistance to southern corn rust and uses thereof. These disease resistant genes are useful in the production of resistant plants through breeding, transgenic modification, or genome editing.

Abstract: An integrated thermal superconducting plate heat exchanger and a manufacturing method thereof. The integrated thermal superconducting plate heat exchanger comprises a heat exchange plate of a composite plate structure, a fluid pipe having a certain structure shape and a thermal superconducting pipe having a certain structure shape are formed in the heat exchange plate; two ends of the fluid pipe are formed with openings; and the thermal superconducting pipe is an enclosed pipe and is filled with a heat transfer working medium therein.

By combining the thermal superconducting pipe and the fluid pipe in the heat exchange plate of the integrated thermal superconducting plate heat exchanger and using features of a thermal superconducting plate such as fast heat transfer rate and good temperature uniformity, a temperature difference between the heat transfer plate and air and an effective heat transfer area are increased.
