Abstract: The present disclosure provides a method and a system for quickly determining transient stability of a half-wavelength transmission system. The method includes: obtaining power and a power angle of a feeding-end generator of a half-wavelength transmission system; and determining transient power angle stability and a power angle instability mode of the half-wavelength transmission system by using a constructed index system, where two power angle instability modes, that is, an instability mode 1 and an instability mode 2, are specifically constructed for the half-wavelength transmission system based on an equal area method. Based on the equal area method, the present disclosure constructs two instability modes specific to the half-wavelength transmission system, so as to accurately describe transient power angle characteristics of the half-wavelength transmission system under a severe fault, and characteristics of the two instability modes are significantly different from those of an AC transmission mode.

Abstract: Provided are a payment method, an electronic device and a non-transitory computer-readable storage medium, the payment method is applied to the electronic device. The electronic device includes a first processor and a second processor. The first processor is configured to run a first system, and the second processor is configured to run a second system, where power consumption of the second processor is lower than power consumption of the first processor. The electronic device is in a second system state in which running of the electronic device is controlled under the second system. The method includes: sending, by the second system, a payment instruction to a first system; receiving a payment graphic code that is generated and returned by the first system according to the payment instruction; and making, by the second system, a payment through the received payment graphic code.

Abstract: An inter-processor communication method, an electronic assembly, and an electronic device are provided. The electronic device at least includes a first core and a second core. A plurality of communication channels is defined between the first core and the second core. Each of the plurality of communication channels having a communication performance different from each other. The inter-processor communication method includes: acquiring to-be-transmitted data, the to-be-transmitted data is data transmitted between the first core and the second core; acquiring a corresponding communication channel corresponding to the to-be-transmitted data from the plurality of communication channels as a target communication channel; transmitting the to-be-transmitted data via the target communication channel.

Abstract: A processor communication method is implemented by an electronic device including a first processor and a second processor. The method includes the operations as follows. The first processor transmits a first master interrupt signal to the second processor, in response to detecting a downlink packet. The first processor receives a first slave acknowledge signal returned from the second processor based on the first master interrupt signal. The first processor transmits the downlink packet to the second processor based on the first slave acknowledge signal, and transmits a second master interrupt signal after completion of the transmitting of the downlink packet. The second master interrupt signal is used to instruct the second processor to transmit a second slave acknowledge signal after completion of processing the downlink packet.

Abstract: A support suitable for catalyst having a surface area in the range of from 80 to 200 m.sup.2 /g, a pore volume of from 0.3 to 0.5 ml/g, a side compression strength of from 70 to 240 N/cm and a pore diameter of from 60 to 200 Angstom units.
