摘要： The present disclosure provides an aerosol generation system, a measurement method, an atomization device, and a power supply device. The aerosol generation system comprises: a liquid storage cavity, a vaporization element, a battery cell providing a power to the vaporization element, an air flow sensor for measuring an air flow inhalation velocity, and a controller. The controller is configured to determine the consumption of a liquid matrix in a time period on the basis of the power applied to the vaporization element, the air flow velocity, a correlation coefficient between the amount of aerosol generated and the power applied to the vaporization element, and a correction constant between the amount of aerosol generated and the air flow velocity in the time period. The use of the aerosol generation system can accurately estimate, measure, and/or predict the amount of the aerosol or the liquid matrix material delivered to a user.
