In this work, a wireless passive LC resonant sensor based on DuPont 951 ceramic is proposed and tested in developed high-temperature/pressure complex environment. The test results show that the measured frequency varies approximately linearly with applied pressure; simultaneously, high temperature causes pressure signal drift changes response sensitivity. Through theoretical analysis of structure model, it found increase dielectric constant decrease Young's modulus are main affect...

Soil carbon content and stability are primarily influenced by the stabilization of particulate organic matter (POM) mineral-associated (MAOM). Despite extensive research on processes POM MAOM components under various land-use types, investigation into soil remains limited in saline–alkali soils. Therefore, we collected samples from different positions drainage ditches at four reclamation times (the first, seventh, fifteenth, thirtieth year) to determine their physicochemical properties....
