A pair of parallel guide rods is horizontally connected between the top ends of piston rods of the two air cylinders. According to the aluminum metal sawing machine tool, through the pressing mode that the pressing plates are inserted into the two sides of the thin-wall aluminum pipe to enable the pressing belts to be pressed on the peripheral wall of the aluminum pipe in a sleeving mode, stress points of the thin-wall aluminum pipe are increased and distributed more evenly, and the pressed contact area of the peripheral wall of the thin-wall aluminum pipe is obviously increased compared with an original rubber pad; the upper limit of fastening pressure borne by the thin-wall aluminum pipe is improved, the thin-wall aluminum pipe is stable and not prone to deformation in the cutting process, the clamping distances of the multiple clamping positions can be uniformly and rapidly adjusted, and the thin-wall aluminum pipes with different pipe diameters can be rapidly assembled.

An adversarial training method based on joint label smoothing can train a neural network model capable of resisting different attack perturbation sizes during the training process. The model can identify the existence of adversarial samples under large perturbation attacks and reject their output results, and can correctly identify the true category of samples under small perturbation attacks.

The invention relates to the technical field of electric connector manufacturing, in particular to a lifting and closing type FPC connector. And the wiring terminal and the mechanical terminal are independent from each other and are insulated from each other. The plurality of mechanical terminals cooperate to elastically apply pressure and limit the overturning pressure applying piece. And under the condition that the overturning pressure applying piece is locked, the flexible flat cable is elastically pressed and contacted by the plurality of wiring terminals in a cooperative manner and is electrically conducted. And the turnover pressing piece is formed by combining a plastic turnover pressing plate and a metal shell. The left metal locking piece and the right metal locking piece cooperate to bear and lock the overturning pressure applying piece. The left metal locking piece and the right metal locking piece are grounded, the metal shell which is electrically conducted with the left metal locking piece and the right metal locking piece at the same time is indirectly grounded, and at least one of the multiple wiring terminals and the multiple mechanical terminals are grounded. Therefore, not only is the signal transmission process prevented from being affected by adverse effects of electromagnetic waves and noise ensured, but also the overturning pressure applying piece is always kept in a reliable locking state in the signal transmission process.

The embodiments of the present disclosure disclose a method and device for integrating a cross-platform mobile application development framework. A specific implementation of the method includes: creating an independent cross-platform mobile application development framework process for the cross-platform mobile application development framework program; the main process of the Android application provides an API for the cross-platform mobile application development framework process, and uses a combination of the cross-process communication technology in Android and the internal communication technology of the cross-platform mobile application development framework to achieve communication between the two processes. This implementation method can completely isolate the cross-platform mobile application development framework from the host, and the crash of the cross-platform mobile application development framework will not affect the stability of the host. The host can monitor the cross-platform mobile application development framework program and can actively kill (or restart) the cross-platform mobile application development framework program. Increase the memory limit of the cross-platform mobile application development framework. When the cross-platform mobile application development framework program freezes, the host can detect it and handle it in time.
