Net buoyancy changes affect hovering performance and increase the extra energy consumption of deep-sea intelligent floats (DIFs) at different submergence depths. To improve the adjustment efficiency of net buoyancy changes and solve the extra energy consumption problem at different submergence depths. this study proposes a combination model of ballasting weight (BW) and minimum oil co... https://www.inmuebleslasmercedes.com/product-category/martini-glasses/
