Abstract: A cross-blockchain data processing method is provided. The method includes: obtaining an asset transfer instruction triggered for a first asset on the first blockchain, and configuring an asset state of the first asset to a locked state on the first blockchain; determining the first asset in the locked state as an asset, and determining a cross-chain asset transfer request corresponding to the asset; obtaining an asset transfer interface associated with a second blockchain, and calling the asset transfer interface to transmit the cross-chain asset transfer request to a second server node on the second blockchain; and receiving signing response information transmitted by the second server node in response to determining that the verification succeeds, freezing the asset on the first blockchain according to the signing response information, and notifying the second server node to release a second asset associated with the asset on the second blockchain.

Abstract: Provided are a method and system for detecting an oil abrasive particle size. The method includes: acquiring a voltage signal of an oil abrasive particle in real time, where the voltage signal is generated in real time in a process that the oil abrasive particle passes through an electromagnetic abrasive particle sensor; establishing a voltage curve coordinate system with an amplitude of the voltage signal as a Y-axis and a time of the voltage signal as an X-axis, and obtaining a voltage curve; performing feature extraction on the voltage curve, and obtaining an area S defined by a voltage curve within a half voltage signal cycle T and the X-axis and a maximum absolute value A of a voltage signal value according to the voltage curve coordinate system; and inputting S and A to a trained back propagation neural network for prediction to obtain a predicted oil abrasive particle size.
