| Zusammenfassung: | The embodiment of the invention provides a surface density measuring method and device, the device comprises a transmitting end array, a receiving end array, a controller and an upper computer, and the method comprises the steps that the transmitting end array transmits initial ultrasonic waves to materials; the receiving end array receives the target ultrasonic wave penetrating through the material, converts the target ultrasonic wave into an electric signal and sends the electric signal to the controller; the controller performs protocol conversion on the electric signal to obtain protocol data, and sends the protocol data to an upper computer; and the upper computer determines the surface density based on the protocol data. Initial ultrasonic waves are transmitted to the materials through the transmitting end array; the receiving end array receives the target ultrasonic wave penetrating through the material, converts the target ultrasonic wave into an electric signal and sends the electric signal to the co |
