The present invention is a conjugated polymer that contains both Unit (I) and Unit (II) is shown below: X, in each occurrence, is independently selected from S or Se. M1 and M2 are independently selected from H or F. R1 and R2 are independently selected from straight-chain, branched or cyclic alkyl groups with 1-40 C atoms. The number ratio of Unit (I) and Unit (II) in the polymer chain ranges from 9: 1 to 1 :9.
An authorization method for a virtual key, a server, an authorization system and device, and a nonvolatile computer storage medium. The method comprises the following steps: receiving an authorization command sent by a first mobile terminal; integrating function authorization codes to form a code set, and sending the code set to a second mobile terminal of an authorized party by means of the first mobile terminal; receiving identity information and the code set sent by the second mobile terminal; and after verification succeeds, generating virtual keys, corresponding to the multiple function authorization codes, of multiple functions of a vehicle, and sending the virtual keys to the second mobile terminal. According to the authorization method, virtual keys, corresponding to multiple function authorization codes, of multiple functions of a vehicle can be generated, so that the controllability and flexibility of the virtual key authorization are improved, targeted key function authorization is achieved, and usage requirements of customers can be better met.
An encoding rate adjustment method, a base station and a terminal device. The base station receives encoding rate adjustment capability indication information about a terminal device, wherein the encoding rate adjustment capability indication information is used for indicating whether the terminal device supports cross-grade rate adjustment; if the terminal device supports cross-grade rate adjustment, the base station determines a cross-grade target encoding rate of the terminal device, wherein the cross-grade target encoding rate is not adjacent to or is adjacent to the current encoding rate of the terminal device; and the base station sends the cross-grade target encoding rate to the terminal device.

A power transmission system including the transmission unit and a vehicle including the power transmission system are also provided.
A prompt method for adding a quick link in a browser includes: obtaining a historical internet address database at the end of a period and counting the number of loadings of each historical internet address in the historical internet address database in the period; extracting the historical internet address with the number of loadings larger than a preset number threshold; and sending a push message based on the extracted historical internet address to send a prompt of adding the quick link to the user, wherein the push message is adapted to prompt the user to set the historical internet address as a quick link internet address; where the historical internet address database is adapted to record internet addresses of web pages, where the web pages are displayed on the foreground by a browser during the period and display durations of the web pages is longer than a preset duration threshold.
A water-soluble fluorescent liquid metal material uses a liquid metal as a substrate material, and is coated with a fluorescent dye, and the surface of the material is modified by a high molecular polymerization material to increase the hydrophily of the material. The mass percentage of the liquid metal in the material ranges from 0.1% to 5%, and the solubility of the water-soluble fluorescent liquid metal material in water is greater than or equal to 10 g/L. A preparation method for the water-soluble fluorescent liquid metal material. Compared with a macro-scale non-water-soluble liquid metal material, functions and properties of the water-soluble fluorescent liquid metal material are further extended, the biocompatibility of the liquid metal materials and the wettability of materials having different substrates are greatly reduced, and the original properties of the liquid metal material are also maintained.
