Modern molecular biology experimental technique was used to construct the expression plasmid pGX6191 of ORF2 at first and biological proof was carried out, then the expression plasmid pGX6191 was mated into the polar mutant T2135 by tri-parent,and pathogenic relevant gene ORF3's mutant T2135/R was obtained.
With the widen of SHPB experimental technique application area and with the improve of the request for experimental equipment and experimental accuracy ,to improve and optimize SHPB experimental technique is very important.
The allotropic effect on the electronic stopping power of protons in solidswas systematically determined by the nuclear resonance reaction ~(27)Al(p,γ)~(27)Si at E_p=774 and 992 keV in an SOS sample of epitaxial Si on sapphire. Details of the experimental technique are described,the experimental error isless than 3%.
