Abstract: The present invention relates to a method for preparing high performance polymer-based conductive composites by space-limited micro-nano precision assembly method, which belongs to the technical field of composite material preparation; including the following steps: (1) through blending the conductive filler and the polymer matrix which are added to the blending equipment, homogeneous polymer/conductive filler material system is obtained; (2) add the homogeneous material system to the mold composed of two flat plates, and let the homogeneous blend gets plane limited compression by means of mechanical compression; (3) making use of the micro-nano structure array set on the compression template to further compact the filler on the network and conducting “array anchorage”, to realize the micro-nano precision assembly of network and obtain the composite material with excellent performance, which has a continuous and tight conductive network, and has excellent tensile properties, flexibility and thermal stability.

Abstract: A control method and a control device applied in a computer system, and a computer system are described. The control method according to the embodiments of the present invention is applied in a computer system, wherein the computer system includes a system memory containing two divided storage areas with the two storage areas being respectively a first storage area and a second storage area. The control method includes loading a first operating system into the first storage area; running the first operating system; and starting up a system memory access drive by the first operating system, so as to load into the second storage area the pre-stored memory mapping data of the second operating system by the system memory access drive.

Abstract: The present invention provides a technical solution to reduce electromagnetic interference generated by a high-frequency switching electronic circuit. By adding a disturbance signal whose amplitude varies with time to the input pin of the active power factor correction module of the high frequency switching electronic circuit which is intended to receive an input power control signal, the switching frequency of the active power factor correction module varies with time, so that the electromagnetic interference energy is dispersed in a frequency domain and the electromagnetic interference is reduced. While the effect is even more apparent particularly when the power supply of the high-frequency switching electronic circuit is a DC power source.
