Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: The present disclosure provides a live-stream interaction method, a live-stream interaction system and related devices. The system includes a terminal of an audience, a terminal of an anchor, and a server; the terminal of the audience is configured to present a live-stream interface, and the live-stream interface includes an interaction control that supports interaction, and when the audience triggers an interactive behavior through the interaction control, an interaction image when the audience performs the interactive behavior is acquired; the terminal of the anchor is configured to send the behavior feature of the anchor to the server; the server is configured to acquire the behavior feature of the audience, match the behavior feature of the audience with the behavior feature of the anchor to obtain a matching result, and send a special effect instruction to the terminal of the audience according to the matching result.

Abstract: A preparation method of indium oxide with stable morphology includes: (1) mixing indium oxide powder and bismuth oxide powder according to a mass ratio of 1:0.1-0.5 to obtain a powder mixture; (2) putting the powder mixture into a ball mill for ball milling at room temperature to obtain a uniform powder mixture; (3) putting the obtained uniform powder mixture into a muffle furnace and calcining at 700-1000° C.; and (4) obtaining the indium oxide with cubic stable morphology after the muffle furnace naturally cools to room temperature. The method has advantages of simple synthesis process, short synthesis period, high sample yield, no need of complicated equipment, and morphology of the obtained indium oxide can be maintained after being heated at a high temperature within 1000° C. for 2 hours. An electrochemical sensor prepared by using the indium oxide obtained by the method has better selectivity to nonane.

Abstract: An optical module is disclosed. According to one implementation, the optical module comprises an optical receiver, a diode, a first resistor, a first capacitor, a comparator, and a control chip. The diode anode connects electrically with a triggering signal output end of the optical receiving module, the cathode of the diode connects with one end of the first capacitor and one input end of the comparator. Another end of the first capacitor connects with the ground; the first resistor is connected in parallel with both ends of the first capacitor. A pre-set reference voltage is connected with another input end of the comparator. The optical receiver generates a first triggering signal in response to a burst mode optical signal. After inputting the first triggering signal into the diode anode, the comparator outputs a second triggering signal from the output end, triggering the control chip to generate a reset signal input into the optical receiver.
