Abstract: Disclosed are an information interaction method and apparatus, and an electronic device. One specific embodiment of the method comprises: in response to a user logging in to a live interface initiated based on a multimedia conference, displaying a live data stream of the multimedia conference in the live interface initiated based on the multimedia conference, wherein the live data stream is generated on the basis of an interactive data stream of a participating user of the multimedia conference; receiving interactive content input by the user on the basis of the live data stream, and generating interactive information according to the interactive content; and sending the interactive information to a serving end, so as to instruct the serving end to send the interactive information to a terminal device that displays the live interface. The communication efficiency of information related to the content of a multimedia conference is thus improved.

Abstract: The present invention belongs to the technical field of metabolomics, and relates to a metabolomics relative quantitative analysis method based on UPLC/HRMS. Specifically, the present method mainly comprises the steps of formulating an isotope internal standard mixed solution, a standard curve correction solution, and a metabolomics sample solution; acquiring raw mass spectrum data of the standard curve correction solution and the metabolomics sample solution; transposing and deconvolving the raw data; identifying and selecting the optimal isotope internal standard; fitting a linear equation and calculating the relative quantitative results of metabolites in the metabolomics sample solution; and completing the structural identification of metabolites and differential metabolites in the metabolomics sample solution.

Abstract: Disclosed in the embodiments of the present disclosure are an interaction method and apparatus, and an electronic device. A specific implementation of the method comprises: receiving a multimedia data stream sent by a user participating in a multimedia conference; determining a live multimedia data stream from the multimedia data stream based on a received live instruction of the multimedia conference; and transmitting the live multimedia data stream to a live server, in order that the live server generates a live data stream from the multimedia conference based on the live multimedia data stream.
