2.The kinetic equation is rC = k CACB, the apparent activation energy is 61.4 kJ/mol, and the reaction rate constant k=1.36107 exp(7380/T) [L2/(m2.min.mol)].
3.According to Cassie-Mayr equation, commutating circuit equation and stability decision theory, the calculation formulae of critical arc time constant c, critical resistance Rc, escalation rate of the oscillation current S and the optimal inductance Lopm are deduced.
