Is there any organic trouble which is fatal ? 有沒有什么官能上致命的毛病呢?
Vision and hearing are exteroceptive senses . 視覺與聽覺都是感受外界刺激的官能。
"peace, woman," said the gentleman, "your boy was in possession of all his senses. " “住口,婆子,”紳士說道;“你的兒子各種官能全有。”
Wholly untaught, with faculties quite torpid, they seemed to me hopelessly dull . 她們完全沒有受過教育,官能十分遲鈍,在我看來笨得毫無希望。
By definition an exclusively difunctional monomer can only give rise to a linear polymer . 按照定義,一個特定的雙官能單體,僅僅能得到線型聚合物。
We have, therefore, in both of the examples above, heterocyclic compounds with "built-in" or latent functionality . 上述兩例中的雜環(huán)化合物,都具有“固有的”或潛在的官能基。
He took his tea quietly; though his tongue was still, his observant faculties seemed by no means off duty . 他在不聲不響地喝茶;他雖然嘴巴不動,他的觀察官能卻似乎一刻也沒有離開職守。
Treatments of pyrylium salts with various nucleophilic reagents allows the production of a host of functionalized derivatives . 如果各種親核試劑與吡喃鹽反應(yīng),就可制取許多種帶官能基的衍生物。
Difunctionality, which is the essential characteristic of a polymer precursor, may be achieved in many different ways . 能生成聚合物的物質(zhì)其不可缺少的特點是具有雙官能性。這種雙官能性可用多種方法獲得。
Clearly the principle requirement for a substance to be capable of forming a structural unit of a polymer chain is that it must be difunctional . 顯然,對于能成為聚合物鏈結(jié)構(gòu)單元的物質(zhì)的基本要求是:它必須是雙官能的。
