Record Label : mass_fraction_of_hox_expressed_as_hydrogen_in_air
Record Title : Mass Fraction of Hox Expressed As Hydrogen in Air
CF Standard Name : mass_fraction_of_hox_expressed_as_hydrogen_in_air
Record Description : "Mass fraction" is used in the construction "mass_fraction_of_X_in_Y", where X is a material constituent of Y. It means the ratio of the mass of X to the mass of Y (including X). A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The phrase "expressed_as" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A. "HOx" means a combination of two radical species containing hydrogen and oxygen, OH and HO2.
