    摘要: A nitrogen oxides decreasing combustion method which comprises; a first step of mixing a fuel and air with each other; a second step of bringing the mixture obtained in the first step, into contact with a packed catalyst so as to cause a portion of the mixture to burn only through a catalytic reaction; and a third step of adding a fresh supply of the fuel to a stream obtained from the second step to form a mixed gas and causing the mixed gas to undergo non-catalytic thermal combustion; the temperature of said packed catalyst being lower than the ignition temperature of the mixture and the adiabatic flame temperature of said mixed gas being lower than a temperature at which the nitrogen oxides occur.

    摘要: A halogen ion concentration in a solution is measured by bringing halogen ion-selective detection means comprising a silver/silver halide electrode, and a reference electrode into a solution whose halogen ion concentration is to be measured, and measuring an electromotive force of the halogen ion-selective detection means in the presence of silver ions dissolved in the solution. The electromotive force corresponds to the halogen ion concentration in the solution.
