The present invention relates to a device and a method for inserting watermark information into a moving image. The copyright ownership of the moving image represented by the watermark information is inserted into some frames of the moving image at irregular intervals. These frames are of such a number that the watermark information in the moving picture is invisible to the naked eye. Also, in these frames, the insertion position of the watermark information is determined based on a random value, and besides that, information restricting the copying of moving images is inserted together with the watermark information. When the moving image has become a static image, the watermark information can be easily seen with the naked eye, so illegal ones such as illegal reproductions are easily exposed.

The cloth feeding mechanism of the embroidery machine guarantees the flatness of cloth between the front cloth clamping roller set and the rear cloth clamping roller set, and the embroidery quality is improved.

The invention belongs to the field of animal genetic engineering and relates to a zebrafish ZB transposon system and a transgenic method mediated by the ZB transposon system, which is derived from zebrafish and contains two terminal repeats that can be inserted into a target gene cassette The transgene donor plasmid of sequence and the transposase auxiliary plasmid providing transposition activity; the transgene donor plasmid includes the flanking terminal repeat sequence of the zebrafish ZB transposon and the Msc1 insertion cloning site. Also disclosed is a gene transfer method based on the ZB transposon system, which is to introduce the target gene into the recipient genome through the ZB transposon system. The present invention can be applied to multiple biotechnology fields: 1) The method provided in the present invention can be used to effectively insert the target gene cassette into the host genome to improve the efficiency of gene transfer; 2) Combined with gene capture technology, it can effectively carry out animal Gene function research; 3) It can mediate human gene therapy, etc.

The invention discloses a polyvinylamine composite functional membrane with lamella sieving channels and a preparation method and application of the polyvinylamine composite functional membrane. The preparation method comprises the following steps: dissolving an intercalation copolymer of graphene oxide and polyvinylamine into a polyvinylamine solution, dispersing so as to obtain a uniform film casting solution, and preparing the functional membrane on the surface of a micro-pore filtering membrane by using a coating method, wherein t he adjusting range of the interlayer distance of the intercalation copolymer is 8.-24.. Polyvinylamine is dropped into graphene oxide dropwise and is effectively inserted into graphene oxide lamellae, and thus the lamella copolymer of the graphene oxide and the polyvinylamine is prepared; and by adjusting the ratio of graphene oxide to polyvinylamine, the interlayer distance of the graphene oxide lamellae can be regulated and controlled. When applied to CO2 separation, the composite functional membrane has relatively high CO2 permeation rate and separation factor. The preparation method disclosed by the invention is simple in process and easy to operate, and the CO2 permeation property of a polyvinylamine membrane and the CO2 selectivity of CO2 / CH4 and CO2 / N2 are effectively improved.

The invention discloses pH sensitive-type Fe3O4 coated LDH methotrexate-loaded nano drug particles. According to the invention, LDH is directly added in a preparation system of Fe3O4 nanoparticles, while the Fe3O4 nanoparticles are formed, at the same time, the surface of the Fe3O4 nanoparticles is coated with LDH through a self-assembling mode, a Fe3O4 coated LDH carrier is formed, and MTX can effectively loaded on the Fe3O4 coated LDH carrier through a subject and object exchange technology.
