Abstract: Provided are a chip matrix, a sequencing chip, and a manufacturing method thereof. The chip matrix includes: a wafer layer (111), the wafer layer (111) having cutting lines that are evenly distributed thereon; a first silicon oxide layer (112), the first silicon oxide layer (112) being made of silicon oxide and formed on an upper surface of the wafer layer (111); a transition metal oxide layer (113), the transition metal oxide layer (113) being made of transition metal oxide and formed on an upper surface of the first silicon oxide layer (112). The chip matrix has characteristics such as resistances against high temperature, high humidity and other harsh environments. Meanwhile, by changing pH, surfactant and other components of a solution containing sequences to be sequenced, a surface functional region of the chip matrix can specifically adsorb a sequence to be sequenced.

Abstract: The present disclosure discloses a walking power control system for wolfberry picking, including a frame, a turntable, rotating rods, first gears, second gear, gear racks, supporting rods, hydraulic motors, a front traveling wheel, a left traveling wheel and a right traveling wheel. In the present disclosure, hydraulic motors rotate to drives three traveling wheels to rotate, thereby driving the frame to move, when it is necessary to turn, a turntable is rotated, the turntable rotates to drive two first gears to rotate, and the two first gears rotate to drive the supporting rods to rotate, thereby driving the left traveling wheel and the right traveling wheel to rotate, so that the traveling direction of the frame is changed. The picking speed of wolfberries is greatly improved, thereby improving the working efficiency and saving a lot of human resources.

Abstract: The embodiments of the present disclosure disclose a display method and an electronic device. The method comprises: projecting, by a first display unit, a first content; detecting, by a detection unit, an input operation relative to the first content, wherein a detection range of the detection unit corresponds to a projection range of the first display unit, and a bearing surface for displaying the first content is located within the projection range; judging whether the input operation satisfies a first condition to obtain a judgment result; and projecting a second content based on the judgment result, the second content comprising the first content and a prompt content for prompting that the first condition is satisfied.
