This invention provides a limestone thermal burst monitoring system and method based on 3D-DIC and acoustic emission, relating to the technical field of high-temperature rock testing technology. The method includes: acquiring acoustic emission signals of a limestone sample under thermo-mechanical coupling loading; generating a hard trigger pulse when the acoustic emission signal in any channel meets a preset trigger condition, and recording the arrival time of the acoustic emission signal meeting the preset trigger condition to determine an arrival time set; and controlling a high-speed camera group to freeze and save the image sequence based on the hard trigger pulse. This invention solves the problem of low accuracy in limestone testing and monitoring, thereby improving the accuracy of limestone testing and monitoring.

This invention discloses a method and system for measuring soil moisture content during garden maintenance, relating to the field of data processing technology. It addresses the problem of insufficient accuracy in soil moisture content measurement results during garden maintenance. The method includes: acquiring monitoring data from multiple monitoring points in the garden; determining the co-occurring abnormal period for each monitoring point based on the monitoring data from each point; determining the state recovery rate for each monitoring point based on the monitoring data during the co-occurring abnormal period; for each monitoring point, determining the disturbance value of the dielectric constant during the co-occurring abnormal period based on the co-occurring abnormal period, the state recovery rate, the correlation between various monitoring indicators during the co-occurring abnormal period, and the correlation between various monitoring indicators during non-co-occurring abnormal periods; and determining the soil moisture content of the garden based on the disturbance value of the dielectric constant and the spatial relationship between multiple monitoring points.

The present application relates to the technical field of micro-ecological diagnosis and treatment, and is a multi-chamber different point intestinal flora collection device, comprising a shell, a driving switching module and a plurality of circumferentially distributed sampling shells. The shell is designed in a split type, facilitating sample recovery; each sampling shell inlet is covered with a slow-release layer with different dissolution characteristics, which can respond to specific environmental parameters of different sections of the intestine. After a slow-release layer in the target intestinal section dissolves to trigger single-point sampling, the sampling shell is automatically driven to switch, allowing the next sampling shell to enter the working position. The device realizes automatic, time-sequential and multi-point precise sampling in a single intestinal journey, ensures independent and non-cross-contaminated samples at each point, and can obtain in-situ liquid samples at multiple points in the intestine, truly reflecting the spatial distribution heterogeneity and dynamic change rule of the flora, and providing key technical support for intestinal micro-ecological research, disease diagnosis and personalized treatment.
