The invention discloses an AHB / APB expansion bus interface and a system-on-chip, and the expansion bus interface comprises a plurality of bus connectors which are used for being connected with corresponding external equipment, and comprise external equipment controllers and at least one group of registers; an address decoder used for connecting the AHB / APB bus of the micro-control unit with the plurality of bus connectors, mapping peripheral address signals sent by the micro-control unit through the AHB / APB bus into register address signals of the corresponding bus connectors, and further sending the register address signals to the corresponding bus connectors; and a multiplexer used for connecting the AHB / APB bus with the plurality of bus connectors and establishing connection between theAHB / APB bus and the bus connector selected by the chip selection signal according to the chip selection signal sent by the micro-control unit through the AHB / APB bus so as to transmit a data signal.By means of the mode, the MCU kernel can extend more external devices, and the usability and the expandability of the MCU are improved.

The invention discloses an integrated bionic liquid-absorbing core for a loop heat pipe, a preparation method and an application. The integrated bionic liquid-absorbing core includes a base body, a liquid compensation chamber and a capillary suction channel; the liquid compensation chamber is provided with a liquid inlet, and communicates with the capillary suction channel at the downstream port of the liquid compensation chamber, and the downstream of the capillary suction channel The port is a steam outlet; the liquid compensation chamber and the capillary suction channel are arranged in multiple levels to form a tree-like multi-level bionic channel, and the diameter satisfies Murray's law. The preparation of the integrated bionic liquid-absorbing core combines selective laser sintering 3D printing technology, and the preparation process is simple and convenient. The invention integrates the liquid-absorbing core and the liquid compensation chamber, and connects them through a multi-stage bionic channel based on Murray's law. When applied to a loop heat pipe, it can ensure that the liquid-absorbing core has a large capillary suction force and reduce the liquid labor cost. It has low mass flow resistance and excellent anti-gravity running performance, so it has a good application prospect.

The invention discloses a control circuit, a control method and a corresponding pulse source system of a pulse output source. The control circuit includes a trigger part, a cascade charging and discharging part and a load part, and the cascading charging and discharging part includes a plurality of sequentially cascaded units, each of which includes an avalanche transistor, an avalanche transistor for switch control Transistor (hereinafter referred to as: controllable transistor), current limiting resistor and charging capacitor; wherein the base of the controllable transistor in each of the above units is used to receive a control signal, so that the charging capacitor in the unit can be selected to be excluded Outside the discharge capacitor group, in order to realize the adjustment of the output power of the pulse output source. The invention selectively collects electricity from the energy source, is low in cost, and is easy to manufacture. The pulse source system can meet the requirements of more application scenarios while increasing control flexibility.
