The invention relates to a method for preparing a porous graphene-like material from water hyacinth. The method comprises the following steps: washing water hyacinth, drying, carrying out acid boiling on dried water hyacinth in diluted HCl, carrying out pumping filtration, and carrying out vacuum drying; heating in N2 atmosphere to 300-900DEG C, and pre-carbonizing; mixing a pre-carbonized carbonization product with KOH, heating in N2 atmosphere to 400-1000DEG C, annealing for 1-10h, and cooling to room temperature; and cleaning the obtained sample by the diluted HCl, cleaning with distilled water until the sample is neutral, and drying at 80DEG C to prepare the porous graphene material. Living creature harmful to nature is used as a raw material, is changed to valuables, and is in favor of protecting environment; simple acid boiling and annealing treatment are adopted, and the thickness and the size of acid-boiled graphene flakes are controlled by controlling the acid boiling time and ...

The invention discloses a digital watermarking method based on a vector space data object storage sequence. Watermarking information is converted into an integer N through the arithmetic coding technology, the number M of least needed elements is worked out, the elements are all arranged, and the particular arrangement sequence of the elements with the serial number N is worked out. Vector data objects are ranked according to the coordinates and are grouped according to M pairs of data objects. The storage sequence of each group of data objects is adjusted according to the particular arrangement sequence of the elements with the serial number N. When the watermarking information is extracted, the data objects are ranked according to the coordinates and are compared with an original data object storage sequence, a watermarking unit and the particular data object arrangement sequence are extracted, the arrangement serial number N is worked out, the N is decoded through the arithmetic coding ...
