Determination of Thermodynamic Properties from the Experimental , Relationships,res and temperatures of an increasing range and with accuracies that tax the state of the art. In recent years these needs have been accelerated by the tremendous worldwide effort in the field of space exploration.

Von der Suchtprävention zur Drogenmündigkeitzation gages. None of these gages has been developed to the point where it is a serious competitor to the ionization gage at pressures below 10. Torr, nor have the operational problems of these gages been clearly established. This chapter will concentrate its attention on ionization gages with only very brief reference to other types.

Part 2. Pressure Scale and Fixed Point,ich experiences a phase change at some known pressure and noting the load at this change. This gives a point on the load pressure calibration curve. Several such points are measured and then connected with a smooth curve. Of course, the above presupposes that there has been a measurement of the pressure at which these phase changes take place.

None of these gages has been developed to the point where it is a serious competitor to the ionization gage at pressures below 10. Torr, nor have the operational problems of these gages been clearly established. This chapter will concentrate its attention on ionization gages with only very brief reference to other types.

Part 3. Piston Gages,d to cover the pressure range of interest for industrial applications. In 1846 the German railway engineer Schinz. had discovered that a curved tube of elliptical cross section would change its curvature when subjected to internal pressure and by 1848 steam pressure gages based on this principle wer
