Abstract: A method of labeling video to provide authentication acquires an instruction to apply timestamp labeling. Each recorded video is labeled with a timestamp based on the instruction. The first mark information is generated based on a content of each recorded video as a hash value and is uploaded into a blockchain. Second mark information is generated based on a content of at least one video under investigation. By comparing the first mark information and the second mark information, a video under investigation is found to be undistorted and authentic when the first mark information is the same as the second mark information. The video under investigation is found to be non-authentic when the first mark information is different from the second mark information. A terminal device and a computer readable storage medium applying the method are also disclosed.

Abstract: The present disclosure relates to a catalyst composition for polymerizing propylene and a method for producing polypropylene. The catalyst composition for polymerizing the propylene includes a modifying agent. The modifying agent is an ester compound having hydrophilic groups and hydrophobic groups. In the method for producing the polypropylene, a reverse microcellular structure is formed by the modifying agent during a propylene polymerization, in which the hydrophilic groups are inside the reverse microcellular structure, and the hydrophobic groups are outside the reverse microcellular structure, such that polar substances in a raw material are retained inside the reverse microcellular structure. Thus, poisoning of the catalyst is reduced. Besides, the modifying agent can maintain a valence state of titanium in an active site of the catalyst at positive trivalent, such that the propylene polymerization between the titanium and the monomer is facilitated, thereby enhancing an activity of the catalyst.

Abstract: A gas permeable metal with a porosity gradient and a method of manufacturing the same are provided. A second lamination layer and a third lamination layer are respectively connected to two opposite sides of a first lamination layer. A pore diameter of the first lamination layer is larger than that of the second lamination layer. Thereby while being applied to molds, a mold cavity is mounted in the second lamination layer with smaller pore diameter so that products formed have fine and smooth surfaces. The arrangement of the first lamination layer with larger pore diameter is used for effective escape of gas generated during product production process. According to production requirements for products, a pore diameter of the third lamination layer can be adjusted to be not larger than that of the first lamination layer. Thus mechanical strength and gas exhaust capacity can be balanced.
