Abstract: An alarm analysis method, including determining M alarm pairs in a first alarm set, where each alarm pair of the M alarm pairs includes a first alarm and a second alarm having an association, generating, according to an association rule, a first feature set of N alarm pairs, the first alarm of each alarm pair of the N alarm pairs being an alarm pair root in the first feature set, the first feature set including a first probability that a first subsystem to which each first alarm belongs is a subsystem root and a first alarm object is an alarm object root and a second probability that a second subsystem to which each second alarm belongs is a subsystem root and a second alarm object is an alarm object root, and determining root information of the first alarm set based on the first probability and the second probability.

Abstract: A composite vortex reactor comprises a Rankine cyclone reactor and a Taylor vortex reactor. The Rankine cyclone reactor comprises a reaction chamber, a side wall of the reaction chamber is provided with a first inlet pipe and a second inlet pipe, and fluids entering the reaction chamber through the first inlet pipe and the second inlet pipe can form a gyro-fluid in the reaction chamber, and the middle of the top of the reaction chamber is provided with a gyroscopic outlet pipe. The Taylor vortex reactor comprises an inner cylinder and an outer cylinder which are coaxially provided, the inner cylinder is driven by a rotary driving device to rotate, an annular reaction space is formed between the inner cylinder and the outer cylinder. The upper end of the outer cylinder is provided with a reaction outlet pipe communicating with an upper portion of the annular reaction space.
