The invention discloses a monitoring method and device for a slave core state, relates to the technical field of CPU application, provides a new monitoring method, and realizes the state monitoring of a slave core while ensuring that the performance of the CPU is not reduced. The embodiment provided by the present invention is applied to a logic device, the logic device is connected with the CPU to be tested, and at least includes a timer module in this logic device, the main core of the CPU to be tested is configured with N channels, and these channels are connected to the slave to be tested nuclear correspondence. First, set a timing period, and when the timing period expires, continuously transmit N pulses, and monitor the slave core to be tested according to the time division multiplexing principle according to the time divided by the N pulses. The technical scheme provided by the invention is mainly applied in the monitoring process of the CPU slave core.

The invention discloses a biaxial stress state test piece realized by uniaxial loading of a spherical working section. The lateral parts are symmetrical. There are spherical depressions and special-shaped holes designed on the working section; among them, the spherical depressions are designed on the front and back of the working section, located in the center of the working section; there are four special-shaped holes, which are respectively opened on the working section by its two angle bisectors on the four equally divided parts. The loading of the test piece is realized by a uniaxial fatigue testing machine. Under the designed spherical depression and special-shaped hole, a multiaxial stress state of horizontal tension and vertical compression is finally generated in the center of the entire test piece, forming a typical Tension / compression multiaxial stress state. The invention can realize the simulation of the tension and compression biaxial state at the center of the turbine disk, can partially replace the component-level assessment test, shorten the structural design period, and save the test cost.

The invention discloses an inspection system and an inspection method for one-time pressure-passing and synchronous phase verification of an electrical system. The invention belongs to the technical field of one-time pressure and simultaneous phase verification inspection of electrical systems. The system and inspection method are to carry out one-time voltage and simultaneous phase verification inspection before the electrical system is powered, so as to ensure that the electrical system is synchronized with the power supply and operates normally.
