Based on the analysis of discharge experiment on two-phase mixture of gas and several kinds of solid particles
it is shown that the breakdown voltage is related to polarity.Under the conditions of the negative polarity
the volume ratio makes great effect to the 50% lightning impulse discharge voltage U50
the decreased amplitude is up to about 30%.The breakdown voltage of small particles is lower than that of big particles.Under the conditions of the positive polarity
the breakdown voltage fluctuates with the change of the volume ratio
but both the volume ration and the partide size have little effects to U50.In addition
it is the same as the discharging in air
that the breakdown voltage of positive polarity is lower than that of the negative polarity in the same volume ratio.(3.
