Between space formed droplet floating zone 7.Here with supersonic wave suspended technology, i.e. acoustic levitation technique, different according to principle
Standing wave suspension technology (Standing Wave Levitation) and near field suspension technology (Near Field can be divided into
Levitation), the present invention specifically uses standing wave suspension technology.Standing wave suspend be utilize at ultrasonic transducer radiating surface and
The high intense standing wave field of reflecting surface intermediate formation realizes the suspension of small particle body.Except driving electricity in standing wave suspension system
Outside source, supersonic signal generator 5, transmitting terminal 1, also need to add a reflection end 2 at end so that ultrasound wave can be reflected back
Go.When distance between reflection end 2 and transmitting terminal 1 is the integral multiple of 1/2 wavelength, the ultrasound wave that transmitting terminal 1 is launched, with
The ultrasound wave that reflection end 2 reflects back can be overlapped mutually formation standing wave.At the node of standing wave, both sides acoustic pressure is in opposite direction, sound
Pressure acts on the object in ultrasonic standing wave sound field, just can realize levitated object suspension at node.Levitated object can in theory

Under saturation vapour pressure, e is the actual water vapor pressure that water surface air is current；P is current gas pressure.
In addition:
E=esw·RH
In formula, RH is relative humidity.
Comprehensive three above formula, it can be deduced that evaporation rate is:
Therefore, evaporation rate is directly proportional to wind speed, temperature, gentle with relative humidity is pressed into inverse ratio.
