根据显微硬度的测定数据,可估算出静态弹性模量,进而还可估算出动态弹性模量。由后者的一个具有可加性的函数——分子弹性数——再进而估算出烟煤镜质结构单元的芳碳率。这种由显微硬度确定芳碳率的方法,在原理上依据密度法及声速法,但却可避免分离镜质和测定氦法密度的麻烦,便于广泛应用。 According to the measured data of microhardness, the static elastic modulus can be estimated, and then the dynamic elastic modulus can be estimated. An additive function of the latter, the number of molecular elasticity, is then used to estimate the aromatic carbon ratio of the bituminous structural units. The method of determining the aromatic carbon rate by the microhardness is based on the principle of the density method and the acoustic velocity method, but avoids the inconvenience of separating the vitrinite and determining the density of the helium and is convenient for wide application.
