The present invention provides a soluble T cell receptor, which comprises all for part of a TCR \u03b1 chain, except the transmembrane domain thereof, and all or part of a TCR \u03b2 chain, except the transmembrane domain thereof. The invention is also directed to a process for the desorption of the gaseous components from the liquid absorbent, as well an apparatus for the separation of the gaseous component and an apparatus for the desorption of the gaseous component. Further movement of the priming piston forces air from the housing into a fuel bowl, thereby pressurizing the fuel bowl and causing fuel to move from the fuel bowl into the throat of the carburetor. The second modem activates the second codec unit if the data processing order is inputted and controls the second codec unit to process data corresponding to the data processing order. 05, and total light transmittance is greater than or equal to 92%.
