We record the products of the muon decays when they spin around like that.

我们记录了 μ 子像那样旋转时衰变的产物。

This detector is extra good at measuring particles that form after smashing protons together, and their radioactive decay products.

该探测器特别擅长测量质子碰撞后形成的粒子及其放射性衰变产物。

The age of a band can be determined by analysis of the radioactive isotopes within it, particularly those of uranium and its decay products.

条带的年龄可以通过分析其中的放射性同位素来确定，尤其是铀及其衰变产物。
