When sequenced using the standard plasmid DNA cycle sequencing protocol,the inverted repeats form hairpin structure which reduces the sequence quality and length of Gateway clones.

Analyzed the technology characteristics of the barrette, introduced the injection mold structure and work principle.

Various sand-entraining fermentation tests suggested that sand-entraining (20 % of the amount of quality maternal fermented grains) could increase top-grade product r.

In order to improve interlayer pit mud fermentation,self-made pit mud fermenter was used and pit mud functional bacteria were supplied in each turn of fermentation.

By the analysis of stress, crack characteristics, cross section metallography, scanning electrometry microscopy, energy spectrum micro-area as well as material quality of top hair clip pipe of Primary reformer, finds out the reason for top hair clip pipe cracking is stress corrosion cracking, and puts forward defending measures.
