Abstract: A preparation method for raw bamboo fiber strips and a processing machine are provided. The preparation method includes: cutting bamboo wood into bamboo tubes according to a length of each of bamboo joints, and cutting the bamboo tubes into bamboo pieces; processing the bamboo pieces into the bamboo fiber skins through a processing machine; performing fermentation treatment on the bamboo fiber skins, and performing drying treatment after the fermentation is completed; performing kneading, oiling and conditioning treatments on the dried bamboo fiber skins; performing combing and drawing treatments on the conditioned bamboo fiber skins; and zoning and storing.

Abstract: Original ecological bamboo fibers and a preparation method and application thereof are provided in the present disclosure, belonging to the technical field of bamboo fibers, where the preparation method includes the following steps: cutting a bamboo material into sheets, feeding, slicing to obtain thin-layer bamboo slices, followed by cake pressing and cooking treatment, then cleaning and post-processing the bamboo slices to obtain the original ecological bamboo fibers. The present disclosure also discloses the original ecological bamboo fibers prepared by the preparation method and the application thereof in preparing bamboo fiber yarns.

Abstract: A boundary protection method and system of a radiation detection robot. The boundary protection method comprises: a first laser radar and a second laser radar are arranged diagonally, a first marking rod and a second marking rod are arranged diagonally; a boundary of an interlocking zone is defined by the first laser radar, the second laser radar, the first marking rod and the second marking rod; the object to be detected is placed in the interlocking zone; the radiation detection robot uses rays to detect the object to be detected in the interlocking zone; an early warning zone is provided outside the interlocking zone; wherein when it is detected that a person or object has intruded into the interlocking zone, the radiation detection robot stops emitting rays; and when it is detected that a person or object has intruded into the early warning zone, a warning is issued directly.

Abstract: This invention discloses an expression vector system comprising a promoter recognized and regulated by a heat shock sigma factor of E. coli, especially ?32. Preferably, the promoter comprises the consensus sequence of E. coli heat shock promoters as shown in SEQ ID NO:1. Also disclosed are methods for producing proteins using the promoter under heat shock conditions. Furthermore, the present invention discloses a method for creating a sudden temperature shift in a cell culture which has been pre-cultured to reach an optimal condition and which temperature shift will allow optimal production of a recombinant protein under the control a heat shock promoter.
