例句與造句

1. First , a terminal double bond was introduced into 3 - amino - 9 - ethylcarbazole ( aec ) via methacryloyl chloride to obtain the compound , 3 - ( n - methacryloyl ) amino - 9 - ethylcarbazole ( mec ) . second , mec was copolymerized with butyl methacrylate to prepare the mec - immobilized polymer particles . the resultant polymer particles were used as a fluorescence probe , which was almost free of dye leaching , and had higher photostability in comparison with free aec
   首先利用甲基丙烯酰氯向3 -氨基- 9 -乙基咔唑( aec )分子中引入末端雙鍵,得到帶末端雙鍵的熒光指示劑3 - ( n -甲基丙烯?；?氨基- 9 -乙基咔唑( mec ) ,然后通過(guò)乳液聚合技術(shù)將mec共價(jià)固定到聚甲基丙烯酸丁酯基體上,制得一種共價(jià)固定了mec的聚合物顆粒。
2. In this thesis , several new fluorescence carriers have been synthesized bearing a carbon chain with a terminal double bond introduced into the molecule and copolymerized with a monomer under uv irradiation on the silanized glass or quartz disk . the sensors prepared were studied . covalent immobilization effectively prevents the leakage of the carrier dye from the sensor membrane , a phenomenon that shortens the lifetime of ordinary optical sensors
   本論文合成了幾種含末端雙鍵、可共價(jià)固定的新型熒光化合物，并以此作為熒光指示劑，與膜基質(zhì)單體在光引發(fā)劑作用下發(fā)生光聚反應(yīng)共聚在經(jīng)過(guò)硅烷化處理的石英或普通玻片上制成光極膜，制備了對(duì)一些物質(zhì)有響應(yīng)的熒光化學(xué)傳感器。
3. It's difficult to find terminal double bond in a sentence. 用terminal double bond造句挺難的
