Abstract: A baby carrier includes a carrying assembly and a support sheet. The carrying assembly includes a waist member and two shoulder straps. A front end of the waist member is connected with a lower portion of the support sheet. An upper portion of a front end of each shoulder strap is connected with an upper portion of the support sheet. A rear end of each shoulder strap is connected with a middle portion of the support sheet. A lower portion of a front end of each shoulder strap forms a circular structure connected with the waist member. A fixing member is disposed on the front end of the waist member. The lower portion of the front end of each shoulder strap is slidably connected with the fixing member. A width between the two shoulder straps is adjusted by a slide of each shoulder strap on the fixing member.

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: 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: The present application relates to a characterization method for fine-grained sedimentary rock laminar texture, including S1: image preprocessing; S2: loading the image, and normalizing the image to a specified size; S3: performing mean filtering, dilation operation and binarization processing on the image; S4: determining whether laminars are developed; S5: determining the number of bright laminars and dark laminars; S6: determining the continuity of bright laminars and dark laminars; S7: according to the statistical result and the calculation result, recording the characterized parameters into Excel. The present application can accurately characterize the texture features of fine-grained sedimentary rock laminar. Compared with the prior art, the present application have higher efficiency and satisfies the requirement of symmetrically depicting the growth features of fine-grained sedimentary rock laminar, and a technical support is provided for the exploration and development of shale oil and gas.
