化學(xué)工程與工藝專(zhuān)業(yè)英語(yǔ) 1 成績(jī)計(jì)算辦法: 平 時(shí) 點(diǎn) 名: 20% 平 時(shí) 作 業(yè): 30% 期 末 考 試: 50% (開(kāi)卷考試 !) 主要內(nèi)容 ? 無(wú)機(jī)化合物的命名 ? 有機(jī)化合物的命名 ? 專(zhuān)業(yè)外語(yǔ)書(shū)上的部分單元 1,3,4 5,6,7 10,11,12,13 20,21 Nomenclature of inanic pound With the discovery of thousands of new inanic pounds it has bee necessary to revise the traditional rules of nomenclature. An international mittee has remended a set of rules for naming pounds, and these are now being adopted throughout the world. 隨著成千上萬(wàn)個(gè)新無(wú)機(jī)化合物的發(fā)現(xiàn) , 對(duì)傳統(tǒng)的命名規(guī)則進(jìn)行修訂就顯得很有必要 。 國(guó)際委員會(huì)提出了一套命名無(wú)機(jī)化合物的規(guī)則 , 這套規(guī)則已經(jīng)被全世界范圍接受 。 One of the principle changes is that proposed by Albert Stock and now known as the Stock system for naming the pounds of metal (oxides, hydroxides, and salts) in which the metal may exhibit more than one oxidation state. 其中一個(gè)主要的變化是 Albert Stock 提出來(lái)的Stock命名系統(tǒng) ,這個(gè)系統(tǒng)主要用于命名具有不同氧化態(tài)的金屬氧化物 ,金屬氫氧化物和金屬鹽 。 Another important change is in the naming of plex ions and coordination pounds. ? In these case the oxidation state of metal is shown by the roman numeral in parentheses immediately following the English name of metal which corresponds to its oxidation number. 在這種情況下 , 金屬氧化態(tài)是以緊接著金屬的英文名稱(chēng)之后在圓括號(hào)中用羅馬數(shù)字表示 , 該數(shù)字與金屬的氧化數(shù)一致 。 ? Naming ions ? Naming metal oxides, bases, and salts ? Naming nonmetal oxides ? Naming acids ? Naming acid and basic salts ? Naming mixed salts 元素和單質(zhì)的命名 “ 元素 ” : element “單質(zhì) ” : element 有時(shí)為了區(qū)別 , 又叫 : free element 化合物: pound cover 9 Sblock Element IA H Hydrogen Li Lithium Na Sodium K Potassium Rb Rubidium Cs Cesium Fr Francium IIA Be Beryllium Mg Magnesium Ca Calcium Sr Strontium Ba Barium Ra Radium 10 Pblock Element VIA VIIA 0 He Helium O Oxygen F Fluorine Ne Neon S Sulfur Cl Chlorine Ar Argon Se Selenium Br Bromine Kr Krypton Te Tellurium I Iodine Xe Xenon Po Polonium At Astatine Rn Radon IIIA
