Abstract: The embodiment of the present disclosure provides an imaging method for a dispersion energy spectrum of surface waves, an electronic device, and a storage medium. The imaging method includes: obtaining first surface wave data, and the first surface wave data corresponding to a space-time domain representation; processing the first surface wave data to obtain the second surface wave data, and the second surface wave data corresponding to a space-frequency domain representation; and processing the second surface wave data based on a preset algorithm to obtain a first imaging result, the first imaging result corresponding to a slowness-frequency domain representation.

Abstract: A semi-automated method of replacing micropipettes using a micromanipulator is disclosed. A first micropipette is moved at a known angle from a work position to a distal position under automatic control of the micromanipulator. A replacement micropipette is then mounted in the micromanipulator and is moved under automatic control to a position proximate to the work position. The distance between the work position and the proximate position is substantially equal to the range of manufacturing variability of the micropipettes. The second micropipette is then moved by manual control of the micromanipulator from the proximate position to the work position by moving it in a linear path along the known angle so that the final approach to the work position can be visually monitored.
