In the method of measuring a mixing ratio of a mixture, a mixture consisting of two kinds of substances with different emissivities is measured for a temperature change when the mixture is heated, and a mass mixing ratio of the mixture is calculated by using: an average thermal diffusivity of the mixture obtained from heat transfer analysis of the measurement result; and each thermal diffusivity of the two kinds of substances.例文帳に追加

熱拡散率が異なる２種類の物質からなる混合物について、前記混合物を加熱した際の温度変化を計測し、該計測結果の伝熱解析により得られる前記混合物の平均熱拡散率と、前記２種類の物質の各々の熱拡散率とを用いて、前記混合物の質量混合率を算出することを特徴とする混合物の混合率計測方法を用いる。 - 特許庁
