Seasonal variations of soil water vapor distribution transport and phase transition in the loess unsaturated zone from fixed volume monitoring

Abstract Water vapor is a crucial yet often overlooked water resource in the soil’s unsaturated zone of arid and semi-arid regions. Understanding water vapor behavior in the soil’s unsaturated zone is crucial for research on soil and energy balance, vegetation water stress, and w...

Analysis of mid-infrared spectral characteristics and recognition models of coal with different particle sizes

As a core energy source, the accurate identification of coal particle size is a critical part in the quality control of raw coal mining, separation and processing, storage and transportation, and quality upgrading. The differences in physical and chemical properties of coal with...
