The invention belongs to the technical field of resource regeneration and utilization, and provides a high-activity calcium hydroxide desulfurized fly ash resource regeneration and cyclic utilization method, which comprises the following steps: carrying out granularity division detection on calcium carbonate after solid-liquid separation, marking a calcium carbonate detection sample through granularity detection, and detecting the granularity of the calcium carbonate detection sample; the solid-liquid separation quality is judged by analyzing the number and particle size deviation of the marked unqualified detection samples and combining the particle size uniformity of the qualified detection samples, a solid-liquid separation curve is constructed by obtaining the rotating speed and the solid-liquid separation value of a centrifugal machine in multiple historical solid-liquid separation operations, change analysis is conducted, and the solid-liquid separation quality is judged. And whether the rotating speed of the centrifugal machine can influence the solid-liquid separation quality or not during solid-liquid separation is judged, and if yes, the optimal rotating speed value is obtained, solid-liquid separation is conducted again, optimization operation of follow-up solid-liquid separation is facilitated, and the calcium hydroxide desulfurized ash resource regeneration cycle efficiency is improved.

A direct current transmission line protection method, system, medium and device are disclosed, the method comprising: obtaining a calculated voltage and a measured voltage at a first measurement point and a second measurement point of a direct current transmission line; determining a first similarity corresponding to the first measurement point and a second similarity corresponding to the second measurement point according to the calculated voltage and the measured voltage; determining a first fault direction corresponding to the first measurement point and a second fault direction corresponding to the second measurement point according to the first similarity and the second similarity respectively; determining a fault type based on the first fault direction and the second fault direction. The application determines the fault direction of the line fault based on the similarity between the calculated voltage and the measured voltage, and determines whether the line has an internal fault based on the fault direction, which can be used as a backup protection for the direct current transmission line in different structures of the direct current power grid, and has good rapidity and sensitivity.

This application provides a method, apparatus, computer equipment, and storage medium for velocity processing of seismic data, belonging to the field of seismic data processing technology. The method performs stacking velocity analysis on P-wave seismic data from seabed nodes to obtain the optimal P-wave stacking velocity and P-wave anisotropy parameters under two reference planes. These are then converted to a unified reference plane, and velocity migration is performed based on the pre-stack time migration velocity parameters of the P-waves under both reference planes. This fully considers the differences in conditions between acquiring P-wave seismic data from seabed nodes and land nodes, resulting in accurate velocity analysis results and improving the accuracy of seismic data velocity processing.
