| In the Introduction they state The high resolution and sensitive system have the ability to obtain the result of elemental composition analyses . This is true only if there are enough ions in the isotopic envelope that allow to extract valuable information about the isotopic composition of each individual ion (ion intensities must reflect the correct isotopic distribution for any given ion within the isotopic envelope). |

在引言中他們說高分辨率和靈敏度的系統(tǒng)具有獲得元素組成分析結(jié)果的能力。僅當(dāng)滿足如下所述時這才是對的,即“同位素封”中有足夠的離子以取得關(guān)于每個單個離子的同位素組成的有價值的信息(離子強度必須反映“同位素封”中任一給定離子的正確的同位素分布)。 “isotopic envelope”太專業(yè)了,暫時翻譯成“同位素封”吧,不知道對不。其它翻譯絕對沒問題。 |

| "isotopic envelope"沒必要理解啊,也沒必要強翻譯,好多專業(yè)詞匯不用強翻譯的。比如說"toluene",你若不知道它是“甲苯”的意思有時也沒關(guān)系啊,只要知道它是一種化學(xué)藥品就行了。這里你只需知道“isotopic envelope”是存放好多離子的地方就行了,我覺得跟“離子阱”差不多,看樣子小點,^_^。若想徹底弄懂就得深入學(xué)習(xí)這方面的專業(yè)知識(尤其是外文文獻和專著)了,那就看你投入值不值得了。不可能通過一篇文章就懂的。 |

The collection of peaks (signals in a mass spectrum) for a peptide containing different numbers of heavy atoms is referred to as an isotope envelope. For a small peptide, the first (lightest) peak in the envelope is the most intense peak. This is not the case for larger molecules in which the incorporation of naturally occurring heavy isotopes becomes statistically more and more likely and hence the isotope envelope shifts to higher and higher masses. |
