This application relates to a method, system, electronic device, and storage medium for early warning of acute mountain sickness. The method includes: collecting physiological data from a step test conducted on a subject at a target plain altitude; generating at least one physiological principal component based on the step test data; performing cluster analysis on the at least one physiological principal component to obtain risk classification clusters; obtaining the actual high-altitude Lake Louise score of the subject in each risk classification cluster and calculating the score interval proportion to determine the risk classification label; and providing an early warning of acute mountain sickness to the user based on the risk classification label. This solves the problems in related technologies, such as high dependence on specialized testing equipment and laboratories, time-consuming testing processes, inability to screen individuals before they enter high altitudes, difficulty in achieving non-invasive and simple screening, and inability to effectively determine the acute mountain sickness tolerance of new subjects, thus hindering personalized early warning and prevention.

The utility model discloses a polymer nanometer reinforced rubber strip strength test equipment after forming, it includes base, tow end, clamping end, tensile testing machine, removal structure, the one end of rubber strip that clamping end clamps, the tow end is used for clamping and through removal structure tow rubber strip's other end removal, forms the pulling of rubber strip, when pulling, through tensile testing machine tensile testing machine test tension, clamping end includes tray, and the tray is installed with carousel, and the motor is installed in the tray, and the drive end of motor is connected with carousel, and the sleeve is installed on carousel, still install two symmetrical clamping plates on the tray, and two clamping plates are connected with the pneumatic cylinder respectively. The test equipment in the utility model can test directly from the rubber strip of winding, need not cut a section in advance to test, and simultaneously, can carry out step -by -step test to every section of the rubber strip of winding, after testing, and let rubber strip keep winding, can improve test efficiency.

The application discloses an aerogel thermal stability test system and a test method thereof, and belongs to the technical field of aerogel testing. The system comprises a test table and a control seat. An insulation groove for testing the thermal stability of aerogel is arranged at the top of the test table. A heating seat is fixedly connected to the inner side wall of the insulation groove. A test frame is connected to the top of the heating seat through a heat conduction plate. The piston plate is used to drive the oxygen supply through the downward pressing action, so that the mechanical pressure and the flame combustion are coupled in the physical mechanism. Not only the additional control gas circuit is saved, but also the real physical process of "pressure leading to structural deformation, and then affecting the flame impact effect" is simulated. The fire test under dynamic pressure is realized. The key working condition which is difficult to simulate in static or step-by-step test is realized. The protective performance of the material in the extreme dynamic event can be more truly evaluated.
