isotopes table───同位素表
The isotopes of a given element have the same chemical properties but slightly different physical properties.───一个特定元素的同位素具有相同的化学特征，但在物理性质上有一些细微差异。
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes.───大多数在水中氢和氧的原子是稳定的，但这两个元素的痕迹也存在重同位素。
Such anomalies are due to the relative abundance of the "isotopes" or varieties of each element.───这种反常现象是由于同位素比较丰富或者各个元素比较多样化。
The company has not yet been able to determine the source of those leaks, and confirming the isotopes' exact levels could take much longer.───核电站至今依旧没能找到泄露的源头，而确定同位素的确切含量也要花更多的时间。
I'm digging on the isotopes, this metaphysics shit is dope, and if all this can give me hope, you know I'm satisfied.───我在吸食同位素，这种形而上学的狗屎是毒品，如果这些能给我希望，你知道我很满意。
Yet Australia has problems of its own with its single, albeit newish reactor, and has recently been importing isotopes from South Africa.───尽管澳大利亚唯一的反应堆还是较新的，但仍存在不少问题，最近澳大利亚一直在从南非进口同位素。
a heavy toxic silvery-white radioactive metallic element; occurs in many isotopes; used for nuclear fuels and nuclear weapons.───一种重且有毒的银白色放射性金属元素，有许多同位素，用于核燃料和核武器中。
On my 12th birthday, I really wanted a titanium centrifuge so, you know, I could separate radioactive isotopes. Of course.───我12岁生日的时候，我非常想要一个钛离心分离机，这样，我就可以分离放射性同位素了。当然。
He said a heavy-water reactor is inappropriate for producing medical isotopes as Iran claims is its intention.───他说，伊朗声称建设重水反应堆是为了生产医用同位素，但重水反应堆并不适合于生产同位素。
Carbon has three naturally occurring isotopes, that is, atoms of the same atomic number but different atomic weights.
The isotopes are measured by counting their alpha emissions; each isotope emits alpha radiation of a characteristic frequency.
Asteroids contain a variety of rare radioactive isotopes of potassium, uranium, thorium, rubidium, and so on.
Typically, the fuels are isotopes of the three lightest elements, hydrogen, helium, and lithium.
The isotopes give off long-lasting alpha radiation and the waste will remain dangerous for 3000 years or more.
The use of light isotopes in a fusion reactor has been under experimental study since the 1950s.
Uranium has two radioactive isotopes, each of which decays to an isotope of lead and helium.
Tritium is one of the mildest radioactive isotopes.
Electricity produced by radioactive isotopes, strontium 90, polonium 210, by thermoelectric energy conversion.
