Abstract: The present disclosure discloses a method for preparing a bio-nylon fiber including plant active components. The method includes extracting a first component, extracting a second component, preparing a first active component, preparing a second active component, preparing a functional masterbatch, and spinning. Where extracting the first component includes performing an ultrasonic extraction for Speranskia tuberculata. Extracting the second component includes performing an ultrasonic extraction for a mixture of Artemisia argyi, Lygodium japonicum and Carthamus tinctorius. Preparing the first active component includes processing a mixture of nano-mesoporous silica and perlite with N-(?-aminoethyl)-?-aminopropyltrimethoxysilane and ?-aminopropyltrimethoxysilane, and processing the mixture with a sodium mercaptoacetate solution, and then loading the mixture with the first component solution to obtain the first active component.

Abstract: A two-dimensional compression method and system for compressing a bi-level bit-mapped image. The compression system reads a current row of data from the bit-mapped image and compares the current row with the row immediately preceding the current row, called the reference row. If a byte in the current row is equal to a corresponding byte in the reference row, then the byte is represented by a COPY mode and the byte is copied from the reference row to a compressed row. If the byte is not equal to the byte in the reference row, then the next byte in the current row is read and compared with the preceding byte. If the current byte equals the preceding byte, then the byte is represented by a REPEAT mode and copied to the compressed row along with a count of how many times to repeat the byte. If the current byte is not equal the preceding byte, then the byte is represented by a LITERAL mode and the byte is copied directly to the compressed row along with a count of how many bytes are to be copied.
