transition metal

音標(biāo)發(fā)音

The HF-solvated Ag2+ ion (silver has the highest second ionization potential of any transition metal) oxidizes Xe at ordinary temperatures (Zemva et al., 1990) to make XeF2.
在過渡金屬中，銀的二階電離勢最高。在常溫下，HF溶劑化的Ag2+離子可氧化Xe生成XeF2。
‘For example, we can put something such as sodium in the core, mixing with a transition metal and then coated with a protective outer layer. I don’t think you could make these by any other means.
例如，我們可以將鈉與一種過渡金屬作為內(nèi)核，并在外面包裹一層保護(hù)層。
The chemisorption of aromatic molecules on transition metal is of great interest due to extensive use in petrol-chemistry industry and environment protection.
由于在石油化工和環(huán)境保護(hù)方面的廣泛應(yīng)用，芳香分子在過渡金屬表面的吸附成為人們研究的熱點。

And often, if you want to make a lot of it, you have to think about the thermodynamics of the system, how fast the reactions will go and kinetics, and then whether they'll go, the thermodynamics, and sometimes then you need to adjust the reactions, maybe use a transition metal to make it go better.
這種分子就不能正常工作，而且通常來說,如果你要大量生產(chǎn)一個東西,你必須考慮系統(tǒng)的熱力學(xué)，反應(yīng)速率和動力學(xué),還有反應(yīng)是否會發(fā)生，熱力學(xué)，而且有時候你需要調(diào)整反應(yīng)的發(fā)生。

any of a group of metal chemical elements including copper and gold that show more than one valency (= the number of hydrogen atoms that can combine with one of its atoms to form a compound)

any element belonging to one of three series of elements with atomic numbers between 21 and 30, 39 and 48, and 57 and 80. They have an incomplete penultimate electron shell and tend to exhibit more than one valency and to form complexes

It indicates that the formation of the coordination polymers takes on specificity. 2) The transition metal ions show important control ability on the structures of coordination polymers.
結(jié)果表明：1)改變反應(yīng)物的配比所得只有一種組成的產(chǎn)物，說明晶體的形成具有專一性；2)配合物隨配位中心構(gòu)型的不同表現(xiàn)為不同的維數(shù)，說明金屬離子配位方式的改變一定程度上可以導(dǎo)致配位聚合物維數(shù)的轉(zhuǎn)變。
