Abstract: A method and an Internet of Things system for smart gas adaptive pressure regulation based on a calorific value of gas are provided. The method comprises: acquiring calorific value of gas data, wherein the calorific value of gas data is acquired on the basis of a pressure regulation station; acquiring a first pressure regulation parameter of the pressure regulation station, wherein the first pressure regulation parameter is used for reflecting current pressure regulation data of the pressure regulation station; determining whether the calorific value of gas data meets a first preset condition; in response to the calorific value of gas data not meeting the first preset condition, adjusting the first pressure regulation parameter; and determining a second voltage regulation parameter of the pressure regulation station on the basis of the adjusted first voltage regulation parameter, wherein the second voltage regulation parameter is updated pressure regulation data.

Abstract: Disclosed is an antibody that specifically binds to BCMA. The antibody comprises a heavy chain variable domain VH, a light chain variable domain VL, and a chimeric antigen receptor that contains the sequence thereof. Further disclosed are the amino acid sequence, a vector, a host cell, and a composition of the antibody or the chimeric antigen receptor of the present invention. Also disclosed is a use of the antibody or the chimeric antigen receptor in the preparation of a drug for the prevention or treatment of diseases.

Abstract: A low-modulus high-adhesion silane-modified polyether sealant for prefabricated buildings is provided by including a composition A and a composition B, wherein the composition A includes silane-modified polyether, plasticizer, hydroxy-terminated branched polyether, branched polyether epoxy resin, coupling agent, thixotropic agent, silica, reinforcing filler A, hollow glass microspheres and toner, and the composition B includes plasticizer, hydroxy-terminated branched polyether, light stabilizer, reinforcing filler B, organotin catalyst and amine curing agent. The present disclosure also optimized the various ingredients in the silane-modified polyether sealant, and a formulation of sealant having the best bonding effect was obtained.

Abstract: An information transmission apparatus for logging while drilling comprises a hollow drilling rod and at least one cable. The drilling rod comprises at least one first drilling rod member and at least one second drilling rod member spliced to each other alternately. The first drilling rod member comprises a through hole, and the second drilling rod member comprises a stepped hole. The cable comprises a fixed end, a connected end, and a folded portion connect the fixed end to the connected end. Each of the cables is fixed in the stepped hole through a fixed end or is connected to a connected end of an adjacent cable. The connected end may be stretched along the stepped hole, and stretched through the through hole to be electrically connected to a logging instrument or a fixed end of the adjacent cable. The apparatus provides protection for a cable through a hollow drilling rod, thereby improving the transmission reliability.
