Abstract: The present disclosure provides a method for recovering a porosity evolution process of sequence stratigraphy of carbonate rocks. The method comprises: a step of establishing a sequence stratigraphic framework of carbonate rocks; a step of dividing diagenetic stages; a step of simulating diagenesis and porosity evolution with increasing reservoir thickness and continuous superposition of multiple reservoirs during cyclic rise and fall of sea level to obtain a simulation result; and a step of calculating the porosity evolution in space over time by using the simulation result as initial values for simulation of diagenetic evolution process and simulating in stages and continuity the multi-stage diagenetic evolution process that the carbonate rock strata undergo after sediment based on the divided diagenetic stages.

Abstract: A high priority service sending method and device in a direct mode, and a high priority service receiving method and device in a direct mode. The receiving method includes: after sending a voice frame in a voice call sending state, a user terminal receiving and detecting a priority frame in another time slot with respect to the time slot occupied by the voice call; and if the priority frame is detected, then stopping the voice call and receiving a high priority service frame in the other time slot. Using the present invention can enable an interphone in a transmitting state in a direct mode to send or receive a high priority service as well.

Abstract: A realization method, apparatus and system for remote monitoring, the remote monitoring technique is used between interphones, which includes the following contents: a monitored party receives a remote monitoring request from a monitoring party, the remote monitoring request includes a target control information; the monitored party answers confirming information to the monitoring party after receiving the remote monitoring request successfully, and analyzes the target control information, and then selects transmission mode; the monitored party enters monitored state, starts transmission automatically, and implements the transmission according to the selected transmission mode. Applying the embodiments of the present invention, the remote monitoring function of a interphone will be improved, and the monitoring party can initiatively control the transmission time of the monitored party; or transmission interval and times of the monitored party, so as to realize the repeat monitoring is realized.
