1)  isotopic system
同位素体系
1.
Fast neutron activation method based on the ~(40)Ar/~(39)Ar isotopic system and its application in geosciences;
~(40)Ar/~(39)Ar同位素体系及其在地学上的应用
2)  Sm-Nd isotope systematics
Sm-Nd同位素体系
1.
Both Sm and Nd are similar in ionic radius and in chemical properties, the daughter 143 Nd decayed by the parent 147 Sm through α-process can occupy the same site in mineral lattice as its parent, thus Sm-Nd isotope systematics is easily be closed and can resist later alteration and weathering.
Sm、Nd的离子半径相似、化学性质很相近,母体衰变形成的子体易在矿物晶格中保存下来,故矿物或岩石中的Sm-Nd同位素体系易保持封闭,具有较强的抗风化、抗蚀变能力,是一种有效的定年工具。
3)  potassium-calcium isotopic system
钾钙同位素体系
4)  Rb Sr isotopic system
Rb-Sr同位素体系
5)  Re-Os isotopic system
Re-Os同位素体系
1.
The method and principle of Re-Os isotopic geochemistry system are briefly sketched, on the basis as above, some new results at home and abroad to research source of ore-forming materials and mineralization chronology by Re-Os isotopic system are introduced.
简述了Re-Os同位素地球化学体系的原理与方法,在此基础上重点介绍了国内外目前在矿床地球化学研究中,应用Re-Os同位素体系进行成矿作用年代学及矿质来源等方面研究的一些最新成果。
6)  U-Pb isotopic system
U-Pb同位素体系
补充资料:氢同位素动力学同位素效应
分子式:
CAS号:

性质:在化学反应过程中反应物本身因同位素取代而改变能态,引起化学反应速度的差异。氢同位素动力学同位素效应很大,α=kH/kD可达2~10左右。0℃时Al4C3与水反应α=3.9,30℃时Fe与H2SO4反应α=6.6。轻水电解时比重水分解速度快,动力学同位素效应随电极材料、电解条件而变,氢-氘的α在3~12之间。当前采用减容电解来制取终浓重水。
