The invention belongs to the technical field of concrete durability monitoring. The invention particularly relates to an ECT sensor structure optimization and electromagnetic field analysis method. The technological process comprises eight steps including parameter setting, geometric setting, material setting, mesh generation, physical field setting, solving, sensor structure optimization and electromagnetic field distribution calculation. A new idea is provided for solving the positive problem of an ECT system based on software COMSOL. After modeling is completed, the uniformity degree of thesensitive field of an ECT sensor is analyzed through a calculation result, structure parameter values of all parts of the ECT sensor are adjusted, an optimal design scheme is searched for, meanwhile,change of the internal electromagnetic field when a concrete structure contains water can be visually and clearly observed, the relation between the internal moisture content of the concrete structure and the relative dielectric constant is obtained, the accuracy of imaging the internal moisture content of the concrete structure through the ECT technology is improved, and a new verification method is provided for the durability test of the concrete structure.

The invention relates to a method and system for processing communication network call information in the field of mobile communication, in particular to a method and system for analyzing abnormal call events of users and performing real-time monitoring and optimization of the network. The network element records the call information of each call-related stage, reports the abnormal call information to the call history record server, and stores it in the database of the call history record server; the abnormal call information is processed by the network management system. The present invention can carry out end-to-end comprehensive analysis of the whole network element for a user's call; it can not only reflect the operation status of the network based on the network element, but also reflect the specific details of each abnormal call; at the same time, the analysis cost is greatly reduced, and the result is clear Intuitive, adaptable to large-scale network environment and multi-vendor network operation environment.

The invention belongs to the field of oil and natural gas industry oil casing thread parameter detection, and particularly relates to a method for judging the angle of an oil casing knuckle thread form. The method comprises the following steps that (1) after casing thread machining is completed, a thread form height deviation value h is measured; (2) a judging criteria is set to be h<k(H-Ss-(p / 2) / tan(A / 2)); and (3) when the measured thread form height deviation value h meets the judging criteria, the angle of the thread form is judged to be qualified, otherwise, the angle of the thread form isjudged to be unqualified. According to the method for judging the angle of the oil casing knuckle thread form, the judging range is obtained through mathematic model calculation, judging is conductedby comparing the measurement value with the judging range, the result is intuitive and clear, and the detection efficiency is high.
