氡容易离子化，这让人期望，该元素有最广泛的化学反应，但是，这个元素最稳定的同位素也极不稳定，这使氡的研究受到了严重的约束。

Although the easier ionization of radon leads one to expect the most extensive chemistry for that element, the high instability of even the most stable isotope has severely limited studies of it.

那么，如果我们放出了能量，你认为氯离子比氯原子，更稳定还是更不稳定呢？

So, if we have energy that's released, would you say that the chlorine ion is more or less stable than the chlorine atom?

由于锂漂移型探测器有噪声大、不稳定等弱点，我们在新一代仪器上采用了离子注入型pin探测器。

Because the lithium drifting detector has the noise in a big way, unstable and so on the weakness, we have used the ion implantation PIN detector on the new generation of instrument.
