Abstract: The present disclosure provides an edge and bottom water invasion simulation apparatus and method, a storage medium, and a product. A controller controls an inert gas to be injected into a first intermediate container, and stops the injection. The controller controls formation water to be injected into the first intermediate container, and stops the injection. The controller controls the first intermediate container to be communicated with a core holder, and adjusts a pressure of a back pressure valve, so that the formation water enters a core to simulate edge and bottom water invasion. In the present disclosure, by adding the inert gas and the formation water to the intermediate container, an infinite edge and bottom water with sufficient energy at an early stage of a water invasion and a limited edge and bottom water with lower energy at a later stage of the water invasion can be effectively simulated.

Abstract: A method for preparing continuous bamboo fibers, which relates to a technical field of bamboo fiber preparation. The method includes processing bamboo raw materials into reticulated bamboo fiber strips, screening the bamboo fiber strips, dividing the reticulated bamboo fiber strips with different properties according to product requirements, performing high pressure splitting on the reticulated bamboo fiber strips which conforms to a screening condition, separating the bamboo fibers with different slenderness ratios from the bamboo fiber strips after the high pressure splitting is performed, forming a partial oriented bamboo fiber mat with uniform density by the bamboo fibers, forming an oriented bamboo fiber bundle with uniform linear density by the bamboo fiber mat, twisting the bamboo fiber bundle to form a bamboo fiber yarn, forming a rope by the bamboo fiber yarn, and forming a spindle based on a specifications.

Abstract: The disclosure relates to the technical field of air ducts, and in particular to a weather-resistant plant fiber-reinforced air duct with a multi-layer wall, and a preparation method thereof. The weather-resistant plant fiber-reinforced air duct with a multi-layer wall includes an outer isolation layer, a plant fiber-reinforced thermal insulation layer, a moisture-proof layer and a sealing layer that are arranged in sequence from inside to outside. The plant fiber-reinforced thermal insulation layer is prepared by the paving and laminating of surface fiber foam materials and core fiber foam materials or by the winding and molding of glass fibers and plant fibers. An outer isolation layer is adopted to protect the plant fiber-reinforced thermal insulation layer from being damaged by rubbing, and the moisture-proof layer and the sealing layer are adopted to ensure that the air does not leak out.

Abstract: A method for preparing continuous bamboo fibers, which relates to a technical field of bamboo fiber preparation. The method includes processing bamboo raw materials into reticulated bamboo fiber tapes, screening the bamboo fiber tapes, dividing the reticulated bamboo fiber tapes with different properties according to product requirements, performing high pressure splitting on the reticulated bamboo fiber tapes which conforms to a screening condition, separating the bamboo fibers with different slenderness ratios from the bamboo fiber tapes after the high pressure splitting is performed, forming a partial oriented bamboo fiber mat with uniform density by the bamboo fibers, forming an oriented bamboo fiber bundle with uniform linear density by the bamboo fiber mat, twisting the bamboo fiber bundle to form a bamboo fiber yarn, forming a rope by the bamboo fiber yarn, and forming a spindle based on a specifications.

Abstract: Minimal Motifs of linear B-cell epitopes in L1 structure protein from human papillomavirus type 58 (HPV 58) and their applications are disclosed. Eighteen linear epitope motifs and their extended 8-mer peptides in the L1 protein from HPV 58 are described, which can be used as antigens separately or in combination to specifically detect the serum from subjects with HPV 58 infection, or to develop preventive or therapeutic multi-epitope peptide vaccines against HPV 58 by inducing humoral immunity. Of the eighteen B-cell epitope motifs, ten of them are 100% conservative and one is highly conservative among many homologous proteins of high-risk HPVs. They can be used as candidate “universal” epitopes to develop preventive or therapeutic HPV vaccines. The amino acid sequences of the epitope motifs and the 8-mer peptide formula of the invention are shown below in SEQ ID No. 1-2, 2B, 3, 3B, 4-18, 18B, 19, 19B, and 20-32.
