Suitable air humidity is of great importance for human health, crop growth and the life of buildings. In this work, the polyvinylidene fluoride/calcium chloride (PVDF/CaCl2) porous membranes with rich pore structures for adsorption of high‐humidity gases were prepared using solvent evaporation‐induced phase separation. The results showed that the gap between the PVDF spherical crystals increased...
This paper does a detailed depiction and analysis on the aircraft two-level maintenance (TLM), and then discusses the general TLM process and related elements separately; Constructs a general TLM process model as well as a simulation framework based on the boundary limits and parameter index system analysis. The model can be used for TLM process simulation and evaluation through computer simulation,...
