Abstract: A method for realizing stable display of a 5G signal includes when a master node is switched and a secondary cell group bearer is released in a dual-connectivity network, starting a first timer and displaying the 5G signal; when it is determined that the first timer expires and it is detected that a radio resource control is in an idle state, starting a second timer and displaying the 5G signal; when it is determined that the second timer expires and it is detected that the radio resource control is in a connected state, querying a number of data radio bearers and displaying a signal type according to the number of data radio bearers; and when it is detected that the radio resource control is in the idle state, querying an information database of a 5G cell and displaying the signal type according to information of the 5G cell.

Abstract: An icon display method for an electronic device is provided. The method includes: controlling the electronic terminal to display a 5G icon, after the electronic terminal establishes dual connections with an LTE network and an NR network; detecting whether the electronic terminal can currently access an NR secondary cell after a first preset time period is delayed, when an NR secondary cell accessed by the electronic terminal is released; and controlling the electronic terminal to continue to display the 5G icon if yes. A computer-readable storage medium and an electronic terminal are also provided.

Abstract: Disclosed are an icon display method and apparatus, a storage medium and an electronic device. The method is applied in an electronic device and comprises: detecting whether the electronic device can access a 5G network when the electronic device accesses a 4G network; if the electronic device can access a 5G network, sending an access request to a 5G network cell, and receiving an access result returned on the basis of the access request; and determining according to the access result whether an icon of the electronic device is displayed as 5G.

Abstract: Disclosed are a heavy oil activator, a preparation method and use thereof. The heavy oil activator has a structural formula shown in Formula (1). In Formula (1), x, y, z, m, and n are respectively mass fractions of corresponding chain segments in the polymer, m being 0.75-0.85, y being 0.20-0.24, and x, z, and n all being 0.001-0.01; and p is a natural number between 2 and 9. The activating polymer provided has the effects of increasing viscosity of an aqueous phase while reducing viscosity of crude oil, and can serve both as a displacing agent and a viscosity reducer to realize integration of the two agents.
