Real-time monitoring of wire rope tension is of great significance to the safe operation of mine hoist.Due to the longitudinal and lateral coupling vibration of wire ropes during the operation of hoist, there are high Fish Food frequency components in measured tension signals of wire ropes, which cannot effectively characterize the actual lifting l
With the advantages of large transmission capacity, low losses, rapid and flexible power regulation, and the ability to achieve non-synchronous networking, High Voltage Direct Current transmission systems are playing an increasingly important role in long distance transmission and grid interconnection.However, under certain circumstances, such as d
Heavy metal pollution in soil is becoming more and more serious.LIBS is one of the most promising technologies for Westerns Bit rapid detection of heavy metal contamination in soil.However, due to the wide variety of soils and complex matrices, accurate quantification remains a challenge.In total, 451 soil samples were prepared and detected by the
The effects of the beach community structure of macro- and meiofauna on the process of beach wrack decay were investigated by means of a simple field colonisation experiment in a temperate, fine quartz sediment, sandy Tote Bag beach at the end of the Hel Peninsula in Poland.1260 replicate litterbags of three mesh sizes (12 mm, 0.5 mm, 48 µm) c
