The present invention provides a method for calculating the secrecy capacity of a dual-media untrusted relay system and an optimization method to solve the problem of calculating the average secrecy capacity and security performance of a series-parallel hybrid fading system with variable gain untrusted relays optimization problem. In the confidentiality calculation method, communication is established between the source S, the untrusted relay R, and the terminal D, and S sends useful information and interference signals to act on R and D respectively during the broadcast stage, and D can eliminate the interference signals, thereby Calculate the average secrecy capacity of the system for the model; the optimization method optimizes the allocation of system resources among the transmitting power, artificial noise power and untrustworthy relay power by solving the nonlinear multivariate function, and balances the system security and reliability performance . The invention deduces the calculation formula of the average secrecy capacity, and at the same time establishes a mathematical model to optimize the allocation of system power resources, improves the reliability of the relay network, and optimizes the security and secrecy performance at the same time.

The invention discloses an eddy current detection method and device using finger touch as an auxiliary means. The coil that can be used to realize the eddy current detection is wound into a pancake shape or made on a flexible circuit board to form a small flexible sensor, and then Install the small sensor on the finger of the human body (that is, the operator). The finger is equivalent to the skeleton of the coil. Since the small sensor can be flexibly bent, the small sensor can be adapted to the surface of the metal structure with the soft movement of the finger surface. At the same time, using the sensitivity of human touch and the flexibility of fingers, it can easily move on the tested surface of metal structural parts, without being affected by various obstacles such as depressions and welding bumps, and can use the tactile sense of fingers to assist Positioning and judgment to improve the accuracy and adaptability of the detection results, this method is especially suitable for the detection of defects on the complex surface of metal structural parts.
