Abstract: A control method for an electric heating appliance having a first switch module, a second switch module, and a load, a control terminal of the first switch module being accessing a target pulse width modulation (PWM) signal, an output terminal of the first switch module being connected to a control terminal of the second switch module, an input terminal of the second switch module accessing a power supply voltage, an output terminal of the second switch module being connected to the load, and an output signal of the first switch module controlling the second switch module to be in an on state or an off state, includes: determining a first PWM signal, the first PWM signal being a signal loaded onto the control terminal of the first switch module in a state in which the first switch module operates independently, so as to drive the first switch module.

Abstract: An electronic atomization device includes: a heating element for atomizing an aerosol-forming material: an electromagnetic heating circuit with an inverse class-E characteristic; a power supply circuit connected to the electromagnetic heating circuit so as to supply power to the electromagnetic heating circuit; and a drive circuit connected to the electromagnetic heating circuit so as to generate a drive signal. The electromagnetic heating circuit controls, based on a change of the drive signal, the heating element to atomize the aerosol-forming material.

Abstract: A method for controlling an electromagnetic heating device includes: obtaining a sampling current obtained by a current sampling apparatus detecting a main loop in which an electromagnetic oscillation and power output circuit of an electromagnetic heating device is located; detecting, according to the sampling current and preset determining data, whether the electromagnetic heating device accommodates a medium; and controlling, if the electromagnetic heating device does not accommodate a medium, the electromagnetic oscillation and power output circuit to stop electromagnetic oscillation.

Abstract: The present invention provides a fungicidal composition and a fungicide for controlling asparagus stem blight, and belongs to the technical field of controlling asparagus stem blight. The composition includes difenoconazole and propamidine; and the weight ratio of the difenoconazole to the propamidine is 20:1-1:20. The fungicide of the present invention includes difenoconazole, propamidine and an auxiliary material; and the difenoconazole and propamidine account for 3%-90% by mass of the total amount of the fungicide. The present invention uses difenoconazole and propamidine as active ingredients, where a combined use of them has a synergistic effect on the pathogenic fungi of asparagus stem blight, and especially has an obvious synergistic effect on the asparagus stem blight in a ratio range of 20:1-1:20.

Abstract: A switch includes at least a first table and a second table different in mapping of egress information of a network and user information to a packet. The first table is searched for a first packet received and operation according to an action corresponding to a search key of the first table is applied to the first packet to convert the first packet to a second packet. The second packet is supplied to the second table. The second table is then searched for the second packet. When the search key of the second table is matched, the operation according to the action corresponding to the search key of the second table is applied to the second packet to convert the second packet to a third packet (refer to FIG. 5).

Abstract: A communication node is provided with: a group information storage unit that stores correspondence relationships between first communication group information that identifies communication groups in a first network, and second communication group information that identifies communication groups in a second network that can accommodate a larger number of communication groups than the first network; and a packet processing unit that refers to the group information to convert between first communication group information and second communication group information included in received packet(s). Communication is thus realized between terminals in which the first communication group information is different.
