The word 均匀性 is constructed by first combining 均 (meaning "even" or "equal") and 匀 (meaning "even" or "to make uniform") to form the adjective 均匀, meaning "uniform" or "evenly distributed". This compound is then suffixed with 性, a character used to form nouns indicating a quality or state, resulting in the noun 均匀性, meaning "uniformity" or "the quality of being even".
