Abstract: Disclosed is a damping test system for a wood-based material based on full sampling of a free vibration curve, comprising: a damping test device, a carrying space, a processor, and a storage module. The processor is configured to generate a test scheme and execute a test corresponding to the test scheme; obtain a labeled test scheme; determine, based on the labeled test scheme, test data of the labeled test scheme; determine, based on the test data, whether an extended test is added; in response to determining that the extended test is added, adjust, based on the test data obtained from the storage module, a sampling frequency of a data monitoring module, and determine a test parameter of a newly added extended test; generate, based on the test parameter of the newly added extended test and an adjusted sampling frequency, a new test scheme.

Abstract: A control method and system of neutral section passing of multi-locomotive short broke trains. Distance traveled by a train after a primary multiple unit enters a neutral section is calculated in real time, so that a neutral section passing procedure of a secondary multiple unit is effectively controlled, thereby solving the problem that when the multi-locomotive short broke trains operate with double-raised pantographs, if the distance between the two pantographs is shorter than the length of a neutral zone of a neutral section and longer than the length of a no-electricity zone of the neutral section, when the two pantographs pass through the neutral sections, the two pantographs will span the two neutral sections and generate an interphase short circuit. The method improves safety of the EMU when it passing neutral section and ensure that the EMU can reliably pass through the neutral section with double-raised pantographs.

Abstract: There are provided a power supply system for a diesel multiple-unit train, a diesel multiple-unit train including the power supply system, and a traction control method for a diesel multiple-unit train. The power supply system includes: a diesel power pack, a traction inverter connected to a traction motor, and an auxiliary inverter connected to a train load. The power supply system further includes a direct current chopper and a supercapacitor. A high-voltage side of the direct current chopper is connected to the diesel power pack, and a low-voltage side of the direct current chopper is connected to the supercapacitor. The supercapacitor is connected to the traction inverter and the train load.

Abstract: Provided are a method of assisting monitoring alarm method and a medical external equipment and a medical host equipment using the method. A technical scheme thereof comprises connecting the medical external equipment with the medical host equipment through an interface, wherein the medical external equipment forms a plug-and-play external alarm equipment. The medical host equipment performs self-check, and sends an alarm information to an auxiliary alarm device of the medical external equipment and generates a corresponding alarm when an alarm device in the medical host equipment works abnormally, thereby reducing a risk to the medical host equipment in the situation that the alarm device in the medical host equipment is in failure.
