How Does Fluid Exchange Between Pores in Unsaturated Porous Media?
Abstract The inter‐pore fluid exchange, driven by molecular diffusion, is referred to as pore coupling. The pore coupling affects subsurface pore‐scale physicochemical dynamics. Monitoring pore coupling is essential for understanding numerous hydrological and ecological processes.

Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters
Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.
