The ratio of released coefficient is identified with spectral intensities measured by a spectroscope. This time by using this character, the temperature of the plasma in Ar at 0.1 Mpa was evaluated by the ratio of the released coefficient to be 10,500K at 100A. The electron density was measured by the Stark method to be 1.44 × 1023m−3 at 100A. The temperature and electron density are roughly constant regardless of arc current between 50–100 A. The composition of particles was evaluated by using three equations such as Saha equation, state equation and the condition that charges are neutral. In result when the temperature is 10,500K, most of tungsten atoms are ionized. But most of Argon ones are not ionized because the ionization energy of tungsten is much lower than that of Argon., 【査読有】}, pages = {11--20}, title = {スペクトル放出係数の比から求めた Ar アークプラズマの粒子組成}, volume = {8}, year = {2003}, yomi = {ミズノ, ジンイチ and イノウエ, ユキエ and イワオ, トオル and イナバ, ツギノリ} }
