The invention provides a mining area ground surface coverage change and subsidence area monitoring system. The system comprises a rainfall monitoring module, a GPS settlement monitoring module, a communication module and a monitoring center. The rainfall monitoring module is used for collecting mining area rainfall information; the GPS settlement monitoring module is used for acquiring surface displacement information of a crack body; the communication module is used for sending the collected rainfall information and the crack body surface displacement information to a monitoring center; the monitoring center is used for storing and analyzing the data and automatically mapping and displaying the data in an animation manner; the rainfall information of the mining area comprises rainfall rate, hourly rainfall and daily rainfall; the crack body surface displacement information comprises daily average displacement rate, displacement direction and accumulated displacement. By means of the system, real-time collection of the rainfall and the crack body surface displacement of the mining area is achieved, and the safety state of overall operation of the mining area is mastered in real time.

This invention belongs to the field of biomedicine, and specifically relates to the application of FeTMPyP in the preparation of drugs to alleviate ovarian toxicity. This application addresses the issue that combined exposure to MC-LR and NaNO₂ significantly induces nitrification stress in mouse ovaries, leading to follicular barrier disruption and ovarian reproductive endocrine dysfunction. FeTMPyP was selected as an intervention agent, which effectively alleviated nitrification stress induced by combined exposure to MC-LR and NaNO₂ in mouse ovaries, and improved sex hormone disorders, estrous cycle irregularities, and follicular atresia caused by the combined exposure to these two toxins. Simultaneously, it restored the fertility of mice, indicating that FeTMPyP intervention can alleviate ovarian toxicity induced by combined exposure to MC-LR and NaNO₂ in mice. This invention can be used to prepare drugs to prevent and treat diseases related to ovarian toxicity caused by environmental toxin exposure in mice, providing a new approach for the early identification and targeted intervention of ovarian-related diseases.

This invention discloses a HAP-ANF composite separator, its preparation method, and its applications, belonging to the fields of polymer fibers and lithium-ion batteries. The HAP-ANF composite separator is produced by mixing aramid nanofibers and hydroxyapatite nanofibers using a wet papermaking process. The production process is simple and feasible, avoiding problems such as loose paper structure, poor interfacial bonding, and low mechanical and compressive strength caused by the large dimensional differences in aramid separator paper components. The prepared HAP-ANF composite separator has high temperature resistance and flame retardancy, effectively improving battery safety and stability. It can be used to manufacture thinner, lighter, and more compact high-capacity batteries, offering significant development opportunities in the new energy and high-end consumer goods sectors, thus achieving higher-quality development in the aramid fiber industry.

This utility model relates to a multifunctional chassis test bench, including a frame module and a wheel system module. The frame module is equipped with a power supply module, a load platform module, and a control system. A torque sensor is mounted on the drive shaft of the wheel system module. The frame module includes a skeleton body, a wheelbase adjustment device, and a track width adjustment device. A wheel system module is located on each side of the track width adjustment device. The load platform module, from bottom to top, includes a base plate, a six-degree-of-freedom platform, and a load hopper. The load hopper contains load weights of various specifications, and a pressure sensor is embedded in the six-degree-of-freedom platform. This application is widely adaptable to various chassis and wheel systems of different specifications, enabling arbitrary adjustment of test track width and wheelbase. Through the load weights in the six-degree-of-freedom platform and load hopper, the rotational speed and torque of each wheel under different center-of-gravity layouts can be fed back, providing comprehensive, accurate, and timely theoretical and experimental data for chassis optimization design and new chassis development, thus improving the versatility and test function diversity of the test bench.
