relative density

  • 1. 

    N the ratio of the density of a substance to the density of a standard substance under specified conditions. For liquids and solids the standard is usually water at 4°C or some other specified temperature. For gases the standard is often air or hydrogen at the same temperature and pressure as the substance 相对密度 ( symbol: ) → see also specific gravity, vapour density
