摘要：
Single-channel densitometry methods for solids are considered in terms of the backscattering of fast monoenergetic electrons. Methods are discussed for direct density monitoring for porous materials along with a familiar integral method, which enables one to monitor indirectly the densities of some pore-free materials by measurement of the effective atomic number. An estimate is made of the effects of composition fluctuations in the solid on the direct density monitoring of porous materials by single-channel methods.
