The aging behavior of silicone rubber seals during long-term storage was studied by scanning electron microscope, attenuated total reflection-Fourier transform infrared spectroscopy, pyrolysis gas chromatography-mass spectrometry, thermogravimetric analysis and compression set test.The results show that the mechanical properties of silicone rubber
As the installation of solar-photovoltaic and wind-generation systems continue to grow, the location must be strategically selected to maintain a reliable grid.However, such strategies are commonly subject to system adequacy constraints, while system security constraints (e.g., frequency PS5 stability, voltage limits) are vaguely explored.This may
This study proposed a contribution evaluation through the independent component analysis (ICA) method.The necessity of applying ICA to the evaluation of contribution was Cadet Boots investigated through numerical simulation.Moreover, the estimation of the number of input sources, the labeling of signals, and the restoration of the signal amplitude
Abstract Polygonatum Miller belongs to the tribe Polygonateae of Asparagaceae.The horizontal creeping fleshy roots of several species in this genus serve as traditional Chinese medicine.Previous studies have mainly reported the size and gene contents of the plastomes, with little information on the comparative analysis of the plastid genomes of thi
Soil moisture is an important land environment characteristic that connects agriculture, ecology, and hydrology.Surface soil moisture (SSM) prediction can be used to plan irrigation, monitor water quality, manage water resources, and estimate agricultural production.Multi-source remote sensing is a crucial tool for assessing SSM in agricultural are
