Abstract: A cryostat device for a superconducting magnetic levitation train includes a conduction assembly, a support assembly and a refrigeration assembly. The conduction assembly includes a conduction shell, a copper box arranged in the conduction shell, and a thermally-conductive support rod assembly. A top of the thermally-conductive support rod assembly is connected with a bottom of the copper box. A bottom of the thermally-conductive support rod assembly is connected with a bottom wall of the conduction shell. A top of the copper box is provided with a superconducting bulk accommodating cavity. The bottom of the copper box is provided with a cooling energy connecting end. A top of the support assembly is configured to support the conduction assembly. A bottom of the support assembly is connected with a bogie chassis. The refrigeration assembly is provided with a cooling energy input end connected with the cooling energy connecting end.

Abstract: A method for identifying and characterizing biological parts based on omics datasets and a dual-fluorescent reporter gene system, and a biological part library constructed thereon are provided, relating to a technical filed of biology. The method includes steps of: identifying the biological parts using the omics datasets; constructing a single-fluorescent reporter gene system using a shuttle vector pEZ15Asp as a skeleton for screening and determining fluorescent reporter genes; obtaining a dual-fluorescent reporter gene system skeleton; constructing recombinant plasmids, and finally transforming into competent cells for quantitative analysis of fluorescence intensities. The present invention is convenient and quick, and can screen and identify different biological parts such as RBS, UTRs, promoters, and terminators of different intensities in batch quantitatively in a relatively short time. Moreover, the present invention can quickly expand the biological part library of Z.
