Burning fossil fuels by people adds about 5.5 GtC of carbon per year into the atmosphere.

燃烧化石燃料,每年就为大气层增加大约五十五忆吨碳.

Four gene polymorphisms were identified in exon 7. They were Gly 551 X ( GGC → GGT ), Arg 554 His ( CGT → CAT ), Gln 567 Arg ( CAA → CGA ) and Val 582 Ile ( GTC → ATC ).

同时在外显子7上发现4个位点的基因多态性,分别为Gly551X(GGC→GGT ) 、 Arg554His ( CGT→CAT ) 、 Gln567Arg ( CAA→CGA ) 和Val582Ile ( GTC→ATC ).

The most frequent rpoB gene mutations sites are Leu-531 ( 6 isolates , CAC → TAC ) , Tyr-526 ( l isolate , GAC → GTC ) and Val-516 ( 7 isolate, CAC → TAC ) .

19株 SSCP 阴性耐药株中经测序6株在531位密码子TCG→ TTG, 1株526位密码子CAC→ TAC,7株发生在516位密码子GAC→ GTC, 5株未改变.
