Method and system for preparing liquid drops through focused ultrasound, detection equipment and storage medium

The invention provides a method and a system for preparing uniform and stable micro-droplets by using focused ultrasound, detection equipment and a storage medium. The method comprises the following steps: preparing a sample, a fluorinated oil phase substance, a temperature control environment and an adjustable ultrasonic environment; performing uniform and stable cooling pretreatment on the sample, so that the sample is in a low-temperature state lower than room temperature; adding a fluorinated oil phase substance into the pretreated low-temperature state sample and carrying out dispersion treatment; a high-frequency short-wave focusing sound field is formed by setting parameters of an ultrasonic forming device, a sample is placed in an ultrasonic gathering area in an ultrasonic environment with the duty ratio of 200/500 through a suspended container, a sample solution is rapidly heated in the ultrasonic focusing environment, and uniform and stable micro-droplets containing a water-in-oil phase are formed a
