The technology of this application relates to a memory management method and apparatus. When garbage collection is performed by using the method, stored information about a first reference cycle is first obtained, where the first reference cycle is a cyclic reference formed by a plurality of objects, and the information about the first reference cycle includes the plurality of objects in the first reference cycle and a reference relationship between the plurality of objects. The method further includes determining that a second reference cycle exists, where information about the second reference cycle matches the information about the first reference cycle, and the information about the second reference cycle includes a plurality of objects in the second reference cycle and a reference relationship between the plurality of objects. The method further includes reclaiming memory occupied by the plurality of objects in the second reference cycle.

The present disclosure discloses a wind-solar reactor system and a working method thereof. The wind-solar reactor system comprises a nuclear reactor system, a wind power generation system, a solar power storage system and a balance energy system, wherein the nuclear reactor system uses an integrated small modular reactor design, the solar power storage system uses a tower-type solar power storage system design, and a hydrogen production system uses a copper-chlorine cycle hydrogen production technology. A reactor keeps rated full-power operation, generated electricity is adjusted and distributed through a power controller, most of the electricity is used for smoothing the fluctuation of wind power generation, and the excess electricity is used for hydrogen storage of the hydrogen system. Solar power is used for heating saturated steam generated by the reactor into superheated steam through a heater, and then the superheated steam enters a high-pressure cylinder to do work by expansion.

Wind-solar reactor system and working method thereof

A heart rate detection method and an apparatus, where the method is applied to an electronic device, and the electronic device includes a heart rate sensor. The method includes detecting, by the electronic device, a current motion status of a user carrying the electronic device, determining, based on a prestored correspondence between a motion status, a startup period, and a sampling rate, a startup period and a sampling rate corresponding to the current motion status, where the startup period is a period in which the heart rate sensor is started to detect a heart rate of the user carrying the electronic device, and the sampling rate is a sampling rate of collecting heart rate data by the heart rate sensor, and starting the heart rate sensor at regular intervals based on the startup period to collect heart rate data at the sampling rate.

Heart rate detection method and apparatus

Embodiments of the present invention provide a channel switching method, apparatus, and device. The method includes: obtaining, by a mobile Wi-Fi device, a channel switching instruction sent by a Wi-Fi access point, where the channel switching instruction carries a destination channel identifier; and switching, by the mobile Wi-Fi device according to the channel switching instruction, a communication channel between the mobile Wi-Fi device and the Wi-Fi access point, and a communication channel between the mobile Wi-Fi device and a terminal that accesses the mobile Wi-Fi device to a destination communication channel corresponding to the destination channel identifier carried in the channel switching instruction. In this way, a Wi-Fi client and a Wi-Fi access end of a mobile Wi-Fi device still work on a same communication channel after performing channel switching, thereby improving compatibility, a throughput, and stability of the mobile Wi-Fi device.
