常見(jiàn)例句雙語(yǔ)例句However, a virus called vaccinia spreads four times faster than what was thought possible.然而,一種名爲(wèi)牛痘的病毒傳播的速度比我們所能想像的快四倍。Just after vaccinia infects a cell, it expresses two viral proteins on the cell surface, which marks the cell as infected.牛痘剛感染一個(gè)細(xì)胞後,就在細(xì)胞表麪顯示出兩個(gè)病毒蛋白,這表明細(xì)胞已經(jīng)感染。Under normal conditions, vaccinia spread across one cell every 1.2 hours, which was slowed to one cell every five to six hours.正常條件下,牛痘病毒每1.2小時(shí)傳遍一個(gè)細(xì)胞,而現(xiàn)在減慢至每五六小時(shí)傳遍一個(gè)細(xì)胞。原聲例句We know now that it's caused by a related virus, called vaccinia, remember the virus that causes smallpox is called variola.我們現(xiàn)在知道這病由一種相關(guān)的病毒引起,這種病毒叫牛痘病毒,想想天花病毒也被叫做牛痘病毒耶魯公開(kāi)課 - 生物毉學(xué)工程探索課程節(jié)選So, how could you produce--the question is, how could you produce large quantities of this- of this microorganism, this virus vaccinia under controlled conditions?問(wèn)題是該怎麼進(jìn)行生産,你怎麼大批量生産這種微生物,即在可控條件下生産牛痘病毒耶魯公開(kāi)課 - 生物毉學(xué)工程探索課程節(jié)選Well, it turns out that we could not identify, at least at that point, a cell culture that would serve as a host for vaccinia.然而我們還不能斷定,至少這個(gè)時(shí)候無(wú)法斷定,這些被感染的細(xì)胞就是牛痘病毒的宿主耶魯公開(kāi)課 - 生物毉學(xué)工程探索課程節(jié)選權(quán)威例句In this case, a little genetic engineering convinced vaccinia to produce an important rabies antigen.FORBES: A Pox On Your House?
