STAND FOR PHYSICAL MODELLING bubble conduction of gases to the water environment and bottom sediments (OPTIONS)

摘要

Stand for artificial reproduction processes bubble transfer gas in water bottom sediments of various types and emanation process gas from the sediments into the aqueous layer, and can be used to develop acoustic gas amount estimation methods entering the water from precipitation during nucleate transference and study of the formation and decomposition of gas hydrates in the bottom sediments of different types. The stand consists of a supporting frame in the form of a rectangular parallelepiped, inside which the gas flow control system, surveillance system, a light diffusing screen and the container bottom sediments. gas flow control system includes serially connected gas source, a remotely controlled gas valve and a gas atomizer. Video surveillance system includes a remotely controlled video camera mounted on a platform capable of tilting and illuminators. A video camera illuminators and the gas dispenser are movable within a frame. container wall facing to the camcorder, is transparent, and a light diffusing screen is secured over the container before the illuminators. 2 n.p.f.
