A method for synthesizing influenza virus-like particles within a plant or a portion of a plant is provided. After allocating part of the cell downlink power to the set of channels, the node allocates only a portion of the remainder of the cell downlink power to the high-speed shared channel. The selection and enrichment method utilizes a polynucleotide adaptor which when ligated to the polynucleotide fragment enables amplification to occur in the presence of an adaptor specific primer. Whereby, the device can modify the light-projected image and sensor view region with its control unit. When the fluorine-containing copolymer is used as an active ingredient of a surface modifier, the heat resistance of the surface modifier can be further improved.
