摘要：
Possible applications of the model include the calibration and optimum design of all transmission-type alpha-particle gages for specific measurements such as atmospheric densitometers. A new gaging principle based on the alpha particle stopping power is also identified and preliminary experiments indicate its feasibility. This principle consists of using a nonlinear search on the amounts of gaseous components present to obtain the best fit between experimental and calculated alpha-particle spectra. Potential application of this principle to measurements of density (free of composition interferences) and gas composition of planetary atmospheres is discussed.
