| turbomolecular pumps | <radiobiology> Type of pumping system in which a high-speed rotor blade expels gas by physically pushing the molecules out of the vacuum chamber. These pumps overheat unless the vacuum chamber is substantially depressurised using another pumping system first. (09 Oct 1997) |
| turbot | <zoology> A large European flounder (Rhombus maximus) highly esteemed as a food fish. It often weighs from thirty to forty pounds. Its colour on the upper side is brownish with small roundish tubercles scattered over the surface. The lower, or blind, side is white. Called also bannock fluke. Any one of numerous species of flounders more or less related to the true turbots, as the American plaice, or summer flounder (see Flounder), the halibut, and the diamond flounder (Hypsopsetta guttulata) of California.
