Claim 6:
7. The device for separating sub-micron particles in the air according to claim 1, wherein: when the standing wave amplitude of the second standing wave field is maintained unchanged, the length of the second separation channel is positively correlated with the mean flow velocity of the particles flowing in the second separation channel;
when the mean flow velocity of the particles flowing in the second separation channel is maintained unchanged, the length of the second separation channel is negatively correlated with the standing wave amplitude of the second standing wave field; and
when the length of the second separation channel is maintained unchanged, the standing wave amplitude of the second standing wave field is positively correlated with the mean flow velocity of the particles flowing in the second separation channel.
