(알루미늄 용탕에서 수소 가스 분석기)

     1.  이론(thery)

     Sievert's low에 기초로하여 합금조성을 계산하는 동안 용탕 온도를 측정하고 수소가스량을 계산하게 된다.  Sivert's low는 아래와 같다.

    Sivert's low  :  Log C_H = 0.5*log_pH2 - A/T+B

    여기서  C_H  : concentration of hydrogen dissolved in aluminum in cm³/100g

                PH2 : partial pressure of the hydrogen in mbar

                T : melting temperature in K

                A, B  :  Sivert's constants depend on the concentration of the alloy
