| 化學(xué)專業(yè)的同學(xué)請幫忙寫成地道的英文，謝謝我寫的句子太中式了， 請幫忙寫成地道的英文，非常感謝。①這些物質(zhì)中，物質(zhì)A、B和C為同系物。他們的結(jié)構(gòu)中都含有物質(zhì)A的結(jié)構(gòu)。B比A多一個(gè)甲基，C 比A多兩個(gè)甲基。Among these compounds, A, B and C were homologues. They all contain A structure framework. There one more methyl in the structure of B than A, and two more methyl groups in the structure of C than A. ②隨著碰撞能量的增加，m/z 100的峰增加一點(diǎn)，但并沒有新的峰再出現(xiàn)。當(dāng)碰撞能量達(dá)到40eV時(shí)，m/z 100的峰消失了。As the increasing of collision energy, the peak abundance at m/z 100 increased a little, and there was no more obvious new product ion anymore. When the collision energy was up to 40 eV, the peak at m/z 100 disappeared. |

這個(gè)永不者化學(xué)專業(yè)的就可以搞定： ①這些物質(zhì)中，物質(zhì)A、B和C為同系物。他們的結(jié)構(gòu)中都含有物質(zhì)A的結(jié)構(gòu)。B比A多一個(gè)甲基，C 比A多兩個(gè)甲基。 Among these compounds, A, B and C are homologues，all of which have A structure framework. Comparing with A, B has one more methyl while B has two more methyl groups in their structures, respectively. Side note: 描述結(jié)構(gòu)為什么用過去式呢？難道昨天是同系物，明天就不是了？ ②隨著碰撞能量的增加，m/z 100的峰增加一點(diǎn)，但并沒有新的峰再出現(xiàn)。當(dāng)碰撞能量達(dá)到40eV時(shí)，m/z 100的峰消失了。 With the increasing of collision energy, the peak abundance at m/z 100 increased slightly, with no extra peaks （or product ions）. However，the peak at m/z 100 disappeared when the collision energy was increased to up to 40 eV. |
